USA HISTORY

Detailed explanation-1: -The United States now wanted control of Florida. Spain’s attempt to bring settlers to Florida failed, and by 1800 Spain’s control of Florida had weakened. Gaining control of Florida for the United States would mean gaining control of the Mississippi River. That was an important route for trade.

Detailed explanation-2: -In the early 1800s, Florida belonged to Spain. Slaves from Georgia would escape to Florida and Seminole Indians from Florida would raid Georgia farms. For these reasons the US wanted to acquire this territory.

Detailed explanation-3: -American settlers moved in and began to resist Spanish control. After years of border arguments, Spain finally agreed to cede the Florida Territory to the U.S. in 1819 by signing the Adams-Onis Treaty, signed by Spanish minister Luis de Onis and U.S. Secretary of State John Quincy Adams.

Detailed explanation-4: -In 1819, after years of negotiations, Secretary of State John Quincy Adams achieved a diplomatic coup with the signing of the Florida Purchase Treaty, which officially put Florida into U.S. hands at no cost beyond the U.S. assumption of some $5 million of claims by U.S. citizens against Spain.
