The Adams-Onis Treaty
By:Caleb Rain

Thesis

In the early 1800s, a heated debate was taking place between the United States and Spain about the legitimacy of Napoleon’s sale of the Louisiana territory in 1803 and the exact boundaries of the Louisiana Purchase. Negotiations were deadlocked until 1817, when Andrew Jackson invaded Florida.This invasion intimidated spain’s prime minister into signing the Adams-Onis Treaty.  This treaty finalized the Louisiana Purchase, led to the reannexation of Texas, and set the stage for the conquest of California and the Southwest by the United States in the mid 1800s.
