The document summarizes the Adams-Onís Treaty of 1819 between the United States and Spain. It discusses the context around American expansionism following the War of 1812 and Latin American revolutions for independence from Spain. It outlines how Andrew Jackson's invasion of Spanish Florida raised tensions, and how Secretary of State John Quincy Adams' aggressive negotiation led to Spain ceding East Florida and relinquishing claims to Oregon territory in exchange for the US abandoning claims to Texas and paying Spain. The treaty established the US-Mexico border and had lasting effects.
