What did America gain from the Adams-Onis Treaty?

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.

Under the Onís-Adams Treaty of 1819 (also called the Transcontinental Treaty and ratified in 1821) the United States and Spain defined the western limits of the Louisiana Purchase and Spain surrendered its claims to the Pacific Northwest. In return, the United States recognized Spanish sovereignty over Texas.

It gave control of Florida to the Americans.
