United States Public Health Service Commissioned Corps
The United States Public Health Service Commissioned Corps referred to as the Commissioned Corps of the United States Public Health Service, is the federal uniformed service of the U. S. Public Health Service, is one of the seven uniformed services of the United States. Along with the NOAA Commissioned Officer Corps, the Public Health Service Commissioned Corps is one of two uniformed services that consist only of commissioned officers and has no enlisted or warrant officer ranks, although warrant officers have been authorized for use within the service. Officers of the PHS are classified as noncombatants, unless directed to serve as and part of the armed forces by the President or detailed to a service branch of the armed forces. Members of the commissioned corps wear the same uniforms as the United States Navy, or the United States Coast Guard, with special PHS Commissioned Corps insignia, hold ranks equivalent to officers of the U. S. Navy and U. S. Coast Guard. Officers of the commissioned corps receive their commissions through the PHS Commissioned Corps's direct commissioning program.
As with its parent division, the Public Health Service, the commissioned corps is under the direction of the United States Department of Health and Human Services. The commissioned corps is led by the Surgeon General; the Surgeon General reports directly to the Department of Health and Human Services, Assistant Secretary for Health. The Public Health Service Commissioned Corps had its beginnings with the creation of the Marine Hospital Fund in 1798, reorganized in 1871 as the Marine Hospital Service; the Marine Hospital Service was charged with the care and maintenance of merchant sailors, but as the country grew, so did the ever-expanding mission of the service. The Marine Hospital Service soon began taking on new expanding health roles that included such health initiatives that protected the commerce and health of America. One such role was quarantine. John Maynard Woodworth, a famous surgeon of the Union Army who served under General William Tecumseh Sherman, was appointed in 1871 as the Supervising Surgeon.
Woodworth's title was changed to "Supervising Surgeon General," which became the Surgeon General of the United States. Woodworth is credited with the formal creation of the Commissioned Corps. Woodworth organized the Marine Hospital Service medical personnel along Army military structure in 1889 to facilitate a mobile force of health professionals that could be moved for the needs of the service and country, he established appointment standards and designed the Marine Hospital Service herald of a fouled anchor and caduceus. That year of 1889, President Grover Cleveland signed an Act into law that formally established the modern Public Health Service Commissioned Corps. At first open only to physicians, over the course of the twentieth century, the Corps expanded to 11 careers in a wide range of specialties to include veterinarians, engineers, nurses, environmental health specialists, scientists and other allied health professionals. Today, the commissioned corps is under the United States Public Health Service, a major agency now of the U.
S. Department of Health and Human Services, established by Congress in 1979-1980, it was established in 1953 as the U. S. Department of Health and Welfare, is still led by the Surgeon General; the commissioned corps allocates officers to all seven uniformed services depending on the health or medical needs of the other uniformed services. The commissioned corps was featured in the 1950 motion picture Panic in the Streets, in which Richard Widmark portrayed a Public Health Service physician tracking down a bubonic plague victim; the stated mission of the Commissioned Corps of the U. S. Public Health Service is "Protecting and advancing the health and safety of the Nation" in accordance with the commissioned corps's four Core Values: Leadership, Excellence and Service. Officers execute the mission of the commissioned corps in the following ways: Help provide healthcare and related services to medically underserved populations: to American Indians, Alaska Natives, to other population groups with special needs.
Plus, the commissioned corps provides officers to other uniformed services the United States Coast Guard and the National Oceanic and Atmospheric Administration Commissioned Officer Corps. Commissioned corps officers may be detailed to other federal agencies including the Department of Defense, TRICARE, Department of Justice, State Department, Department of Homeland Security, the Department of the Interior. Commissioned corps officers may develop individual memoranda of understanding with other o
George Washington was an American political leader, military general and Founding Father who served as the first president of the United States from 1789 to 1797. He led Patriot forces to victory in the nation's War of Independence, he presided at the Constitutional Convention of 1787 which established the new federal government, he has been called the "Father of His Country" for his manifold leadership in the formative days of the new nation. Washington received his initial military training and command with the Virginia Regiment during the French and Indian War, he was elected to the Virginia House of Burgesses and was named a delegate to the Continental Congress, where he was appointed Commanding General of the nation's Continental Army. Washington allied with France, in the defeat of the British at Yorktown. Once victory for the United States was in hand in 1783, Washington resigned his commission. Washington played a key role in the adoption and ratification of the Constitution and was elected president by the Electoral College in the first two elections.
He implemented a strong, well-financed national government while remaining impartial in a fierce rivalry between cabinet members Thomas Jefferson and Alexander Hamilton. During the French Revolution, he proclaimed a policy of neutrality while sanctioning the Jay Treaty, he set enduring precedents for the office of president, including the title "President of the United States", his Farewell Address is regarded as a pre-eminent statement on republicanism. Washington utilized slave labor and trading African American slaves, but he became troubled with the institution of slavery and freed them in his 1799 will, he was a member of the Anglican Church and the Freemasons, he urged tolerance for all religions in his roles as general and president. Upon his death, he was eulogized as "first in war, first in peace, first in the hearts of his countrymen." He has been memorialized by monuments, geographical locations and currency, many scholars and polls rank him among the top American presidents. Washington's great-grandfather John Washington immigrated in 1656 from Sulgrave, England to the British Colony of Virginia where he accumulated 5,000 acres of land, including Little Hunting Creek on the Potomac River.
George Washington was born February 22, 1732 at Popes Creek in Westmoreland County and was the first of six children of Augustine and Mary Ball Washington. His father was a justice of the peace and a prominent public figure who had three additional children from his first marriage to Jane Butler; the family moved to Little Hunting Creek to Ferry Farm near Fredericksburg, Virginia. When Augustine died in 1743, Washington inherited ten slaves. Washington did not have the formal education that his older brothers received at Appleby Grammar School in England, but he did learn mathematics and surveying, he was talented in draftsmanship and map-making. By early adulthood, he was writing with "considerable force" and "precision."Washington visited Mount Vernon and Belvoir, the plantation that belonged to Lawrence's father-in-law William Fairfax, which fueled ambition for the lifestyle of the planter aristocracy. Fairfax became Washington's patron and surrogate father, Washington spent a month in 1748 with a team surveying Fairfax's Shenandoah Valley property.
He received a surveyor's license the following year from the College of Mary. He resigned from the job in 1750 and had bought 1,500 acres in the Valley, he owned 2,315 acres by 1752. In 1751, Washington made his only trip abroad when he accompanied Lawrence to Barbados, hoping that the climate would cure his brother's tuberculosis. Washington contracted smallpox during that trip, which immunized him but left his face scarred. Lawrence died in 1752, Washington leased Mount Vernon from his widow. Lawrence's service as adjutant general of the Virginia militia inspired Washington to seek a commission, Virginia's Lieutenant Governor Robert Dinwiddie appointed him as a major in December 1752 and as commander of one of the four militia districts; the British and French were competing for control of the Ohio Valley at the time, the British building forts along the Ohio River and the French doing between Lake Erie and the Ohio River. In October 1753, Dinwiddie appointed Washington as a special envoy to demand that the French vacate territory which the British had claimed.
Dinwiddie appointed him to make peace with the Iroquois Confederacy and to gather intelligence about the French forces. Washington met with Half-King Tanacharison and other Iroquois chiefs at Logstown to secure their promise of support against the French, his party reached the Ohio River in November, they were intercepted by a French patrol and escorted to Fort Le Boeuf where Washington was received in a friendly manner. He delivered the British demand to vacate to French commander Saint-Pierre, but the French refused to leave. Saint-Pierre gave Washington his official answer in a sealed envelope after a few days' delay, he gave Washington's party food and extra winter clothing for the trip back to Virginia. Washington completed the precarious mission in 77 days in difficult winter conditions and achieved a measure of distinction when his report was published in Virginia and London. In February 1754, Dinwiddie promoted Washington to lieutenant colonel and second-in-command of the 300-strong Virginia R
United States Army
The United States Army is the land warfare service branch of the United States Armed Forces. It is one of the seven uniformed services of the United States, is designated as the Army of the United States in the United States Constitution; as the oldest and most senior branch of the U. S. military in order of precedence, the modern U. S. Army has its roots in the Continental Army, formed to fight the American Revolutionary War —before the United States of America was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army; the United States Army considers itself descended from the Continental Army, dates its institutional inception from the origin of that armed force in 1775. As a uniformed military service, the U. S. Army is part of the Department of the Army, one of the three military departments of the Department of Defense; the U. S. Army is headed by a civilian senior appointed civil servant, the Secretary of the Army and by a chief military officer, the Chief of Staff of the Army, a member of the Joint Chiefs of Staff.
It is the largest military branch, in the fiscal year 2017, the projected end strength for the Regular Army was 476,000 soldiers. S. Army was 1,018,000 soldiers; as a branch of the armed forces, the mission of the U. S. Army is "to fight and win our Nation's wars, by providing prompt, land dominance, across the full range of military operations and the spectrum of conflict, in support of combatant commanders"; the branch participates in conflicts worldwide and is the major ground-based offensive and defensive force of the United States. The United States Army serves as the land-based branch of the U. S. Armed Forces. Section 3062 of Title 10, U. S. Code defines the purpose of the army as: Preserving the peace and security and providing for the defense of the United States, the Commonwealths and possessions and any areas occupied by the United States Supporting the national policies Implementing the national objectives Overcoming any nations responsible for aggressive acts that imperil the peace and security of the United StatesIn 2018, the Army Strategy 2018 articulated an eight-point addendum to the Army Vision for 2028.
While the Army Mission remains constant, the Army Strategy builds upon the Army's Brigade Modernization by adding focus to Corps and Division-level echelons. Modernization, reform for high-intensity conflict, Joint multi-domain operations are added to the strategy, to be completed by 2028; the Continental Army was created on 14 June 1775 by the Second Continental Congress as a unified army for the colonies to fight Great Britain, with George Washington appointed as its commander. The army was led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them; as the Revolutionary War progressed, French aid and military thinking helped shape the new army. A number of European soldiers came on their own to help, such as Friedrich Wilhelm von Steuben, who taught Prussian Army tactics and organizational skills; the army fought numerous pitched battles and in the South in 1780–1781, at times using the Fabian strategy and hit-and-run tactics, under the leadership of Major General Nathanael Greene, hit where the British were weakest to wear down their forces.
Washington led victories against the British at Trenton and Princeton, but lost a series of battles in the New York and New Jersey campaign in 1776 and the Philadelphia campaign in 1777. With a decisive victory at Yorktown and the help of the French, the Continental Army prevailed against the British. After the war, the Continental Army was given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army; the Regular Army was at first small and after General St. Clair's defeat at the Battle of the Wabash, the Regular Army was reorganized as the Legion of the United States, established in 1791 and renamed the United States Army in 1796; the War of 1812, the second and last war between the United States and Great Britain, had mixed results.
The U. S. Army did not conquer Canada but it did destroy Native American resistance to expansion in the Old Northwest and it validated its independence by stopping two major British invasions in 1814 and 1815. After taking control of Lake Erie in 1813, the U. S. Army seized parts of western Upper Canada, burned York and defeated Tecumseh, which caused his Western Confederacy to collapse. Following U. S. victories in the Canadian province of Upper Canada, British troops who had dubbed the U. S. Army "Regulars, by God!", were able to capture and burn Washington, defended by militia, in 1814. The regular army, however proved they were professional and capable of defeating the British army during the invasions of Plattsburgh and Baltimore, prompting British agreement on the rejected terms of a status quo ante bellum. Two weeks after a treaty was signed, Andrew Jackson defeated the British in the Battle of New Orleans and Siege of Fort St. Philip, became a national hero. U. S. troops and sailors captured HMS Cyane and Penguin in the final engagements of the war.
Per the treaty, both sides (the United S
History of the United States
The history of the United States, a country in North America began with the settlement of Indigenous people before 15,000 BC. Numerous cultures formed; the arrival of Christopher Columbus in the year of 1492 started the European colonization of the Americas. Most colonies formed after 1600. By the 1760s, thirteen British colonies contained 2.5 million people along the Atlantic coast east of the Appalachian Mountains. After defeating France, the British government imposed a series of new taxes after 1765, rejecting the colonists' argument that new taxes needed their approval. Tax resistance the Boston Tea Party, led to punitive laws by Parliament designed to end self-government in Massachusetts. Armed conflict began in 1775. In 1776 in Philadelphia, the Second Continental Congress declared the independence of the colonies as the United States of America. Led by General George Washington, it won the Revolutionary War with large support from France; the peace treaty of 1783 gave the new nation the land east of the Mississippi River.
The Articles of Confederation established a central government, but it was ineffectual at providing stability, as it could not collect taxes and had no executive officer. A convention in 1787 wrote a new Constitution, adopted in 1789. In 1791, a Bill of Rights was added to guarantee inalienable rights. With Washington as the first president and Alexander Hamilton his chief adviser, a strong central government was created. Purchase of the Louisiana Territory from France in 1803 doubled the size of the United States. A second and final war with Britain was fought in 1812. Encouraged by the notion of manifest destiny, U. S. territory expanded all the way to the Pacific coast. While the United States was large in terms of area, its population in 1790 was only 4 million. However, it grew reaching 7.2 million in 1810, 32 million in 1860, 76 million in 1900, 132 million in 1940, 321 million in 2015. Economic growth in terms of overall GDP was greater; however compared to European powers, the nation's military strength was limited in peacetime before 1940.
The expansion was driven by a quest for inexpensive land for yeoman farmers and slave owners. The expansion of slavery was controversial and fueled political and constitutional battles, which were resolved by compromises. Slavery was abolished in all states north of the Mason–Dixon line by 1804, but the South continued to profit from the institution from production of cotton. Republican Abraham Lincoln was elected in 1860 on a platform of halting the expansion of slavery. Seven Southern slave states created the foundation of the Confederacy, its attack of Fort Sumter against the Union forces started the Civil War. Confederate defeat led to the abolition of slavery. In the Reconstruction Era and voting rights were extended to freed slaves; the national government emerged much stronger, because of the Fourteenth Amendment in 1868, it gained the explicit duty to protect individual rights. However, when white Democrats regained their power in the South in 1877 by paramilitary suppression of voting, they passed Jim Crow laws to maintain white supremacy, new disfranchising constitutions that prevented most African Americans and many poor whites from voting.
This continued until gains of the Civil Rights Movement in the 1960s and passage of federal legislation to enforce constitutional rights were made. The United States became the world's leading industrial power at the turn of the 20th century due to an outburst of entrepreneurship in the Northeast and Midwest and the arrival of millions of immigrant workers and farmers from Europe; the national railroad network was completed and large-scale mining and factories industrialized the Northeast and Midwest. Mass dissatisfaction with corruption and traditional politics stimulated the Progressive movement, from the 1890s to 1920s, which led to many reforms including the 16th to 19th constitutional amendments, which brought the federal income tax, direct election of Senators and women's suffrage. Neutral during World War I, the United States declared war on Germany in 1917 and funded the Allied victory the following year. Women obtained the right to vote in 1920, with Native Americans obtaining citizenship and the right to vote in 1924.
After a prosperous decade in the 1920s, the Wall Street Crash of 1929 marked the onset of the decade-long worldwide Great Depression. Democratic President Franklin D. Roosevelt ended the Republican dominance of the White House and implemented his New Deal programs, which included relief for the unemployed, support for farmers, Social Security and a minimum wage; the New Deal defined modern American liberalism. After the Japanese attack on Pearl Harbor in 1941, the United States entered World War II and financed the Allied war effort and helped defeat Nazi Germany in the European theater, its involvement culminated in using newly invented nuclear weapons on two Japanese cities to defeat Imperial Japan in the Pacific theater. The United States and the Soviet Union emerged as rival superpowers in the aftermath of World War II. During the Cold War, the two countries confronted each other indirectly in the arms race, the Space Race, proxy wars, propaganda campaigns; the purpose of this was to stop the spread of communism.
In the 1960s, in large part due to the strength of the Civil Rights Movement, another wave of social reforms was enacted by enforcing the constitutional rights of voting and freedom of movement to African-Americans and other racial minorities. The Cold War ended when the Soviet Union was dissolved in 1991, leaving the United States
General of the Army Omar Nelson Bradley was a senior officer of the United States Army during and after World War II. Bradley was the first Chairman of the Joint Chiefs of Staff and oversaw the U. S. military's policy-making in the Korean War. Born in Randolph County, Bradley worked as a boilermaker before entering the United States Military Academy at West Point, he graduated from the academy in 1915 alongside Dwight D. Eisenhower as part of "the class the stars fell on." During World War I, Bradley guarded copper mines in Montana. After the war, Bradley taught at West Point and served in other roles before taking a position at the War Department under General George Marshall. In 1941, Bradley became commander of the United States Army Infantry School. After the U. S. entrance into World War II, Bradley oversaw the transformation of the 82nd Infantry Division into the first American airborne division. He received his first front-line command in Operation Torch, serving under General George S. Patton in North Africa.
After Patton was reassigned, Bradley commanded II Corps in the Tunisia Campaign and the Allied invasion of Sicily. He commanded the First United States Army during the Invasion of Normandy. After the breakout from Normandy, he took command of the Twelfth United States Army Group, which comprised forty-three divisions and 1.3 million men, the largest body of American soldiers to serve under a single field commander. After the war, Bradley headed the Veterans Administration, he became Chief of Staff of the United States Army in 1948 and Chairman of the Joint Chiefs of Staff in 1949. In 1950, Bradley was promoted to the rank of General of the Army, becoming the last of only nine people to be promoted to five-star rank in the United States Armed Forces, he was the senior military commander at the start of the Korean War, supported President Harry S. Truman's wartime policy of containment, he was instrumental in persuading Truman to dismiss General Douglas MacArthur in 1951 after MacArthur resisted administration attempts to scale back the war's strategic objectives.
Bradley left active duty in 1953 continued to serve in public and business roles until his death in 1981. Bradley, the son of schoolteacher John Smith Bradley and Mary Elizabeth Hubbard, was born into poverty in rural Randolph County, near Moberly. Bradley was named after Omar D. Gray, a local newspaper editor admired by his father, a local physician, Dr. James Nelson, he was of British ancestry, his ancestors having emigrated from Great Britain to Kentucky in the mid-1700s. He attended at least eight country schools; the elder Bradley never earned more than $40 a month in his lifetime, teaching school and sharecropping. The family never owned a horse, ox or mule; when Omar was 15, his father, with whom he credited passing on to him his love of books and shooting, died. His mother moved to Moberly and remarried. Bradley graduated from Moberly High School in 1910, an outstanding student and athlete, captain of both the baseball and track teams. Bradley was working as a 17-cents-an-hour boilermaker at the Wabash Railroad when he was encouraged by his Sunday school teacher at Central Christian Church in Moberly to take the entrance examination for the United States Military Academy at West Point, New York.
Bradley had been saving his money to enter the University of Missouri in Columbia, where he intended to study law. He finished second in the West Point placement exams at Jefferson Barracks Military Post in St. Louis, Missouri; the first-place winner was unable to accept the Congressional appointment and the nomination was passed to Bradley in August 1911. While at the academy, Bradley's devotion to sports prevented him from excelling academically, although he was 44th in a class of 164, he was a baseball star and played on semi-pro teams for no remuneration. He was considered one of the most outstanding college players in the nation during his junior and senior seasons at West Point, noted as both a power hitter and an outfielder with one of the best arms in his day, he rejected multiple offers choosing to pursue his Army career. While stationed at West Point as an instructor, Bradley became a Freemason in 1923, becoming a member of the West Point Lodge #877, Highland Falls, New York until his death.
Bradley's first wife, Mary Quayle, grew up across the street from him in Moberly, the orphaned daughter of the town's popular police chief. The pair attended Moberly High School together, they were pictured across from each other on the Moberly High School yearbook of 1910, The Salutar, although they did not date in high school. His picture bore the motto "calculative" and hers "linguistic." She earned a college degree in education. Moberly called Bradley its favorite son and throughout his life Bradley called Moberly his hometown and his favorite city in the world, he was a frequent visitor to Moberly throughout his career, was a member of the Moberly Rotary Club, played near handicap golf at the challenging Moberly Country Club course and had a "Bradley pew" at Central Christian Church. At West Point, Bradley played three years of varsity baseball including the 1914 team, from which every player who remained in the army became a general, he graduated from West Point in 1915 as part of a class that contained many future generals, which military historians have called "the class the stars fell on".
Bradley's Cullum Number is 5356. There were 59 general officers in that graduating class, among whom Bradley and Dwight D. Eisenhower atta
California is a state in the Pacific Region of the United States. With 39.6 million residents, California is the most populous U. S. the third-largest by area. The state capital is Sacramento; the Greater Los Angeles Area and the San Francisco Bay Area are the nation's second and fifth most populous urban regions, with 18.7 million and 9.7 million residents respectively. Los Angeles is California's most populous city, the country's second most populous, after New York City. California has the nation's most populous county, Los Angeles County, its largest county by area, San Bernardino County; the City and County of San Francisco is both the country's second-most densely populated major city after New York City and the fifth-most densely populated county, behind only four of the five New York City boroughs. California's $3.0 trillion economy is larger than that of any other state, larger than those of Texas and Florida combined, the largest sub-national economy in the world. If it were a country, California would be the 5th largest economy in the world, the 36th most populous as of 2017.
The Greater Los Angeles Area and the San Francisco Bay Area are the nation's second- and third-largest urban economies, after the New York metropolitan area. The San Francisco Bay Area PSA had the nation's highest GDP per capita in 2017 among large PSAs, is home to three of the world's ten largest companies by market capitalization and four of the world's ten richest people. California is considered a global trendsetter in popular culture, innovation and politics, it is considered the origin of the American film industry, the hippie counterculture, fast food, the Internet, the personal computer, among others. The San Francisco Bay Area and the Greater Los Angeles Area are seen as global centers of the technology and entertainment industries, respectively. California has a diverse economy: 58% of the state's economy is centered on finance, real estate services and professional, scientific and technical business services. Although it accounts for only 1.5% of the state's economy, California's agriculture industry has the highest output of any U.
S. state. California is bordered by Oregon to the north and Arizona to the east, the Mexican state of Baja California to the south; the state's diverse geography ranges from the Pacific Coast in the west to the Sierra Nevada mountain range in the east, from the redwood–Douglas fir forests in the northwest to the Mojave Desert in the southeast. The Central Valley, a major agricultural area, dominates the state's center. Although California is well-known for its warm Mediterranean climate, the large size of the state results in climates that vary from moist temperate rainforest in the north to arid desert in the interior, as well as snowy alpine in the mountains. Over time and wildfires have become more pervasive features. What is now California was first settled by various Native Californian tribes before being explored by a number of European expeditions during the 16th and 17th centuries; the Spanish Empire claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its successful war for independence but was ceded to the United States in 1848 after the Mexican–American War.
The western portion of Alta California was organized and admitted as the 31st state on September 9, 1850. The California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom; the word California referred to the Baja California Peninsula of Mexico. The name derived from the mythical island California in the fictional story of Queen Calafia, as recorded in a 1510 work The Adventures of Esplandián by Garci Rodríguez de Montalvo; this work was the fifth in a popular Spanish chivalric romance series that began with Amadis de Gaula. Queen Calafia's kingdom was said to be a remote land rich in gold and pearls, inhabited by beautiful black women who wore gold armor and lived like Amazons, as well as griffins and other strange beasts. In the fictional paradise, the ruler Queen Calafia fought alongside Muslims and her name may have been chosen to echo the title of a Muslim leader, the Caliph. It's possible.
Know ye that at the right hand of the Indies there is an island called California close to that part of the Terrestrial Paradise, inhabited by black women without a single man among them, they lived in the manner of Amazons. They were robust of body with great virtue; the island itself is one of the wildest in the world on account of the craggy rocks. Shortened forms of the state's name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. Various estimates of the native population range from 100,000 to 300,000; the Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups were diverse in their political organization with bands, villages, on the resource-rich coasts, large chiefdoms, such as the Chumash and Salinan.

The United States of America known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U. S. is the third most populous country. The capital is Washington, D. C. and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico; the State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean; the U. S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The diverse geography and wildlife of the United States make it one of the world's 17 megadiverse countries.
Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century; the United States emerged from the thirteen British colonies established along the East Coast. Numerous disputes between Great Britain and the colonies following the French and Indian War led to the American Revolution, which began in 1775, the subsequent Declaration of Independence in 1776; the war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties; the United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, admitting new states until it spanned the continent by 1848. During the second half of the 19th century, the Civil War led to the abolition of slavery.
By the end of the century, the United States had extended into the Pacific Ocean, its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power; the United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U. S. Moon landing; the end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower. The United States is the world's oldest surviving federation, it is a representative democracy.
The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States, other international organizations. The United States is a developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for a quarter of global GDP; the U. S. economy is post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U. S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country. Despite wide income and wealth disparities, the United States continues to rank high in measures of socioeconomic performance, including average wage, human development, per capita GDP, worker productivity.
The United States is the foremost military power in the world, making up a third of global military spending, is a leading political and scientific force internationally.
