Question

It cleared the way for U.S. expansion south into Florida and west to the Pacific Ocean and officially put Florida into U.S. hands.

Answer 1

The Adams-Onís Treaty of 1819, which resulted from Andrew Jackson's incursion into Spanish Florida, transferred Florida to the U.S. for $5 million and also shaped future territorial expansion to the Pacific.

Step-by-step explanation:

The incident leading to U.S. expansion into Florida involved General Andrew Jackson, who crossed into Spanish-controlled East Florida to address conflicts with Native American tribes. Rather than providing an apology for this breach of Spanish sovereignty, Secretary of State John Quincy Adams negotiated what would become known as the Adams-Onís Treaty. Concluded in 1819, the treaty transferred control of Florida from Spain to the United States for $5 million, with Spain relinquishing its claim to Oregon and the U.S. temporarily renouncing its claim to Texas.

This strategic agreement not only secured Florida for the United States but also set the stage for American territorial expansion to the Pacific. It represented a significant step towards realizing the vision of Manifest Destiny, which encouraged the westward expansion of American influence and power in the 19th century.
