how did florida become part of the united states

Florida became part of the United States through a series of events known as the Adams-Onís Treaty, also called the Transcontinental Treaty. Here is a brief overview of how Florida became part of the United States:

1. Spanish control: Florida was originally under Spanish control since the early 16th century when Spanish explorer Juan Ponce de León claimed it. However, Spain struggled to maintain control over the territory, and it became a haven for pirates and escaped slaves.

2. American interest: Due to its strategic location and the desire to expand American influence, the United States became interested in acquiring Florida. Throughout the late 18th and early 19th centuries, American settlers moved into the region, leading to tensions with the Spanish authorities.

3. Andrew Jackson's invasion: In 1818, Andrew Jackson, a future U.S. President, led an invasion into Florida, known as the First Seminole War. Although his actions were controversial, it put pressure on Spain to consider negotiating the transfer of the territory.

4. Adams-Onís Treaty: In 1819, the United States and Spain signed the Adams-Onís Treaty, which officially ceded Florida to the United States. In exchange, the United States agreed to relinquish its claims on Texas and paid off some Spanish debts.

5. Transition to American control: Florida formally became a U.S. territory in 1821, with General Jackson serving as its first military governor. It remained a territory until 1845 when it was admitted as the 27th state of the United States.

Overall, the acquisition of Florida was a combination of American settlement, military actions, and diplomatic negotiations, leading to its eventual transfer from Spanish to American control.
