The Battle of the Alamo (February 23 – March 6, 1836) was a pivotal event in the Texas Revolution.
 Following a 13-day siege, Mexican troops under President General Antonio López de Santa Anna launched an assault on the Alamo Mission near San Antonio de Béxar (modern-day San Antonio, Texas, United States), killing all of the Texian defenders.
 Santa Anna's cruelty during the battle inspired many Texians—both Texas settlers and adventurers from the United States—to join the Texian Army.
 Buoyed by a desire for revenge, the Texians defeated the Mexican Army at the Battle of San Jacinto, on April 21, 1836, ending the revolution.

The Adams–Onís Treaty 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; and also during the Latin American Wars of Independence.
 Florida had become a burden to Spain, which could not afford to send settlers or garrisons.
 Madrid decided to cede the territory to the United States through the Adams–Onís Treaty 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 US claims on parts of Spanish Texas west of the Sabine River and other Spanish areas, under the terms of the Louisiana Purchase.

The Long Expedition was an 1819 attempt to take control of Spanish Texas by filibusters.
 It was led by James Long who was accompanied by Jean LaFitte, James Bowie, and Ben Milam.
 Long's army successfully established a small independent republic government, known as the "Republic of Texas" being the first use of the sovereign name and also called the Long Republic (distinct from the later Republic of Texas created by the Texas Revolution).
 The expedition crumbled later in the year, as Spanish troops drove the invaders out.
 Long returned to Texas in 1820 and attempted to reestablish his control.
The Battle of Coleto, also known as the Battle of Coleto Creek, the Battle of the Prairie, and the Batalla del encinal del Perdido, was fought on March 19–20, 1836, during the Goliad campaign of the Texas Revolution.
 In February, General José de Urrea led a branch of the Mexican army up the Gulf Coast of Mexican Texas toward Goliad, where a large contingent of soldiers from the Texian Army were garrisoned under Colonel James W. Fannin.
 Simultaneously, Mexican president Antonio Lopez de Santa Anna led a larger force into the Texian interior, where on March 6 his troops won the Battle of the Alamo.
 After learning of the Alamo's defeat, Texian general Sam Houston ordered Fannin to retreat from Goliad and join the rest of the army in Victoria.
