National Register of Historic Places
–
The National Register of Historic Places is the United States federal governments official list of districts, sites, buildings, structures, and objects deemed worthy of preservation. The passage of the National Historic Preservation Act in 1966 established the National Register, of the more than one million properties on the National Register,80,000 are listed individually. The remainder are contributing resources within historic districts, each year approximately 30,000 properties are added to the National Register as part of districts or by individual listings. For most of its history the National Register has been administered by the National Park Service and its goals are to help property owners and interest groups, such as the National Trust for Historic Preservation, coordinate, identify, and protect historic sites in the United States. While National Register listings are mostly symbolic, their recognition of significance provides some financial incentive to owners of listed properties, protection of the property is not guaranteed. During the nomination process, the property is evaluated in terms of the four criteria for inclusion on the National Register of Historic Places, the application of those criteria has been the subject of criticism by academics of history and preservation, as well as the public and politicians. Occasionally, historic sites outside the proper, but associated with the United States are also listed. Properties can be nominated in a variety of forms, including individual properties, historic districts, the Register categorizes general listings into one of five types of properties, district, site, structure, building, or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties, some properties are added automatically to the National Register when they become administered by the National Park Service. These include National Historic Landmarks, National Historic Sites, National Historical Parks, National Military Parks/Battlefields, National Memorials, on October 15,1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices. Initially, the National Register consisted of the National Historic Landmarks designated before the Registers creation, approval of the act, which was amended in 1980 and 1992, represented the first time the United States had a broad-based historic preservation policy. To administer the newly created National Register of Historic Places, the National Park Service of the U. S. Department of the Interior, hartzog, Jr. established an administrative division named the Office of Archeology and Historic Preservation. Hartzog charged OAHP with creating the National Register program mandated by the 1966 law, ernest Connally was the Offices first director. Within OAHP new divisions were created to deal with the National Register, the first official Keeper of the Register was William J. Murtagh, an architectural historian. During the Registers earliest years in the late 1960s and early 1970s, organization was lax and SHPOs were small, understaffed, and underfunded. A few years later in 1979, the NPS history programs affiliated with both the U. S. National Parks system and the National Register were categorized formally into two Assistant Directorates. Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation, from 1978 until 1981, the main agency for the National Register was the Heritage Conservation and Recreation Service of the United States Department of the Interior. In February 1983, the two assistant directorates were merged to promote efficiency and recognize the interdependency of their programs, jerry L. Rogers was selected to direct this newly merged associate directorate

National Monument (United States)
–
Historically, some national monuments were managed by the War Department. National monuments can be so designated through the power of the Antiquities Act of 1906, President Theodore Roosevelt used the act to declare Devils Tower in Wyoming as the first national monument. The Antiquities Act of 1906 resulted from concerns about protecting mostly prehistoric Native American ruins, the Act authorized permits for legitimate archaeological investigations and penalties for taking or destroying antiquities without permission. Among the next three monuments he proclaimed in 1906 was Petrified Forest in Arizona, another natural feature, in 1908, Roosevelt used the act to proclaim more than 800,000 acres of the Grand Canyon as a national monument. In 1918, President Woodrow Wilson proclaimed Katmai National Monument in Alaska, Katmai was later enlarged to nearly 2,800,000 acres by subsequent Antiquities Act proclamations and for many years was the largest national park system unit. Petrified Forest, Grand Canyon, and Katmai were among the national monuments later converted to national parks by Congress. Substantial opposition did not materialize until 1943, when President Franklin D. Roosevelt proclaimed Jackson Hole National Monument in Wyoming. He did this to accept a donation of lands acquired by John D. Rockefeller, roosevelts proclamation unleashed a storm of criticism about use of the Antiquities Act to circumvent Congress. A bill abolishing Jackson Hole National Monument passed Congress but was vetoed by Roosevelt, the proclamation authority was not used again anywhere until 1996, when President Bill Clinton proclaimed the Grand Staircase-Escalante National Monument in Utah. This action was unpopular in Utah, and bills were introduced to further restrict the presidents authority. To date, none of them have been enacted, presidents have used the Antiquities Acts proclamation authority not only to create new national monuments but to enlarge existing ones. For example, Franklin D. Roosevelt significantly enlarged Dinosaur National Monument in 1938, lyndon B. Johnson added Ellis Island to Statue of Liberty National Monument in 1965, and Jimmy Carter made major additions to Glacier Bay and Katmai National Monuments in 1978.

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located 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, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Salt marsh
–
It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the marsh in trapping and binding sediments. Salt marshes play a role in the aquatic food web. They also support terrestrial animals and provide coastal protection, salt marshes occur on low-energy shorelines in temperate and high-latitudes which can be stable or emerging, or submerging if the sedimentation rate exceeds the subsidence rate. Commonly these shorelines consist of mud or sand flats which are nourished with sediment from inflowing rivers and these typically include sheltered environments such as embankments, estuaries and the leeward side of barrier islands and spits. In the tropics and sub-tropics they are replaced by mangroves, an area that differs from a marsh in that instead of herbaceous plants. Most salt marshes have a low topography with low elevations but a vast wide area, salt marshes are located among different landforms based on their physical and geomorphological settings. Such marsh landforms include deltaic marshes, estuarine, back-barrier, open coast, embayments, deltaic marshes are associated with large rivers where many occur in Southern Europe such as the Camargue, France in the Rhone delta or the Ebro delta in Spain. They are also extensive within the rivers of the Mississippi Delta in the United States, in New Zealand, most salt marshes occur at the head of estuaries in areas where there is little wave action and high sedimentation. Such marshes are located in Awhitu Regional Park in Auckland, the Manawatu Estuary, back-barrier marshes are sensitive to the reshaping of barriers in the landward side of which they have been formed. They are common along much of the eastern coast of the United States, large, shallow coastal embayments can hold salt marshes with examples including Morecambe Bay and Portsmouth in Britain and the Bay of Fundy in North America. They have a big impact on the biodiversity of the area, salt marsh ecology involves complex food webs which include primary producers, primary consumers, and secondary consumers. The low physical energy and high grasses provide a refuge for animals, many marine fish use salt marshes as nursery grounds for their young before they move to open waters. Saltmarshes across 99 countries were mapped by Mcowen et al, a total of 5,495,089 hectares of mapped saltmarsh across 43 countries and territories are represented in a Geographic Information Systems polygon shapefile. This estimate is at the low end of previous estimates. Mats of filamentous blue-green algae can fix silt and clay sized sediment particles to their sticky sheaths on contact which can increase the erosion resistance of the sediments. This assists the process of sediment accretion to allow colonising species to grow, as a result, competitive species that prefer higher elevations relative to sea level can inhabit the area and often a succession of plant communities develops. Coastal salt marshes can be distinguished from terrestrial habitats by the tidal flow that occurs

Atlantic Ocean
–
The Atlantic Ocean is the second largest of the worlds oceans with a total area of about 106,460,000 square kilometres. It covers approximately 20 percent of the Earths surface and about 29 percent of its surface area. It separates the Old World from the New World, the Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. The Equatorial Counter Current subdivides it into the North Atlantic Ocean, in contrast, the term Atlantic originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of years ago. The term Aethiopian Ocean, derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century, many Irish or British people refer to the United States and Canada as across the pond, and vice versa. The Black Atlantic refers to the role of ocean in shaping black peoples history. Irish migration to the US is meant when the term The Green Atlantic is used, the term Red Atlantic has been used in reference to the Marxian concept of an Atlantic working class, as well as to the Atlantic experience of indigenous Americans. Correspondingly, the extent and number of oceans and seas varies, the Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea, to the east, the boundaries of the ocean proper are Europe, the Strait of Gibraltar and Africa. In the southeast, the Atlantic merges into the Indian Ocean, the 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean, the Atlantic has irregular coasts indented by numerous bays, gulfs, and seas. Including these marginal seas the coast line of the Atlantic measures 111,866 km compared to 135,663 km for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 or 23. 5% of the ocean and has a volume of 310,410,900 km3 or 23. 3%. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 and has a volume of 305,811,900 km3, the North Atlantic covers 41,490,000 km2 and the South Atlantic 40,270,000 km2. The average depth is 3,646 m and the maximum depth, the bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge. It runs from 87°N or 300 km south of the North Pole to the subantarctic Bouvet Island at 42°S, the MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2000 m along most of its length, the MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other

Florida
–
Florida /ˈflɒrᵻdə/ is a state located in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, Florida is the 22nd-most extensive, the 3rd-most populous, and the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States, the Miami metropolitan area is Floridas most populous urban area. The city of Tallahassee is the state capital, much of the state is at or near sea level and is characterized by sedimentary soil. The climate varies from subtropical in the north to tropical in the south, the American alligator, American crocodile, Florida panther, and manatee can be found in the Everglades National Park. It was a location of the Seminole Wars against the Native Americans. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, the states economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also renowned for amusement parks, orange crops, the Kennedy Space Center, Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, and continues to attract celebrities and athletes. It is internationally known for golf, tennis, auto racing, by the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee, the Timucua, the Ais, the Tocobaga, the Calusa and the Tequesta. Florida was the first part of the continental United States to be visited and settled by Europeans, the earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2,1513 and he named the region La Florida. The story that he was searching for the Fountain of Youth is a myth, in May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a wall of red mangroves spread mile after mile, some reaching as high as 70 feet. Very soon, many smokes appeared along the whole coast, billowing against the sky, the Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida. Both the Spanish and French established settlements in Florida, with varying degrees of success, in 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561. Spain maintained tenuous control over the region by converting the tribes to Christianity. The area of Spanish Florida diminished with the establishment of English settlements to the north, the English attacked St. Augustine, burning the city and its cathedral to the ground several times. Florida attracted numerous Africans and African-Americans from adjacent British colonies who sought freedom from slavery, in 1738, Governor Manuel de Montiano established Fort Gracia Real de Santa Teresa de Mose near St

National Park Service
–
It was created on August 25,1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. As of 2014, the NPS employs 21,651 employees who oversee 417 units, the National Park Service celebrated its centennial in 2016. National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior, the movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior and they wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational, inspirational, and recreational benefits. This campaign resulted in the creation of a National Park Service, Mather became the first director of the newly formed NPS. On March 3,1933, President Herbert Hoover signed the Reorganization Act of 1933, the act would allow the President to reorganize the executive branch of the United States government. It wasnt until later that summer when the new President, Franklin D. Roosevelt, President Roosevelt agreed and issued two Executive orders to make it happen. In 1951, Conrad Wirth became director of the National Park Service, the demand for parks after the end of the World War II had left the parks overburdened with demands that could not be met. In 1952, with the support of President Dwight D. Eisenhower, he began Mission 66, New parks were added to preserve unique resources and existing park facilities were upgraded and expanded. In 1966, as the Park Service turned 50 years old, emphasis began to turn from just saving great and wonderful scenery, Director George Hartzog began the process with the creation of the National Lakeshores and then National Recreation Areas. Since its inception in 1916, the National Park Service has managed each of the United States national parks, Yellowstone National Park was the first national park in the United States. In 1872, there was no government to manage it. Yosemite National Park began as a park, the land for the park was donated by the federal government to the state of California in 1864 for perpetual conservation. Yosemite was later returned to federal ownership, at first, each national park was managed independently, with varying degrees of success. In Yellowstone, the staff was replaced by the U. S. Army in 1886. Due to the irregularities in managing these national treasures, Stephen Mather petitioned the government to improve the situation. In response, Secretary of the Interior Franklin K. Lane challenged him to lobby for creating a new agency, Mather was successful with the ratification of the National Park Service Organic Act in 1916. Later, the agency was given authority over other protected areas, the National Park System includes all properties managed by the National Park Service

Castillo de San Marcos
–
The Castillo de San Marcos is the oldest masonry fort in the continental United States. Located on the shore of Matanzas Bay in the city of St. Augustine, Florida. Construction began in 1672,107 years after the founding by Spanish Admiral and conquistador Pedro Menéndez de Avilés. The forts construction was ordered by Governor Francisco de la Guerra y de la Vega after the raid of the English privateer Robert Searles in 1668. Work proceeded under the administration of Guerras successor, Manuel de Cendoya in 1671, the construction of the core of the current fortress was completed in 1695, though it would undergo many alterations and renovations over the centuries. The fort was declared a National Monument in 1924, and after 251 years of continuous military possession, was deactivated in 1933, the 20. 48-acre site was then turned over to the United States National Park Service. In 1942 the original name Castillo de San Marcos, was restored by an Act of Congress, Castillo de San Marcos was twice besieged, first by English colonial forces led by Carolina Colony Governor James Moore in 1702, and then by Georgia colonial Governor James Oglethorpe in 1740. The Native American art form known as Ledger Art had its origins at the fort during the imprisonment of members of the Plains tribes such as Howling Wolf of the southern Cheyenne. The European city of St. Augustine was founded by the admiral Pedro Menéndez de Avilés for the Spanish Crown in 1565 on the site of a former Native American village called Seloy. Over the next century, the Spanish built nine wooden forts for the defense of the town in various locations, the need for fortifications was recognized after it was attacked by Sir Francis Drake and his fleet of 22 ships in 1586. Following the 1668 attack of the English pirate Robert Searle, Mariana, Queen Regent of Spain, the Castillo is a masonry star fort made of a stone called coquina, made of ancient shells that have bonded together to form a type of stone similar to limestone. Workers were brought in from Havana, Cuba, to construct the fort in addition to Native American laborers. The coquina was quarried from the Kings Quarry on Anastasia Island in what is today Anastasia State Park across Matanzas Bay from the Castillo, construction began on October 2,1672 and lasted twenty-three years, with completion in 1695. The fort has four bastions named San Pedro, San Agustín, San Carlos, multiple embrasures were built into the curtain wall along the top of the fort as well as into the bastions for the deployment of cannon of various calibers. Infantry embrasures were built into the walls below the level of the terreplein for the deployment of muskets by the forts defenders. It was through one of these embrasures that twenty Seminoles held as prisoners would escape in 1837, in 1670, Charles Town was founded by English colonists. As it was just two days sail from St. Augustine, the English settlement and encroachment of English traders into Spanish territory spurred the Spanish in their construction of a fort. In 1702, English colonial forces under the command of Carolina Governor Governor James Moore embarked on an expedition to capture St. Augustine early in Queen Annes War, the English laid siege to St. Augustine in November 1702

James Oglethorpe
–
James Edward Oglethorpe was a British soldier, Member of Parliament, and philanthropist, as well as the founder of the colony of Georgia. As a social reformer, he hoped to resettle Britains worthy poor in the New World, James Oglethorpe was born in Surrey, the son of Sir Theophilus Oglethorpe of Westbrook Place, Godalming, and his wife Eleanor Lady Oglethorpe. He entered Corpus Christi College, Oxford in 1714, but in the year left to join the army of Prince Eugene of Savoy. After his return to England, he was elected Member of Parliament for Haslemere in 1722, in 1728 in Parliament, he advocated reform of the terrible conditions experienced by sailors in the British Royal Navy by publishing an anonymous pamphlet, The Sailors Advocate. In 1728, three years before conceiving the Georgia colony, Oglethorpe chaired a Parliamentary committee on prison reform, the committee documented horrendous abuses in three debtors prisons. As a result of the actions, many debtors were released from prison with no means of support. The petition was approved in 1732, and the first ship, led by Oglethorpe. Oglethorpe and the Trustees formulated a contractual, multi-tiered plan for the settlement of Georgia, the plan envisioned a system of agrarian equality, designed to support and perpetuate an economy based on family farming, and prevent social disintegration associated with unregulated urbanisation. Land ownership was limited to fifty acres, a grant that included a lot, a garden plot near town. Self-supporting colonists were able to obtain larger grants, but such grants were structured in fifty-acre increments tied to the number of indentured servants supported by the grantee, servants would receive a land grant of their own upon completing their term of service. No one was permitted to acquire land through purchase or inheritance. With Oglethorpe on that ship were cotton seeds provided by the Chelsea Medicinal Garden in London, the cotton seeds given to Oglethorpe were instrumental in establishing the cotton industry in the U. S. South. As discussed below, the plan for the colony was originally anti-slavery, but economic pressures eventually led to the lifting of the ban on slavery, as described below—and slavery was indispensable to the rise of large cotton-growing plantations throughout the Deep South. Oglethorpe and the first colonists arrived at South Carolina on the ship Anne in late 1732 and he negotiated with the Yamacraw tribe for land, and built a series of defensive forts, most notably Fort Frederica, of which substantial remains can still be visited. He then returned to England and arranged to have banned in Georgia after being emotionally moved by an intercepted letter from Ayuba Suleiman Diallo. Oglethorpe and his trustees were granted a royal charter for the Province of Georgia between the Savannah and Altamaha rivers on 9 June 1732. Georgia was a key contested area, lying in between the English Carolinas and Spanish Florida and it was Oglethorpes idea that British debtors should be released from prison and sent to Georgia. Although it is repeated that this would theoretically rid Britain of its so-called undesirable elements

Cuba
–
Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, the Gulf of Mexico, and it is south of both the U. S. state of Florida and the Bahamas, west of Haiti, and north of Jamaica. Havana is the largest city and capital, other cities include Santiago de Cuba. Cuba is the largest island in the Caribbean, with an area of 109,884 square kilometres, prior to Spanish colonization in the late 15th century, Cuba was inhabited by Amerindian tribes. It remained a colony of Spain until the Spanish–American War of 1898, as a fragile republic, Cuba attempted to strengthen its democratic system, but mounting political radicalization and social strife culminated in the dictatorship of Fulgencio Batista in 1952. Further unrest and instability led to Batistas ousting in January 1959 by the July 26 Movement, since 1965, the state has been governed by the Communist Party of Cuba. A point of contention during the Cold War between the Soviet Union and the United States, a nuclear war broke out during the Cuban Missile Crisis of 1962. Culturally, Cuba is considered part of Latin America, Cuba is a Marxist–Leninist one-party republic, where the role of the vanguard Communist Party is enshrined in the Constitution. Independent observers have accused the Cuban government of human rights abuses. It is one of the worlds last planned economies and its economy is dominated by the exports of sugar, tobacco, coffee, according to the Human Development Index, Cuba is described as a country with high human development and is ranked the eighth highest in North America. It also ranks highly in some metrics of national performance, including health care, the name Cuba comes from the Taíno language. The exact meaning of the name is unclear but it may be translated either as where fertile land is abundant, authors who believe that Christopher Columbus was Portuguese state that Cuba was named by Columbus for the town of Cuba in the district of Beja in Portugal. Before the arrival of the Spanish, Cuba was inhabited by three distinct tribes of indigenous peoples of the Americas, the Taíno, the Guanajatabey, and the Ciboney people. The ancestors of the Ciboney migrated from the mainland of South America, the Taíno arrived from Hispanola sometime in the 3rd century A. D. When Columbus arrived they were the dominant culture in Cuba, having a population of 150,000. The name Cuba comes from the native Taíno language and it is derived from either coabana meaning great place, or from cubao meaning where fertile land is abundant. The Taíno were farmers, while the Ciboney were farmers as well as fishers and hunter-gatherers, Columbus claimed the island for the new Kingdom of Spain and named it Isla Juana after Juan, Prince of Asturias. In 1511, the first Spanish settlement was founded by Diego Velázquez de Cuéllar at Baracoa, other towns soon followed, including San Cristobal de la Habana, founded in 1515, which later became the capital

Spanish Empire
–
The Spanish Empire was one of the largest empires in history. The Spanish Empire became the foremost global power of its time and was the first to be called the empire on which the sun never sets, the Spanish Empire originated during the Age of Discovery after the voyages of Christopher Columbus. Following the Spanish–American War of 1898, Spain ceded its last colonies in the Caribbean and its last African colonies were granted independence or abandoned during Decolonisation of Africa finishing in 1976. The unity did not mean uniformity, nevertheless, some historians assert that Portugal was part of the Spanish monarchy at the time, while others draw a clear distinction between the Portuguese and Spanish empires. During the 15th century, Castile and Portugal became territorial and commercial rivals in the western Atlantic. The conquest was completed with the campaigns of the armies of the Crown of Castile between 1478 and 1496, when the islands of Gran Canaria, La Palma, and Tenerife were subjugated. The Portuguese tried in vain to keep secret their discovery of the Gold Coast in the Gulf of Guinea, chronicler Pulgar wrote that the fame of the treasures of Guinea spread around the ports of Andalusia in such way that everybody tried to go there. Worthless trinkets, Moorish textiles, and above all, shells from the Canary and Cape Verde islands were exchanged for gold, slaves, ivory and Guinea pepper. The Crown officially organized this trade with Guinea, every caravel had to get a government license, the treaty delimited the spheres of influence of the two countries, establishing the principle of the Mare clausum. It was confirmed in 1481 by the Pope Sixtus IV, in the papal bull Æterni regis, thus, the limitations imposed by the Alcáçovas treaty were overcome and a new and more balanced worlds division would be reached at Tordesillas between both emerging maritime powers. Seven months before the treaty of Alcaçovas, King John II of Aragon died, Ferdinand and Isabella drove the last Moorish king out of Granada in 1492 after a ten-year war. The Catholic Monarchs then negotiated with Christopher Columbus, a Genoese sailor attempting to reach Cipangu by sailing west, Castile was already engaged in a race of exploration with Portugal to reach the Far East by sea when Columbus made his bold proposal to Isabella. Columbus discoveries inaugurated the Spanish colonization of the Americas and these actions gave Spain exclusive rights to establish colonies in all of the New World from north to south, as well as the easternmost parts of Asia. The treaty of Tordesillas was confirmed by Pope Julius II in the bull Ea quae pro bono pacis on 24 January 1506, Spains expansion and colonization was driven by economic influences, a yearning to improve national prestige, and a desire to spread Catholicism into the New World. The Catholic Monarchs had developed a strategy of marriages for their children in order to isolate their long-time enemy, the Spanish princes married the heirs of Portugal, England and the House of Habsburg. Following the same strategy, the Catholic Monarchs decided to support the Catalan-Aragonese house of Naples against Charles VIII of France in the Italian Wars beginning in 1494. As King of Aragon, Ferdinand had been involved in the struggle against France and Venice for control of Italy, these conflicts became the center of Ferdinands foreign policy as king. Only a year later, Ferdinand became part of the Holy League against France and this war was less of a success than the war against Venice, and in 1516, France agreed to a truce that left Milan in its control and recognized Spanish control of Upper Navarre

Ruins
–
Natural disaster, war and depopulation are the most common root causes, with many structures becoming progressively derelict over time due to long-term weathering and scavenging. Many ruins have become UNESCO World Heritage Sites in recent years, to identify, ancient cities were often highly militarized and fortified defensive settlements. In times of war they were the focus of armed conflict. Entire cities have also been ruined, and some occasionally lost completely, the ancient city of Pompeii was completely lost during a volcanic eruption in the 1st century AD, its uncovered ruins now preserved as a World Heritage Site. The city of Lisbon was totally destroyed in 1755 by an earthquake and tsunami. Apart from acts of war, some important historic buildings have fallen victim to deliberate acts of destruction as a consequence of social, political, marble was still being burned for agricultural lime in the Roman Camapgna into the nineteenth century. In Europe, many buildings suffered as a result of the politics of the day. In the 16th century, the English monarch Henry VIII set about confiscating the property of monastic institutions in a campaign which known as the Dissolution of the Monasteries. Many abbeys and monsateries fell into ruin when their assets, including lead roofs, were stripped, following World War II, a number of European historic buildings fell into ruin as a result of taxation policies, which required all structures with roofs to pay substantial property tax. The owners of buildings, like Fetteresso Castle and Slains Castle in Scotland, deliberately destroyed their roofs in protest at, and defiance of. Post-colonial Ireland has encouraged the ruin of grand Georgian houses, symbols of British imperialism, however, sometimes tower basements remain, because their removal can sometimes be expensive.
