The Reconstruction era was the period from 1863 to 1877 in American history. It was a significant chapter in the history of American civil rights; the term has two applications: the first applies to the complete history of the entire country from 1865 to 1877 following the American Civil War. Reconstruction ended the remnants of Confederate secession and ended slavery, making the newly-free slaves citizens with civil rights ostensibly guaranteed by three new Constitutional amendments. Three visions of Civil War memory appeared during Reconstruction: the reconciliationist vision, rooted in coping with the death and devastation the war had brought. Presidents Abraham Lincoln and Andrew Johnson both took moderate positions designed to bring the South back into the Union as as possible, while Radical Republicans in Congress sought stronger measures to upgrade the rights of African Americans, including the Fourteenth Amendment to the United States Constitution, while curtailing the rights of former Confederates, such as through the provisions of the Wade–Davis Bill.
Johnson, a former Tennessee Senator, former slave owner, the most prominent Southerner to oppose the Confederacy, followed a lenient policy toward ex-Confederates. Lincoln's last speeches show that he was leaning toward supporting the enfranchisement of all freedmen, whereas Johnson was opposed to this. Johnson's interpretations of Lincoln's policies prevailed until the Congressional elections of 1866; those elections followed outbreaks of violence against blacks in the former rebel states, including the Memphis riots of 1866 and the New Orleans riot that same year. The subsequent 1866 election gave Republicans a majority in Congress, enabling them to pass the 14th Amendment, take control of Reconstruction policy, remove former Confederates from power, enfranchise the freedmen. A Republican coalition came to power in nearly all the southern states and set out to transform the society by setting up a free labor economy, using the U. S. Army and the Freedmen's Bureau; the Bureau protected the legal rights of freedmen, negotiated labor contracts, set up schools and churches for them.
Thousands of Northerners came south as missionaries, teachers and politicians. Hostile whites began referring to these politicians as "carpetbaggers". In early 1866, Congress passed the Freedmen's Bureau and Civil Rights Bills and sent them to Johnson for his signature; the first bill extended the life of the bureau established as a temporary organization charged with assisting refugees and freed slaves, while the second defined all persons born in the United States as national citizens with equality before the law. After Johnson vetoed the bills, Congress overrode his vetos, making the Civil Rights Act the first major bill in the history of the United States to become law through an override of a presidential veto; the Radicals in the House of Representatives, frustrated by Johnson's opposition to Congressional Reconstruction, filed impeachment charges. The action failed by one vote in the Senate; the new national Reconstruction laws – in particular laws requiring suffrage for freedmen – incensed white supremacists in the South, giving rise to the Ku Klux Klan.
During 1867-69 the Klan murdered Republicans and outspoken freedmen in the South, including Arkansas Congressman James M. Hinds. Elected in 1868, Republican President Ulysses S. Grant supported Congressional Reconstruction and enforced the protection of African Americans in the South through the use of the Enforcement Acts passed by Congress. Grant used the Enforcement Acts to combat the Ku Klux Klan, wiped out, although a new incarnation of the Klan would again come to national prominence in the 1920s. President Grant was unable to resolve the escalating tensions inside the Republican Party between the Northerners on the one hand, those Republicans hailing from the South on the other. Meanwhile, "redeemers", self-styled conservatives in close cooperation with a faction of the Democratic Party opposed Reconstruction, they alleged widespread corruption by the "carpetbaggers", excessive state spending, ruinous taxes. Meanwhile, public support for Reconstruction policies, requiring continued supervision of the South, faded in the North after the Democrats, who opposed Reconstruction, regained control of the House of Representatives in 1874.
In 1877, as part of a Congressional bargain to elect Republican Rutherford B. Hayes as president following the disputed 1876 presidential election, U. S. Army troops were withdrawn from the three states; this marked the end of Reconstruction. Historian Eric Foner argues: What remains certain is that Reconstruction failed, that for blacks its failure was a disaster whose magnitude cannot be obscured by the genuine accomplishments that did endure. In different states Reconstruction ended at different times. In recent decades most historians follow Foner in dating the Reconstruction of the South as starting in 1863 rather than 1865; the usual ending for Reconstruction has always been 1877. Reconstruction policies were debated in the North when the
The Jamestown settlement in the Colony of Virginia was the first permanent English settlement in the Americas. It was located on the east bank of the James River about 2.5 mi southwest of the center of modern Williamsburg. It was established by the Virginia Company of London as "James Fort" on May 4, 1607 O. S.. It followed several failed attempts, including the Lost Colony of Roanoke, established in 1585 on Roanoke Island. Jamestown served as the capital of the colony of Virginia for 83 years, from 1616 until 1699; the settlement was located within the country of Tsenacommacah, which belonged to the Powhatan Confederacy, in that of the Paspahegh tribe. The natives welcomed and provided crucial provisions and support for the colonists, who were not agriculturally inclined. Relations soured early on, leading to the total annihilation of the Paspahegh in warfare within three years. Mortality was high at Jamestown itself due to disease and starvation, with over 80 percent of the colonists perishing in 1609–10 in what became known as the "Starving Time".
The Virginia Company brought eight Polish and German colonists in 1608 in the Second Supply, some of whom built a small glass factory—although the Germans and a few others soon defected to the Powhatans with weapons and supplies from the settlement. The Second Supply brought the first two European women to the settlement. In 1619, the first documented Africans came to Jamestown—about 50 men and children aboard a Portuguese slave ship, captured in the West Indies and brought to the Jamestown region, they most worked in the tobacco fields as indentured servants. The modern conception of slavery in the United States was formalized in 1640 and was entrenched in Virginia by 1660; the London Company's second settlement in Bermuda claims to be the site of the oldest town in the English New World, as St. George's, Bermuda was established in 1612 as New London, whereas James Fort in Virginia was not converted into James Towne until 1619, further did not survive to the present day. In 1676, Jamestown was deliberately burned during Bacon's Rebellion, though it was rebuilt.
In 1699, the capital was relocated from Jamestown to what is today Williamsburg, after which Jamestown ceased to exist as a settlement, existing today only as an archaeological site. Today, Jamestown is one of three locations composing the Historic Triangle of Colonial Virginia, along with Williamsburg and Yorktown, with two primary heritage sites. Historic Jamestowne is the archaeological site on Jamestown Island and is a cooperative effort by Jamestown National Historic Site and Preservation Virginia. Jamestown Settlement, a living history interpretive site, is operated by the Jamestown Yorktown Foundation, a state agency of the Commonwealth of Virginia. Spain and France moved to establish a presence in the New World, while other European countries moved more slowly; the English did not attempt to found colonies until many decades after the explorations of John Cabot, early efforts were failures—most notably the Roanoke Colony which vanished about 1590. Late in 1606, English colonizers set sail with a charter from the London Company to establish a colony in the New World.
The fleet consisted of the ships Susan Constant and Godspeed, all under the leadership of Captain Christopher Newport. They made a long voyage of four months, including a stop in the Canary Islands and subsequently Puerto Rico, departed for the American mainland on April 10, 1607; the expedition made landfall on April 1607 at a place which they named Cape Henry. Under orders to select a more secure location, they set about exploring what is now Hampton Roads and an outlet to the Chesapeake Bay which they named the James River in honor of King James I of England. Captain Edward Maria Wingfield was elected president of the governing council on April 25, 1607. On May 14, he selected a piece of land on a large peninsula some 40 miles inland from the Atlantic Ocean as a prime location for a fortified settlement; the river channel was a defensible strategic point due to a curve in the river, it was close to the land, making it navigable and offering enough land for piers or wharves to be built in the future.
The most favorable fact about the location was that it was uninhabited because the leaders of the nearby indigenous nations considered the site too poor and remote for agriculture. The island was swampy and isolated, it offered limited space, was plagued by mosquitoes, afforded only brackish tidal river water unsuitable for drinking; the Jamestown settlers arrived in Virginia during a severe drought, according to a research study conducted by the Jamestown Archaeological Assessment team in the 1990s. The JAA analyzed information from a study conducted in 1985 by David Stahle and others, who obtained borings of 800 year-old baldcypress trees along the Nottoway and Blackwater rivers; the lifespan of these trees is up to 1,000 years and their rings offer a good indication of an area's annual amount of rainfall. The borings revealed that the worst drought in 700 years occurred between 1606 and 1612; this severe drought affected the Jamestown colonists and Powhatan tribe's ability to produce food and obtain a safe supply of water.
The settlers arrived too late in the year to get crops planted. Many in the group were either gentlemen unused to work or their manservants, both unaccustomed to the hard labor demanded by the harsh task of carving out a viable colony. One of these was Robert Hunt, a former vicar of Reculver, England who
The Chesapeake Bay is an estuary in the U. S. states of Virginia. The Bay is located in the Mid-Atlantic region and is separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a important feature for the ecology and economy of those two states, as well as others. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile drainage basin, which covers parts of six states and all of Washington, D. C; the Bay is 200 miles long from its northern headwaters in the Susquehanna River to its outlet in the Atlantic Ocean. It is 2.8 miles wide at 30 miles at its widest. Total shoreline including tributaries is 11,684 miles, circumnavigating a surface area of 4,479 square miles. Average depth is 21 feet; the Bay is spanned twice, in Maryland by the Chesapeake Bay Bridge from Sandy Point to Kent Island and in Virginia by the Chesapeake Bay Bridge-Tunnel connecting Virginia Beach to Cape Charles.
Known for both its beauty and bounty, the Bay has become "emptier", with fewer crabs and watermen in past years. Recent restoration efforts begun in the 1990s have been ongoing and show potential for growth of the native oyster population; the health of the Chesapeake Bay improved in 2015, marking three years of gains over the past four years, according to a new report by the University of Maryland. The word Chesepiooc is an Algonquian word referring to a village "at a big river", it is the seventh oldest surviving English place-name in the United States, first applied as "Chesepiook" by explorers heading north from the Roanoke Colony into a Chesapeake tributary in 1585 or 1586. The name may refer to the Chesapeake people or the Chesepian, a Native American tribe who inhabited the area now known as South Hampton Roads in the U. S. state of Virginia. They occupied an area, now the Norfolk, Portsmouth and Virginia Beach areas. In 2005, Algonquian linguist Blair Rudes "helped to dispel one of the area's most held beliefs: that'Chesapeake' means something like'great shellfish bay.'
It does not, Rudes said. The name might have meant something like'great water,' or it might have just referred to a village location at the Bay's mouth." In addition, the name is always prefixed by "the" in usage by local residents: "The Chesapeake", "The Chesapeake Bay" and "The Bay". The Chesapeake Bay is an estuary to the North Atlantic, lying between the Delmarva Peninsula to the east and the North American mainland to the west, it is the ria, or drowned valley, of the Susquehanna River, meaning that it was the alluvial plain where the river flowed when the sea level was lower. It is not a fjord, because the Laurentide Ice Sheet never reached as far south as the northernmost point on the Bay. North of Baltimore, the western shore borders the hilly Piedmont region of Maryland; the large rivers entering the Bay from the west have broad mouths and are extensions of the main ria for miles up the course of each river. The Bay's geology, its present form, its location were created by a bolide impact event at the end of the Eocene, forming the Chesapeake Bay impact crater and the Susquehanna River valley much later.
The Bay was formed starting about 10,000 years ago when rising sea levels at the end of the last ice age flooded the Susquehanna River valley. Parts of the Bay the Calvert County, coastline, are lined by cliffs composed of deposits from receding waters millions of years ago; these cliffs known as Calvert Cliffs, are famous for their fossils fossilized shark teeth, which are found washed up on the beaches next to the cliffs. Scientists' Cliffs is a beach community in Calvert County named for the desire to create a retreat for scientists when the community was founded in 1935. Much of the Bay is shallow. At the point where the Susquehanna River flows into the Bay, the average depth is 30 feet, although this soon diminishes to an average of 10 feet southeast of the city of Havre de Grace, Maryland, to about 35 feet just north of Annapolis. On average, the depth of the Bay is 21 feet, including tributaries; because the Bay is an estuary, it has salt water and brackish water. Brackish water has three salinity zones: oligohaline and polyhaline.
The freshwater zone runs from the mouth of the Susquehanna River to north Baltimore. The oligohaline zone has little salt. Salinity varies from 0.5 ppt to 10 ppt, freshwater species can survive there. The north end of the oligohaline zone is north Baltimore and the south end is the Chesapeake Bay Bridge; the mesohaline zone has a medium amount of salt and runs from the Bay Bridge to the mouth of the Rappahannock River. Salinity there ranges from 10.7 ppt to 18 ppt. The polyhaline zone is the saltiest zone, some of the water can be as salty as sea water, it runs from the mouth of the Rappahannock River to the mouth of the Bay. The salinity ranges from 18.7 ppt to 36 ppt. The climate of the area surrounding the Bay i
Hertford County, North Carolina
Hertford County is a county located in the U. S. state of North Carolina. As of the 2010 census, the population was 24,669, its county seat is Winton. It is classified within the region known in the 21st century as the Inner Banks. Hertford County is home of the Meherrin Indian Tribe, descendants of indigenous people who had inhabited the region for many centuries. After decades of encroachment by English colonists, the Tribe moved south from Virginia, where they settled in 1706 on a reservation abandoned by the Chowanoke; this six-square-mile reservation was at Parker's Ferry near the mouth of the Meherrin River. It was confirmed by a treaty of 1726. However, they were not able to keep the reservation lands; the Tribe today has 900 enrolled members, most living within 10–15 miles of the former reservation. The tribe is seeking Federal recognition; the Meherrin have an annual Pow Wow at the end of October. The county was formed in 1759 from parts of Bertie County, Chowan County, Northampton County.
It was named for Francis Seymour-Conway, 1st Earl of Hertford 1st Marquess of Hertford. In 1779 the northeastern part of Hertford County was combined with parts of Chowan County and Perquimans County to form Gates County. According to the U. S. Census Bureau, the county has a total area of 360 square miles, of which 353 square miles is land and 7.3 square miles is water. Southampton County, Virginia – north Gates County – east Chowan County – southeast Bertie County – south Northampton County – west As of the census of 2010, there were 24,669 people, 8,953 households, 6,240 families residing in the county; the population density was 64 people per square mile. There were 9,724 housing units at an average density of 28 per square mile; the racial makeup of the county was 60.5% Black or African American, 35.6% White, 1.1% Native American, 0.5% Asian, 0.0% Pacific Islander, 0.8% from other races, 1.0% from two or more races. 1.4% of the population were Hispanic or Latino of any race. There were 8,953 households out of which 30.00% had children under the age of 18 living with them, 45.80% were married couples living together, 19.50% had a female householder with no husband present, 30.30% were non-families.
26.90% of all households were made up of individuals and 12.10% had someone living alone, 65 years of age or older. The average household size was 2.48 and the average family size was 2.99. In the county, the population was spread out with 25.30% under the age of 18, 7.80% from 18 to 24, 26.30% from 25 to 44, 24.80% from 45 to 64, 15.80% who were 65 years of age or older. The median age was 39 years. For every 100 females there were 85.00 males. For every 100 females age 18 and over, there were 79.50 males. The median income for a household in the county was $26,422, the median income for a family was $32,002. Males had a median income of $26,730 versus $20,144 for females; the per capita income for the county was $15,641. About 15.90% of families and 18.30% of the population were below the poverty line, including 21.30% of those under age 18 and 21.00% of those age 65 or over. Hertford County is a member of the Mid-East Commission regional council of governments. Rivers Correctional Institution, a private prison operated by the GEO Group which operates under contract from the Federal Bureau of Prisons and houses many felons who committed crimes in Washington, DC, is 1 mile from Winton.
Several large employers are located in Hertford County, including a run federal prison, Chowan University, a Nucor steel mill, several Perdue poultry processing facilities, an aluminum extrusion facility in Winton, a lumber-processing facility in Ahoskie. These industries, combined with a typical range of local retail and service businesses, combine to give Hertford County one of the lowest unemployment rates in Northeastern North Carolina; the larger area has lagged behind the rest of the state in terms of economic development. Hertford County Public Schools has seven schools ranging from pre-kindergarten to twelfth grade; these include three high schools, one middle school, three elementary schools. Hertford County is served by the Roanoke-Chowan News-Herald newspaper. There are five radio stations in Hertford County. WDLZ FM 98.3, an Adult Contemporary radio station and WWDR AM 1080, an Adult Urban Contemporary radio station are located in Murfreesboro. WQDK FM 99.3, a Country Music radio station and WRCS AM 970, an Urban Gosspel radio station are located in Ahoskie.

Thomas Harriot spelled Harriott, Hariot or Heriot, was an English astronomer, mathematician and translator who made advances within the scientific field. Thomas Harriot was recognized for his contributions in astronomy and navigational techniques. Harriot worked with John White to create advanced maps for navigation. While Harriot worked extensively on numerous papers on the subjects of astronomy and navigation the amount of work, published was sparse. So sparse, that the only publication, produced by Harriot was “the briefe and true report of the new found land of Virginia.” The premise of the book includes descriptions of English settlements and financial issues in Virginia at the time. He is sometimes credited with the introduction of the potato to the British Isles. Harriot was the first person to make a drawing of the Moon through a telescope, on 26 July 1609, over four months before Galileo. After graduating from St Mary Hall, Harriot travelled to the Americas, accompanying the 1585 expedition to Roanoke island funded by Sir Walter Raleigh and led by Sir Ralph Lane.
Harriot was a vital member of the venture, having learned and translating the Carolina Algonquian language from two Native Americans: Wanchese and Manteo. On his return to England, he worked for the 9th Earl of Northumberland. At the Earl's house, he became a prolific mathematician and astronomer to whom the theory of refraction is attributed. Born in 1560 in Oxford, Thomas Harriot attended St Mary Hall, Oxford, his name appears in the hall's registry dating from 1577. Harriot started to study navigation shortly after receiving a bachelor's degree from Oxford University; the study of navigation that Harriot studied concentrated on the idea of the open seas and how to cross to the New World from the Atlantic Ocean. He used instruments such as sextants to aide his studies of navigation. After educating himself by incorporating ideals from his astronomic and nautical studies, Harriot taught other captains his navigational techniques in Raleigh, his findings were recorded in the Articon but was never found.
After his graduation from Oxford in 1580, Harriot was first hired by Sir Walter Raleigh as a mathematics tutor. Prior to his expedition with Raleigh, Harriot wrote a treatise on navigation, he made efforts to communicate with Manteo and Wanchese, two Native Americans, brought to England. Harriot devised a phonetic alphabet to transcribe their Carolina Algonquian language. Harriot and Manteo spent many days in one another's company. In addition, he recorded the sense of awe with which the Native Americans viewed European technology: "Many things they sawe with us...as mathematical instruments, sea compasses... spring clocks that seemed to goe of themselves - and many other things we had - were so strange unto them, so farre exceeded their capacities to comprehend the reason and meanes how they should be made and done, that they thought they were rather the works of gods than men."He made only one expedition, around 1585-86, spent some time in the New World visiting Roanoke Island off the coast of North Carolina, expanding his knowledge by improving his understanding of the Carolina Algonquian language.
As the only Englishman who had learned Algonquin prior to the voyage, Harriot was vital to the success of the expedition. Hariot smoked tobacco before Raleigh, may have taught him to do so, his account of the voyage, named A Briefe and True Report of the New Found Land of Virginia, was published in 1588. The True Report contains an early account of the Native American population encountered by the expedition, he wrote: "Whereby it may be hoped, if means of good government be used, that they may in short time be brought to civility and the embracing of true religion." At the same time, his views of Native Americans' industry and capacity to learn were largely ignored in favour of the parts of the "True Report" about extractable minerals and resources. As a scientific adviser during the voyage, Harriot was asked by Raleigh to find the most efficient way to stack cannonballs on the deck of the ship, his ensuing theory about the close-packing of spheres shows a striking resemblance to atomism and modern atomic theory, which he was accused of believing.
His correspondence about optics with Johannes Kepler, in which he described some of his ideas influenced Kepler's conjecture. Harriot was employed for many years by Henry Percy, 9th Earl of Northumberland, with whom he resided at Syon House, run by Henry Percy's cousin Thomas Percy. Harriot's sponsors began to fall from favour: Raleigh was the first, Harriot's other patron Henry Percy, the Earl of Northumberland, was imprisoned in 1605 in connection with the Gunpowder Plot as he was connected to one of the conspirators, Thomas Percy. Around 1605, Harriot was imprisoned for a minimal amount of time due to the crimes involved with the Ninth Earl of Northumberland and the attempted assassination of King James I of England, known as the Jesuit Treason. While this was occurring, Harriot continued his work involving astronomy and in 1607, Harriot used his notes from the observations of the Halley's Comet to elaborate on his understanding of its orbit. Soon after in 1609 and 1610 Harriot turned his attention towards the physical aspects of the moon and
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960, it is based on the fact that radiocarbon is being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14C combines with atmospheric oxygen to form radioactive carbon dioxide, incorporated into plants by photosynthesis; when the animal or plant dies, it stops exchanging carbon with its environment, from that point onwards the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14C in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died; the older a sample is, the less 14C there is to be detected, because the half-life of 14C is about 5,730 years, the oldest dates that can be reliably measured by this process date to around 50,000 years ago, although special preparation methods permit accurate analysis of older samples.
Research has been ongoing since the 1960s to determine what the proportion of 14C in the atmosphere has been over the past fifty thousand years. The resulting data, in the form of a calibration curve, is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample's calendar age. Other corrections must be made to account for the proportion of 14C in different types of organisms, the varying levels of 14C throughout the biosphere. Additional complications come from the burning of fossil fuels such as coal and oil, from the above-ground nuclear tests done in the 1950s and 1960s; because the time it takes to convert biological materials to fossil fuels is longer than the time it takes for its 14C to decay below detectable levels, fossil fuels contain no 14C, as a result there was a noticeable drop in the proportion of 14C in the atmosphere beginning in the late 19th century. Conversely, nuclear testing increased the amount of 14C in the atmosphere, which attained a maximum in about 1965 of twice what it had been before the testing began.
Measurement of radiocarbon was done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14C atoms in a sample. More accelerator mass spectrometry has become the method of choice; the development of radiocarbon dating has had a profound impact on archaeology. In addition to permitting more accurate dating within archaeological sites than previous methods, it allows comparison of dates of events across great distances. Histories of archaeology refer to its impact as the "radiocarbon revolution". Radiocarbon dating has allowed key transitions in prehistory to be dated, such as the end of the last ice age, the beginning of the Neolithic and Bronze Age in different regions. In 1939, Martin Kamen and Samuel Ruben of the Radiation Laboratory at Berkeley began experiments to determine if any of the elements common in organic matter had isotopes with half-lives long enough to be of value in biomedical research, they synthesized 14C using the laboratory's cyclotron accelerator and soon discovered that the atom's half-life was far longer than had been thought.
This was followed by a prediction by Serge A. Korff employed at the Franklin Institute in Philadelphia, that the interaction of thermal neutrons with 14N in the upper atmosphere would create 14C, it had been thought that 14C would be more to be created by deuterons interacting with 13C. At some time during World War II, Willard Libby, at Berkeley, learned of Korff's research and conceived the idea that it might be possible to use radiocarbon for dating. In 1945, Libby moved to the University of Chicago, he published a paper in 1946 in which he proposed that the carbon in living matter might include 14C as well as non-radioactive carbon. Libby and several collaborators proceeded to experiment with methane collected from sewage works in Baltimore, after isotopically enriching their samples they were able to demonstrate that they contained 14C. By contrast, methane created from petroleum showed no radiocarbon activity because of its age; the results were summarized in a paper in Science in 1947, in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin.
Libby and James Arnold proceeded to test the radiocarbon dating theory by analyzing samples with known ages. For example, two samples taken from the tombs of two Egyptian kings and Sneferu, independently dated to 2625 BC plus or minus 75 years, were dated by radiocarbon measurement to an average of 2800 BC plus or minus 250 years; these results were published in Science in 1949. Within 11 years of their announcement, more than 20 radiocarbon dating laboratories had been set up worldwide. In 1960, Libby was awarded the Nobel Prize in Chemistry for this work. In nature, carbon exists as two stable, nonradioactive isotopes: carbon-12, carbon-13, a radioactive isotope, carbon-14 known as "radiocarbon"; the half-life
The English people are a nation and an ethnic group native to England who speak the English language. The English identity is of early medieval origin, when they were known in Old English as the Angelcynn, their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. England is one of the countries of the United Kingdom, the majority of people living there are British citizens; the English descend from two main historical population groups – the earlier Celtic Britons and the Germanic tribes who settled in Britain following the withdrawal of the Romans: the Angles, Saxons and Frisians. Collectively known as the Anglo-Saxons, they founded what was to become the Kingdom of England by the early 10th century, in response to the invasion and minor settlement of Danes beginning in the late 9th century; this was followed by the Norman Conquest and limited settlement of Anglo-Normans in England in the latter 11th century. In the Acts of Union 1707, the Kingdom of England was succeeded by the Kingdom of Great Britain.
Over the years, English customs and identity have become closely aligned with British customs and identity in general. Today many English people have recent forebears from other parts of the United Kingdom, while some are descended from more recent immigrants from other European countries and from the Commonwealth; the English people are the source of the English language, the Westminster system, the common law system and numerous major sports such as cricket, rugby union, rugby league and tennis. These and other English cultural characteristics have spread worldwide, in part as a result of the former British Empire; the concept of an'English nation' has become popular after the devolution process in Scotland and Northern Ireland resulted in the four nations having semi-independent political and legal systems. Although England itself has no devolved government, the 1990s witnessed a rise in English self-consciousness; this is linked to the expressions of national self-awareness of the other British nations of Wales and Scotland – which take their most solid form in the new devolved political arrangements within the United Kingdom – and the waning of a shared British national identity with the growing distance between the end of the British Empire and the present.
Many recent immigrants to England have assumed a British identity, while others have developed dual or mixed identities. Use of the word "English" to describe Britons from ethnic minorities in England is complicated by most non-white people in England identifying as British rather than English. In their 2004 Annual Population Survey, the Office for National Statistics compared the ethnic identities of British people with their perceived national identity, they found that while 58% of white people in England described their nationality as "English", the vast majority of non-white people called themselves "British". It is unclear. In the 2001 UK census, respondents were invited to state their ethnicity, but while there were tick boxes for'Irish' and for'Scottish', there were none for'English', or'Welsh', who were subsumed into the general heading'White British'. Following complaints about this, the 2011 census was changed to "allow respondents to record their English, Scottish, Northern Irish, Irish or other identity."
Another complication in defining the English is a common tendency for the words "English" and "British" to be used interchangeably outside the UK. In his study of English identity, Krishan Kumar describes a common slip of the tongue in which people say "English, I mean British", he notes that this slip is made only by the English themselves and by foreigners: "Non-English members of the United Kingdom say'British' when they mean'English'". Kumar suggests that although this blurring is a sign of England's dominant position with the UK, it is "problematic for the English when it comes to conceiving of their national identity, it tells of the difficulty that most English people have of distinguishing themselves, in a collective way, from the other inhabitants of the British Isles". In 1965, the historian A. J. P. Taylor wrote, "When the Oxford History of England was launched a generation ago, "England" was still an all-embracing word, it meant indiscriminately Wales. Foreigners indeed continue to do so.
Bonar Law, by origin a Scotch Canadian, was not ashamed to describe himself as "Prime Minister of England" Now terms have become more rigorous. The use of "England" except for a geographic area brings protests from the Scotch."However, although Taylor believed this blurring effect was dying out, in his book The Isles, Norman Davies lists numerous examples in history books of "British" still being used to mean "English" and vice versa. In December 2010, Matthew Parris in The Spectator, analysing the use of "English" over "British", argued that English identity, rather than growing, had existed all along but has been unmasked from behind a veneer of Britishness. David Reich's laboratory found that 90% of Britain's Neolithic gene pool was overturned by a population from North Continental Europe characterized by the Bell Beaker culture around 1200BC who carried a large amount of Yamnaya ancestry from the Pontic-Caspian Steppe, including the R1b Haplogroup; this population lacked genetic affinity to other Bell Beaker populations, such as the Iberian Bell Beakers, but appeared to be an offshoot of the Corded Ware single grave people
