The Adams–Onís Treaty (Spanish : Tratado de Adams-Onís) of 1819, also known as the Transcontinental Treaty, the Florida Purchase Treaty, or the Florida Treaty, was a treaty between the United States and Spain in 1819 that ceded Florida to the U.S. and defined the boundary between the U.S. and New Spain. It settled a standing border dispute between the two countries and was considered a triumph of American diplomacy. It came in the midst of increasing tensions related to Spain's territorial boundaries in North America against the United States and Great Britain in the aftermath of the American Revolution; it also came during the Latin American wars of independence.
Spanish or Castilian is a Romance language that originated in the Castile region of Spain and today has hundreds of millions of native speakers in the Americas and Spain. It is a global language and the world's second-most spoken native language, after Mandarin Chinese.
The United States of America (USA), commonly known as the United States or America, is a country comprising 50 states, a federal district, five major self-governing territories, and 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 slightly 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 extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.
Florida is the southernmost contiguous state in the United States. The state is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Atlantic Ocean, and to the south by the Straits of Florida. 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 the largest city by area in the contiguous United States. The Miami metropolitan area is Florida's most populous urban area. Tallahassee is the state's capital.
Florida had become a burden to Spain, which could not afford to send settlers or garrisons, so the Spanish government decided to cede the territory to the United States in exchange for settling the boundary dispute along the Sabine River in Spanish Texas. The treaty established the boundary of U.S. territory and claims through the Rocky Mountains and west to the Pacific Ocean, in exchange for the U.S. paying residents' claims against the Spanish government up to a total of $5,000,000 and relinquishing the U.S. claims on parts of Spanish Texas west of the Sabine River and other Spanish areas, under the terms of the Louisiana Purchase.
Garrison is the collective term for any body of troops stationed in a particular location, originally to guard it, but now often simply using it as a home base. The garrison is usually in a city, town, fort, castle, ship or similar. "Garrison town" is a common expression for any town that has a military base nearby.
The Sabine River is a river, 510 miles (820 km) long, in the Southern U.S. states of Texas and Louisiana. In its lower course, it forms part of the boundary between the two states and empties into Sabine Lake, an estuary of the Gulf of Mexico. Over the first half of the 19th century, the river formed part of the Spanish–American, Mexican–American, and Texan–American international boundaries. The upper reaches of the river flow through the prairie country of northeast Texas. Along much of its lower reaches, it flows through the pine forests along the Texas–Louisiana border, and the bayou country near the Gulf Coast.
Spanish Texas was one of the interior provinces of the Spanish colonial Viceroyalty of New Spain from 1690 until 1821.
The treaty remained in full effect for only 183 days: from February 22, 1821, to August 24, 1821, when Spanish military officials signed the Treaty of Córdoba acknowledging the independence of Mexico; Spain repudiated that treaty, but Mexico effectively took control of Spain's former colony. The Treaty of Limits between Mexico and the United States, signed in 1828 and effective in 1832, recognized the border defined by the Adams–Onís Treaty as the boundary between the two nations.
The Treaty of Córdoba established Mexican independence from Spain at the conclusion of the Mexican War of Independence. It was signed on August 24, 1821 in Córdoba, Veracruz, Mexico. The signatories were the head of the Army of the Three Guarantees, Agustín de Iturbide, and, acting on behalf of the Spanish government, Jefe Político Superior Juan O'Donojú. The treaty has 17 articles, which developed the proposals of the Plan of Iguala. The Treaty is the first document in which Spanish and Mexican officials accept the liberty of what will become the First Mexican Empire, but it is not today recognized as the foundational moment, since these ideas are often attributed to the Grito de Dolores. The treaty was rejected by the Spanish government. Spain did not recognize Mexico's independence until December 1836.
Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the tenth most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.
The Treaty of Limits between the United Mexican States and the United States of America is an 1828 treaty between Mexico and the United States that confirmed the borders between the two states. The Treaty of Limits was the first treaty concluded between the two countries.
The Adams–Onis Treaty was negotiated by John Quincy Adams, the Secretary of State under U.S. President James Monroe, and the Spanish "minister plenipotentiary" (diplomatic envoy) Luis de Onís y González-Vara, during the reign of King Ferdinand VII.
John Quincy Adams was an American statesman, diplomat, lawyer, and diarist who served as the sixth president of the United States from 1825 to 1829. He previously served as the eighth United States Secretary of State from 1817 to 1825. During his long diplomatic and political career, Adams also served as an ambassador, and represented Massachusetts as a United States Senator and as a member of the United States House of Representatives. He was the eldest son of John Adams, who served as the second US president from 1797 to 1801. Initially a Federalist like his father, he won election to the presidency as a member of the Democratic-Republican Party, and in the mid-1830s became affiliated with the Whig Party.
The Secretary of State is a senior official of the federal government of the United States of America, and as head of the United States Department of State, is principally concerned with foreign policy and is considered to be the U.S. government's equivalent of a Minister for Foreign Affairs.
James Monroe was an American statesman, lawyer, diplomat, and Founding Father who served as the fifth president of the United States from 1817 to 1825. A member of the Democratic-Republican Party, Monroe was the last president of the Virginia dynasty, and his presidency coincided with the Era of Good Feelings. He is perhaps best known for issuing the Monroe Doctrine, a policy of opposing European colonialism in the Americas. He also served as the governor of Virginia, a member of the United States Senate, the U.S. ambassador to France and Britain, the seventh Secretary of State, and the eighth Secretary of War.
Spain had long rejected repeated American efforts to purchase Florida. But by 1818, Spain was facing a troubling colonial situation in which the cession of Florida made sense. Spain had been exhausted by the Peninsular War (1807–1814) against Napoleon in Europe and needed to rebuild its credibility and presence in its colonies. Revolutionaries in Central America and South America were beginning to demand independence. Spain was unwilling to invest further in Florida, encroached on by American settlers, and it worried about the border between New Spain (a large area including today's Mexico, Central America, and much of the current US Western States) and the United States. With minor military presence in Florida, Spain was not able to restrain the Seminole warriors who routinely crossed the border and raided American villages and farms, as well as protected southern slave refugees from slave owners and traders of the southern United States.
The Peninsular War (1807–1814) was a military conflict between Napoleon's empire and Bourbon Spain, for control of the Iberian Peninsula during the Napoleonic Wars. The war began when the French and Spanish armies invaded and occupied Portugal in 1807, and escalated in 1808 when France turned on Spain, previously its ally. The war on the peninsula lasted until the Sixth Coalition defeated Napoleon in 1814, and is regarded as one of the first wars of national liberation, significant for the emergence of large-scale guerrilla warfare.
The Seminole are a Native American people originally from Florida. Today, they principally live in Oklahoma with a minority in Florida, and comprise three federally recognized tribes: the Seminole Tribe of Oklahoma, the Seminole Tribe of Florida, and Miccosukee Tribe of Indians of Florida, as well as independent groups. The Seminole nation emerged in a process of ethnogenesis from various Native American groups who settled in Florida in the 18th century, most significantly northern Muscogee (Creeks) from what is now Georgia and Alabama. The word "Seminole" is derived from the Creek word simanó-li, which may itself be derived from the Spanish word cimarrón, meaning "runaway" or "wild one".
By 1819, Spain was forced to negotiate, as it was losing hold on its American empire, with its western territories primed to revolt.[ citation needed ] While fighting escaped African-American slaves, outlaws, and Native Americans in U.S.-controlled Georgia during the First Seminole War, American General Andrew Jackson had pursued them into Spanish Florida. He built Fort Scott, at the southern border of Georgia (i.e., the U.S.), and used it to destroy the Negro Fort in northwest Florida, whose existence was perceived as an intolerable disruptive risk by Georgia plantation owners.
Georgia is a state in the Southeastern United States. It began as a British colony in 1733, the last and southernmost of the original Thirteen Colonies to be established. Named after King George II of Great Britain, the Province of Georgia covered the area from South Carolina south to Spanish Florida and west to French Louisiana at the Mississippi River. Georgia was the fourth state to ratify the United States Constitution, on January 2, 1788. In 1802–1804, western Georgia was split to the Mississippi Territory, which later split to form Alabama with part of former West Florida in 1819. Georgia declared its secession from the Union on January 19, 1861, and was one of the original seven Confederate states. It was the last state to be restored to the Union, on July 15, 1870. Georgia is the 24th largest and the 8th most populous of the 50 United States. From 2007 to 2008, 14 of Georgia's counties ranked among the nation's 100 fastest-growing, second only to Texas. Georgia is known as the Peach State and the Empire State of the South. Atlanta, the state's capital and most populous city, has been named a global city. Atlanta's metropolitan area contains about 55% of the population of the entire state.
Andrew Jackson was an American soldier and statesman who served as the seventh president of the United States from 1829 to 1837. Before being elected to the presidency, Jackson gained fame as a general in the United States Army and served in both houses of Congress. As president, Jackson sought to advance the rights of the "common man" against a "corrupt aristocracy" and to preserve the Union.
To stop the Seminole based in East Florida from raiding Georgia settlements and offering havens for runaway slaves, the U.S. Army led increasingly frequent incursions into Spanish territory. This included the 1817–1818 campaign by Andrew Jackson that became known as the First Seminole War, after which the U.S. effectively seized control of Northeastern Florida; albeit for purposes of lawful government and administration (in the state of Georgia); but not for the outright annexation of territory for Georgia; for additional US Territory; or, for the creation of another U.S. state.
Adams said the U.S. had to take control because Florida (along the border of Georgia & Alabama Territory) had become "a derelict open to the occupancy of every enemy, civilized or savage, of the United States, and serving no other earthly purpose than as a post of annoyance to them."Spain asked for British intervention, but London declined to assist Spain in the negotiations. Some of President Monroe's cabinet demanded Jackson's immediate dismissal for invading Florida, but Adams realized that his success had given the U.S. a favorable diplomatic position. Adams was able to negotiate very favorable terms.
In 1521, the Spanish Empire created the Virreinato de Nueva España (Viceroyalty of New Spain) to govern its conquests in the Caribbean, North America, and later the Pacific Ocean. In 1682, La Salle claimed La Louisiane for France.For the Spanish Empire, this was an intrusion into the northeastern frontier of Nueva España. In 1691, Spain created the Province of Tejas in Nueva España in an attempt to inhibit French settlement west of the Mississippi River. Fearing the loss of his American territories in the Seven Years' War, King Louis XV of France ceded La Louisiane to King Charles III of Spain with the secret Treaty of Fontainebleau in 1762. The Treaty of Paris of 1763 split La Louisiane with the portion east of the Mississippi River becoming a part of British North America and the portion west of the river becoming the District of Luisiana of Nueva España. This eliminated the French threat to Nueva España, and the Spanish provinces of Luisiana, Tejas, and Santa Fe de Nuevo México coexisted with only loosely defined borders. In 1800, French First Consul Napoleon Bonaparte forced King Charles IV of Spain to cede Luisiana to France with the secret Third Treaty of San Ildefonso. Spain continued to administer Luisiana until 1802, when Spain publicly transferred the district to France. The following year, Napoleon sold La Louisiane to the United States to raise money for his military campaigns.
The United States and the Spanish Empire disagreed over the territorial boundaries of the Louisiana Purchase of 1803. The United States maintained the claim of France that Louisiana included the Mississippi River and "all lands whose waters flow to it." To the west of New Orleans, the United States assumed the French claim to all land east and north of the Sabine River.Spain maintained that all land west of the Calcasieu River and south of the Arkansas River belonged to Tejas and Santa Fe de Nuevo México (see #New Spain.)
The United Kingdom claimed the region west of the Continental Divide between the undefined borders of Alta California and Russian Alaska on the basis of (1) the third voyage of James Cook in 1778, (2) the Vancouver Expedition in 1791–1795, (3) the solo journey of Alexander Mackenzie to the North Bentinck Armin 1792–1793, and (4) the exploration of David Thompson in 1807–1812. The Third Nootka Convention of 1794 called for the joint and exclusive British–Spanish exploitation of the region.
The United States claimed essentially the same region on the basis of (1) the voyage of Robert Gray up the Columbia River in 1792, (2) the United States Lewis and Clark Expedition of 1804–1806, and (3) the establishment of Fort Astoriaon the Columbia River in 1811. On 20 October 1818, the Anglo-American Convention of 1818 was signed setting the border between British North America and the United States east of the Continental Divide along the 49th parallel north and calling for joint Anglo-American occupancy west of the Great Divide. The Anglo-American Convention ignored the Nootka Convention of 1794 which gave Spain joint rights in the region. The Convention also ignored Russian settlements in the region. The United States referred to this region as the Oregon Country, while the United Kingdom referred to the region as the Columbia District.
On 16 July 1741, the crew of the Imperial Russian Navy ship Saint Peter (Апостол Пётр), captained by Vitus Bering, sighted Mount Saint Elias, 105 kilometers (65 miles) northwest of the Spain's Presidio Real de San Francisco.the fourth-highest summit in North America. They became the first Europeans to land in northwestern North America. The Russian fur trade soon followed the discovery. By 1812, the Russian Empire claimed Alaska and the Pacific Coast of North America as far south as the Russian settlement of Fortress Ross, only
The Spanish Empire claimed all lands west of the Continental Divide throughout the Americas.Between 1774 and 1779, King Charles III of Spain ordered three naval expeditions north along the Pacific Coast to assert Spain's territorial claims. In July 1774, Juan José Pérez Hernández reached latitude 54°40′ north off the northwestern tip of Langara Island before being forced to turn south. On 15 August 1775, Juan Francisco de la Bodega y Quadra reached the latitude 59°0′ before returning south. On 23 July 1779, Ignacio de Arteaga y Bazán and Bodega y Quadra reached Puerto de Santiago on Isla de la Magdalena (now Port Etches on Hinchinbrook Island) where they held a formal possession ceremony commemorating Saint James, the patron saint of Spain. This marked the northernmost Spanish exploration in the Pacific Ocean.
Between 1788 and 1793, Spain launched several more expeditions north of Alta California. On 24 June 1789, Esteban José Martínez Fernández y Martínez de la Sierra established the Spanish colony of Santa Cruz de Nucaon the northwest coast of Vancouver Island. Asserting Spain's claim of exclusive sovereignty and navigation rights, Martínez seized several ships in Nootka Sound provoking the Nootka Crisis with the British Empire. In negotiations to resolve the crisis, Spain claimed that its Nootka Territory extended north from Alta California to the 61st parallel north and from the Continental Divide west to the 147th meridian west. On 11 January 1794, the Spanish Empire and the British Empire signed the Third Nootka Convention which called for the abandonment of all permanent settlements on Nootka Sound. Santa Cruz de Nuca was formally abandoned on 28 March 1795. The Convention also called for joint and exclusive British–Spanish exploitation of the Nootka Territory. On 19 August 1796, the Spanish Empire joined the French First Republic in war against the British Empire with the signing of the Second Treaty of San Ildefonso, thus ending Spanish and British cooperation in the Americas.
East of the Continental Divide, the Spanish Empire claimed all land south of the Arkansas River that was west of the Medina River and all land south of the Red River that was west of the Calcasieu River.The vast disputed region between the territorial claims of the United States and Spain was occupied primarily by native peoples with very few traders of either Spain or the United States. In the south, the disputed region between the Calcasieu River and the Sabine River encompassed Los Adaes, the first capital of Spanish Texas. The region between the Calcasieu and Sabine rivers become a lawless no man's land. The United States saw great potential in these western lands, and hoped to settle their borders. Spain, seeing the end of New Spain, hoped to employ its territorial claims before it would be forced to grant Mexico its independence (later in 1821). Spain hoped to regain much of its territory after the regional demands for independence subsided.
The treaty, consisting of 16 articleswas signed in Adams' State Department office at Washington, on February 22, 1819, by John Quincy Adams, U.S. Secretary of State, and Luis de Onís, Spanish minister. Ratification was postponed for two years, because Spain wanted to use the treaty as an incentive to keep the United States from giving diplomatic support to the revolutionaries in South America. As soon as the treaty was signed, the U.S. Senate ratified unanimously; but because of Spain's stalling, a new ratification was necessary and this time there were objections. Henry Clay and other Western spokesmen demanded that Spain also give up Texas. This proposal was defeated by the Senate, which ratified the treaty a second time on February 19, 1821, following ratification by Spain on October 24, 1820. Ratifications were exchanged three days later and the treaty was proclaimed on February 22, 1821, two years after the signing.
The Treaty closed the first era of United States expansion by providing for the cession of East Florida under Article 2; the abandonment of the controversy over West Florida under Article 2 (a portion of which had been seized by the United States); and the definition of a boundary with the Spanish province of Mexico, that clearly made Spanish Texas a part of Mexico, under Article 3, thus ending much of the vagueness in the boundary of the Louisiana Purchase. Spain also ceded to the U.S. its claims to the Oregon Country, under Article 3.
The U.S. did not pay Spain for Florida, but instead agreed to pay the legal claims of American citizens against Spain, to a maximum of $5 million, under Article 11.Under Article 12, Pinckney's Treaty of 1795 between the U.S. and Spain was to remain in force. Under Article 15, Spanish goods received exclusive most-favored-nation privileges in the ports at Pensacola and St. Augustine for twelve years.
Under Article 2, the U.S. received ownership of Spanish Florida (British East Florida and West Florida 1763–1783). Under Article 3, the U.S. relinquished its own claims on parts of Texas west of the Sabine River and other Spanish areas.
Article 3 of the treaty states:
The Boundary Line between the two Countries, West of the Mississippi, shall begin on the Gulf of Mexico, at the mouth of the River Sabine in the Sea (), continuing North, along the Western Bank of that River, to the 32d degree of Latitude ( ); thence by a Line due North to the degree of Latitude, where it strikes the Rio Roxo of Nachitoches, or Red-River ( ), then following the course of the Rio-Roxo Westward to the degree of Longitude, 100 West from London and 23 from Washington ( ), then crossing the said Red-River, and running thence by a Line due North to the River Arkansas ( ), thence, following the Course of the Southern bank of the Arkansas to its source in Latitude, 42. North and thence by that parallel of Latitude to the South-Sea [Pacific Ocean]. The whole being as laid down in Melishe's Map of the United States, published at Philadelphia, improved to the first of January 1818. But if the Source of the Arkansas River shall be found to fall North or South of Latitude 42, then the Line shall run from the said Source ( ) due South or North, as the case may be, till it meets the said Parallel of Latitude 42 ( ), and thence along the said Parallel to the South Sea ( ).
At the time the treaty was signed, the course of the Sabine River, Red River, and Arkansas River had only been partially charted. Furthermore, the rivers changed course periodically. It would take many years before the location of the border would be fully determined.
South of the 32nd parallel north, the Spanish Empire and the United States settled for the U.S. claim along the Sabine River. Between the meridians 94°2′45" and 100° west, the parties settled on the Spanish claim along the Red River. West of the 100th meridian west, the parties settled on the Spanish claim along the Arkansas River. From the source of the Arkansas River in the Rocky Mountains, the parties settled on a border due north along that meridian (106°20′37″W) to the 42nd parallel north, thence west along the 42nd parallel to the Pacific Ocean.
Spain won substantial buffer zones around its provinces of Tejas, Santa Fe de Nuevo México, and Alta California in New Spain. While the United States relinquished substantial territory east of Continental Divide, the newly defined border allowed settlement of the southwestern part of the State of Louisiana, the Territory of Arkansaw, and the Territory of Missouri.
Spain relinquished all claims in the Americas north of the 42nd parallel north. This was a historic retreat in its 327-year pursuit of lands in the Americas. The previous Anglo-American Convention of 1818 meant that both the United States and the British Empire could settle land north of the 42nd parallel and west of the Continental Divide. The United States now had a firm foothold on the Pacific Coast and could commence settlement of the jointly occupied Oregon Country (known as the Columbia District to the rival United Kingdom). The Russian Empire also claimed this entire region as part of Russian America.
For the United States, this Treaty (and the Treaty of 1818 with Britain agreeing to joint occupancy of the Pacific Northwest) meant that its claimed territory now extended far west from the Mississippi River to the Pacific Ocean. For Spain, it meant that it kept its colony of Texas and also kept a buffer zone between its colonies in California and New Mexico and the U.S. territories. Many historians consider the Treaty to be a great achievement for the U.S., as time validated Adams's vision that it would allow the U.S. to open trade with the Orient across the Pacific.
Informally this new border has been called the "Step Boundary," although the step-like shape of the boundary was not apparent for several decades—the source of the Arkansas, believed to be near the 42nd parallel north, was not known until John C. Frémont located it in the 1840s, hundreds of miles south of the 42nd parallel.
Washington set up a commission, 1821 to 1824, that handled American claims against Spain. Many notable lawyers, including Daniel Webster and William Wirt, represented claimants before the commission. During its term, the commission examined 1,859 claims arising from over 720 spoliation incidents, and distributed the $5 million in a basically fair manner.The treaty reduced tensions with Spain (and after 1821 Mexico), and allowed budget cutters in Congress to reduce the army budget and reject the plans to modernize and expand the army proposed by Secretary of War John C. Calhoun.
The treaty was honored by both sides, although inaccurate maps from the treaty meant that the boundary between Texas and Oklahoma remained unclear for most of the 19th century. The American boundary was expanded in 1848 by the Treaty of Guadalupe Hidalgo with Mexico.
The treaty was ratified by Spain in 1820, and by the United States in 1821 (during the time that Spain and Mexico were engaged in the prolonged Mexican War of Independence). Spain finally recognized the independence of Mexico with the Treaty of Córdoba signed on August 24, 1821. While Mexico was not initially a party to the Adams–Onís Treaty, in 1831 Mexico ratified the treaty by agreeing to the 1828 Treaty of Limits with the U.S.
With the Russo-American Treaty of 1824, the Russian Empire ceded its claims south of parallel 54°40′ north to the United States. With the Treaty of Saint Petersburg in 1825, Russia set the southern border of Alaska on the same parallel in exchange for the Russian right to trade south of that border and the British right to navigate north of that border. This set the absolute limits of the Oregon Country/Columbia District between the 42nd parallel north and the parallel 54°40′ north west of the Continental Divide.
By the mid-1830s, a controversy developed regarding the border with Texas, during which the United States demonstrated that the Sabine and Neches rivers had been switched on maps, moving the frontier in favor of Mexico. As a consequence, the eastern boundary of Texas was not firmly established until the independence of the Republic of Texas in 1836. It was not agreed upon by the United States and Mexico until the Treaty of Guadalupe Hidalgo in 1848, which concluded the Mexican–American War. That treaty also formalized the cession by Mexico of Alta California and today's American Southwest, except for the territory of the later Gadsden Purchase of 1854.
Another dispute occurred after Texas joined the Union. The treaty stated that the boundary between the French claims on the north and the Spanish claims on the south was Rio Roxo de Natchitoches (Red River) until it reached the 100th meridian, as noted on the John Melish map of 1818. But, the 100th meridian on the Melish map was marked some 90 miles (140 km) east of the true 100th meridian, and the Red River forked about 50 miles (80 km) east of the 100th meridian. Texas claimed the land south of the North Fork, and the United States claimed the land north of the South Fork (later called the Prairie Dog Town Fork Red River). In 1860 Texas organized the area as Greer County. The matter was not settled until a United States Supreme Court ruling in 1896 upheld federal claims to the territory, after which it was added to the Oklahoma Territory.
The treaty gave rise to a later border dispute between the states of Oregon and California, which remains unresolved. Upon statehood in 1850, California established the 42nd parallel as its constitutional de jure border as it had existed since 1819 when the territory was part of Spanish Mexico. In an 1868–1870 border survey following the admission of Oregon as a state, errors were made in demarcating and marking the Oregon-California border, creating a dispute that continues to this day.
The Louisiana Purchase was the acquisition of the territory of Louisiana by the United States from France in 1803. In return for fifteen million dollars, the U.S. acquired a total of 828,000 sq mi. The treaty was negotiated by French Treasury Minister François Barbé-Marbois and American delegates James Monroe and Robert R. Livingston.
Beauregard Parish is a parish located in the U.S. state of Louisiana. As of the 2010 census, the population was 35,654. The parish seat is DeRidder. The parish was formed on January 1, 1913.
West Florida was a region on the northern coast of the Gulf of Mexico that underwent several boundary and sovereignty changes during its history. As its name suggests, it was formed out of the western part of former Spanish Florida, along with lands taken from French Louisiana; Pensacola became West Florida's capital. The colony included about two thirds of what is now the Florida Panhandle, as well as parts of the modern U.S. states of Louisiana, Mississippi, and Alabama.
Pinckney's Treaty, also commonly known as the Treaty of San Lorenzo or the Treaty of Madrid, was signed in San Lorenzo de El Escorial on October 27, 1795 and established intentions of friendship between the United States and Spain. It also defined the border between the United States and Spanish Florida, and guaranteed the United States navigation rights on the Mississippi River. With this agreement, the first phase of the ongoing border dispute between the two nations in this region, commonly called the West Florida Controversy, came to a close.
This is a list of United States territorial acquisitions and conquests, beginning with American independence. Note that this list primarily concerns land the United States of America acquired from other nation-states. Early American expansion was tied to a national concept of manifest destiny. Manifest destiny is an idea that white settlers are destined by God to expand their territories westwards, spread their ideologies on the land, and put leverages on the Indigenous people in order to gain larger territories. Manifest Destiny not only resulted in war with Mexico during the mid-19th century, but in relocation and brutal massacre and mistreatment of the Indigenous peoples, Hispanic, and other non-Europeans, such as afro-descendants, who resided in the territories no occupied by the United States.
The Territory of New Mexico was an organized incorporated territory of the United States that existed from September 9, 1850, until January 6, 1912, when the remaining extent of the territory was admitted to the Union as the State of New Mexico, making it the longest-lived organized incorporated territory of the United States, lasting approximately 62 years.
The Mexican Cession is the region in the modern-day southwestern United States that Mexico ceded to the U.S. in the Treaty of Guadalupe Hidalgo in 1848 after the Mexican–American War. This region had not been part of the areas east of the Rio Grande which had been claimed by the Republic of Texas, though the Texas annexation resolution two years earlier had not specified the southern and western boundary of the new State of Texas.
