Which answer best explains how Florida became a U. S. territory?

March 3, 1845

England wanted to expand its colonies and began to threaten Florida in the 1700's, attacking St. Augustine many times. England, France and Spain were all fighting with each other in several parts of the world in the pursuit of growing their colonies. This conflict was known as both the Seven Years War and the French and Indian wars. In 1763, the treaty of Paris was signed by England, France and Spain and it resulted in England gaining the Florida Territory. But, when England formally recognized the colonies independence (as the united states) in 1783, the Florida territory was returned to Spain without clear definition of its boundaries. When we made the Louisiana Purchase from France, Florida was still without clear boundaries! How did our government finally get Florida and make it our 27th state?

With numerous boundary disputes, Spain's claim to Florida grew shaky. 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 the U. S. Secretary of State John Quincy Adams. More settler arrived and Tallahassee became the capital. Florida was admitted to the Union in 1845.
