Adams–Onís Treaty in the context of "Spanish Texas"

The Treaty of Peace between the United States of America and the Kingdom of Spain, commonly known as the Treaty of Paris of 1898, was signed by Spain and the United States on December 10, 1898, and marked the official end of the Spanish–American War. Under it, Spain relinquished all claim of sovereignty over the West Indies archipelagos and islands of Cuba and Puerto Rico in the Caribbean, the Western Pacific island of Guam in the Marianas archipelago in Micronesia, and the Western Pacific archipelago of the Philippines in Southeast Asia to the United States. The cession of the Philippines involved a compensation of $20 million from the United States to Spain.

The treaty was preceded by the Spanish-American War armistice, a preliminary peace agreement signed on August 12, 1898 in Washington, DC. The armistice formally stopped the active hostilities between Spain and the United States, requiring Spain to cede Cuba, Puerto Rico, and Guam to the United States, and to agree to the American occupation of Manila in the Philippines. The treaty came into effect on April 11, 1899, when the documents of ratification were exchanged. It was the first treaty negotiated between the two governments since the 1819 Adams–Onís Treaty.

Florida (/ˈflɒrɪdə/ FLORR-ih-də; Spanish: [floˈɾiða] ) is a state in the Southeastern and South Atlanticregions of the United States. It borders the Gulf of Mexico to the west, Alabama to the northwest, Georgia to the north, the Atlantic Ocean to the east, the Straits of Florida to the south, and The Bahamas to the southeast. About two-thirds of Florida occupies a peninsula between the Gulf of Mexico and the Atlantic Ocean. It has the longest coastline in the contiguous United States, spanning approximately 1,350 miles (2,170 km), not including its many barrier islands. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. With a population of over 23 million, it is the third-most populous state in the United States and ranks seventh in population density as of 2020. Florida spans 65,758 square miles (170,310 km), ranking 22nd in area among the states. The Miami metropolitan area, anchored by the cities of Miami, Fort Lauderdale, and West Palm Beach, is the state's largest metropolitan area, with a population of 6.138 million; the most populous city is Jacksonville. Florida's other major population centers include Tampa Bay, Orlando, Cape Coral, and the state capital of Tallahassee.

Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first documented European to make landfall in the region and named it La Florida (Spanish for "land of flowers"; [la floˈɾiða]), giving the territory its present name. Spain subsequently incorporated Florida into the Spanish Empire in the early 16th century. In 1565, it founded St. Augustine, the oldest continuously inhabited European-established settlement in the continental United States. The region was frequently coveted and attacked by Great Britain throughout the 18th century. Britain briefly gained control of Florida in 1763, but Spain recovered it in 1783 following the British defeat in the American Revolutionary War. Florida remained under Spanish rule until it was ceded to the United States in 1821, in exchange for U.S. recognition of Spanish sovereignty in Texas and the resolution of the border dispute along the Sabine River. Florida was admitted as the 27th state on March 3, 1845, and was the principal location of the Seminole Wars (1816–1858), the longest and most extensive of the American Indian Wars. The state seceded from the Union on January 10, 1861, becoming one of the seven original Confederate States, and was readmitted to the Union after the Civil War on June 25, 1868.

The Red River is a major river in the Southern United States. It was named for its reddish water color from passing through red-bed country in its watershed. It also is known as the Red River of the South to distinguish it from the Red River of the North, which flows between Minnesota and North Dakota into the Canadian province of Manitoba. Although once a tributary of the Mississippi River, the Red River now is a tributary of the Atchafalaya River, a distributary of the Mississippi that flows separately into the Gulf of Mexico. This confluence is connected to the Mississippi River by the Old River Control Structure.

The south bank of the Red River formed part of the US–Mexico border from the Adams–Onís Treaty (in force only in 1821), until the Texas Annexation and the Treaty of Guadalupe Hidalgo.

The Seminole Wars (also known as the Florida Wars) were a series of three military conflicts between the United States and the Seminoles that took place in Florida between about 1816 and 1858. The Seminoles are a Native American nation which coalesced in northern Florida during the early 1700s, when the territory was still a Spanish colonial possession. Tensions grew between the Seminoles and American settlers in the newly independent United States in the early 1800s, mainly because enslaved people regularly fled from Georgia into Spanish Florida, prompting slaveowners to conduct slave raids across the border. What began as small cross-border skirmishes became the First Seminole War, as Andrew Jackson led U.S. forces into Florida—despite Spanish objections—to pursue the Seminoles. Jackson's forces destroyed several Seminole, Mikasuki and Black Seminole towns, as well as captured Fort San Marcos and briefly occupied Pensacola before withdrawing in 1818. In 1819 the U.S. and Spain agreed to transfer Florida in the Adams–Onís Treaty; in return, the United States renounced its claims to Texas and fixed the boundary at the Sabine River.

The United States gained possession of Florida in 1821 and coerced the Seminoles into leaving their lands in the Florida panhandle for a large Indian reservation in the center of the peninsula per the Treaty of Moultrie Creek. In 1832 by the Treaty of Payne's Landing, however, the federal government under United States President Andrew Jackson demanded that they leave Florida altogether and relocate to Indian Territory (modern day Oklahoma) as per the Indian Removal Act of 1830. Those who refused to move resisted violently, leading to the Second Seminole War (1835–1842), which was by far the longest and most wide-ranging of the three conflicts. Initially, less than 2,000 Seminole warriors employed hit-and-run guerilla warfare tactics and knowledge of the land to evade and frustrate a combined U.S. Army and Marine force that grew to over 30,000. Instead of continuing to pursue these small bands, American commanders eventually changed their strategy and focused on seeking out and destroying hidden Seminole villages and crops, putting increasing pressure on resisters to surrender or starve with their families.

John Quincy Adams (/ˈkwɪnzi/ ; July 11, 1767 – February 23, 1848) was the sixth president of the United States, serving 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 served as a diplomatic minister and also as a member of the United States Congress representing Massachusetts in both chambers. He was the eldest son of John Adams, the second president, and First Lady Abigail Adams. Initially a Federalist like his father, he won election to the presidency as a member of the Democratic-Republican Party, and later, in the mid-1830s, became affiliated with the Whig Party.

Born in Braintree, Massachusetts, Adams spent much of his youth in Europe, where his father served as a diplomat. After returning to the United States, Adams established a successful legal practice in Boston. In 1794, President George Washington appointed Adams as the U.S. minister to the Netherlands, and Adams would serve in high-ranking diplomatic posts until 1801, when Thomas Jefferson took office as president. Federalist leaders in Massachusetts arranged for Adams's election to the United States Senate in 1802, but Adams broke with the Federalist Party over foreign policy and was denied re-election. In 1809, President James Madison, a member of the Democratic-Republican Party, appointed Adams as the U.S. minister to Russia. Multilingual, Adams held diplomatic posts for the duration of Madison's presidency, and he served as part of the American delegation that negotiated an end to the War of 1812. In 1817, President James Monroe selected Adams as his secretary of state. In that role, Adams negotiated the Adams–Onís Treaty in 1819, which transferred Florida to the United States, delineated the Sabine–Red–Arkansas–42nd parallel boundary, and formalized the U.S. renunciation of claims to Texas. He also helped formulate the Monroe Doctrine, which became a key tenet of U.S. foreign policy. In 1818, Adams was elected a member of the American Philosophical Society in Philadelphia.

Andrew Jackson (March 15, 1767 – June 8, 1845) was the seventh president of the United States from 1829 to 1837. He rose to fame as a U.S. Army general and served in both houses of the U.S. Congress. His political philosophy, which dominated his presidency, became the basis for the rise of Jacksonian democracy. His legacy is controversial: he has been praised as an advocate for working Americans and preserving the union of states, and criticized for his racist policies, particularly towards Native Americans. He was also the founder of, and first president from, the Democratic Party, which dominates American politics to this day along with the Republican Party.

Jackson was born in the colonial Carolinas before the American Revolutionary War. He became a frontier lawyer and married Rachel Donelson Robards. He briefly served in the U.S. House of Representatives and the U.S. Senate, representing Tennessee. After resigning, he served as a justice on the Tennessee Superior Court from 1798 to 1804. He purchased a plantation later known as the Hermitage, becoming a wealthy planter who profited off the forced labor of hundreds of enslaved African Americans during his lifetime. In 1801, he was appointed colonel of the Tennessee militia and was elected its commander. He led troops during the Creek War of 1813–1814, winning the Battle of Horseshoe Bend and negotiating the Treaty of Fort Jackson that required the indigenous Creek population to surrender vast tracts of the present-day U.S. states of Alabama and Georgia. In the concurrent war against the British, Jackson's victory at the Battle of New Orleans in 1815 made him a national hero. He later commanded United States forces during the First Seminole War against the Seminoles and other allied Native groups. This campaign was one of the factors that prompted Spain to negotiate the cession of Florida to the United States, which was finalized in the Adams–Onís Treaty of 1819, in exchange for United States renunciation of territorial claims. He briefly served as Florida's first territorial governor before returning to the Senate. He ran for president in 1824. He won a plurality of the popular and electoral vote, but no candidate won the electoral majority. With the help of Henry Clay, the House of Representatives elected John Quincy Adams as president. Jackson's supporters alleged that there was a "corrupt bargain" between Adams and Clay (who joined Adams' cabinet) and began creating a new political coalition that became the Democratic Party in the 1830s.

The Texas panhandle is a region of the U.S. state of Texas consisting of the northernmost 26 counties in the state. The panhandle is a square-shaped area bordered by New Mexico to the west and Oklahoma to the north and east. It is adjacent to the Oklahoma Panhandle, land which Texas previously claimed. The 1820 Missouri Compromise declared no slavery would be allowed in states admitted from the Louisiana Purchase above 36°30′ north latitude. Texas was annexed in 1845 from still more westerly land. The Compromise of 1850 removed territory north of this line from Texas, and set the border between the Texas Panhandle and the New Mexico Territory at the 103rd meridian west. The eastern border at the 100th meridian west was inherited from the Adams–Onís Treaty of 1819, which defined the border between the United States and New Spain. The Handbook of Texas defines the southern border of Swisher County as the southern boundary of the Texas Panhandle region.

Its land area is 25,823.89 sq mi (66,883.58 km), or nearly 10% of the state's total. The Texas Panhandle is slightly larger in size than the US state of West Virginia. An additional 62.75 sq mi (162.53 km) is covered by water. Its population as of the 2010 census was 427,927 residents, or 1.7% of the state's total population. As of the 2010 census, the population density for the region was 16.6 per square mile (6.4/km). However, more than 72% of the Panhandle's residents live in the Amarillo Metropolitan Area, which is the largest and fastest-growing urban area in the region. Despite being geographically the northernmost part of Texas, the Panhandle is distinct from the region commonly called "North Texas", which is to the south and east.

Jacksonville (US: /ˈdʒæksənˌvɪl/ JAK-sən-vil) is the most populous city proper in the U.S. state of Florida, located on the Atlantic coast of northeastern Florida. It is the county seat of Duval County, with which the city consolidated in 1968. It is the tenth-most populous U.S. city and the largest city in the Southeast, with a population of 949,611 at the official 2020 U.S. census. The Jacksonville metropolitan area, at over 1.76 million residents, is the fourth-largest metropolitan area in Florida and 38th-largest in the United States. City-county consolidation greatly increased Jacksonville's official population and extended its boundaries, placing most of Duval County's population within the new municipal limits; Jacksonville grew to 900 square miles (2,300 km). It is the largest city by total area, land and water, in the contiguous United States.

Jacksonville straddles the St. Johns River in the First Coast region of northeastern Florida, about 12 miles (19 kilometers) south of the Georgia state line (25 mi or 40 km to the urban core/downtown) and 350 miles (560 km) north of Miami. The Jacksonville Beaches communities lie along the adjacent Atlantic coast. The area was originally inhabited by the Timucua. During Spanish rule, several missions were established in the Jacksonville area; the most prominent locally was San Juan del Puerto on present-day Fort George Island, which served the Mocama Timucua. In 1564, the French founded the short-lived Fort Caroline near the mouth of the St. Johns River. During the brief period of British rule (1763–1783), a settlement developed at a narrow point on the river where cattle crossed, known as Wacca Pilatka to the Seminole and "Cow Ford" to the British. In 1822, a year after Spain ceded Florida to the United States under the Adams–Onís Treaty, in exchange for U.S. recognition of Spanish sovereignty in Texas, a platted town was established there and named for Andrew Jackson, the first military governor of the Florida Territory and the seventh president of the United States.

The Oregon boundary dispute or the Oregon Question was a 19th-century territorial dispute over the political division of the Pacific Northwest of North America between several nations that had competing territorial and commercial aspirations in the region.

Expansionist competition into the region began in the 18th century, with participants including the Russian Empire, Great Britain, Spain, and the United States. After the War of 1812, the Oregon dispute took on increased importance for diplomatic relations between the British Empire and the fledgling American republic. In the mid-1820s, the Russians signed the Russo-American Treaty of 1824 and the Russo-British Treaty of 1825, and the Spanish signed the Adams–Onís Treaty of 1819, by which Russia and Spain formally withdrew their respective territorial claims in the region, and the British and the Americans acquired residual territorial rights in the disputed area. But the question of sovereignty over a portion of the North American Pacific coast was still contested between the United Kingdom and the United States. The disputed area was defined as the region west of the Continental Divide of the Americas, north of Mexico's Alta California border of 42nd parallel north, and south of Russian America at parallel 54°40′ north. The British generally called this region the Columbia District and the Americans generally called it Oregon Country.
