Summary
The Adams-Onis treaty was signed in February 1819. It was negotiated by John Quincy Adams and the Spanish Minister to the United States. It gave Florida to the United States, and established the border between the United States and Spain. It also determined that Texas was on the Spanish side of the border. The boundary line of the Adams-Onís treaty determined the southern boundary (Red River) and most of the western boundary (100th Meridian) of the future state of Oklahoma.
The Adams-Onis Treaty settled a long border dispute between the U.S and Mexico. It was also known as the Transcontinental Treaty, or the purchase of Florida. It was considered a triumph of American Diplomacy. The treaty was signed at Washington, February 22, 1819, by John Quincy Adams, secretary of
state, and Luis de Onís, Spanish minister.
The ratification was postponed for 2 years because Spain was trying to keep ongoing cooperation with the
U.S because of the revolutions in South America. When the Treaty was signed, Congress ratified it immediately. However, after Spain stalled, there was some American Opposition. Henry Clay wanted Texas to be put on the American side, but this motion was defeated by the Senate.
The Treaty ended the first era of United States expansion by providing for the cession of East Florida, the abandonment of the fighting over West Florida and making a boundary with the Spanish province of Mexico that made Texas a part of Mexico, therefore stopping the uncertainty of the boundary of the Louisiana Purchase.
