USA HISTORY

Detailed explanation-1: -Minister Onís and Secretary Adams reached an agreement whereby Spain ceded East Florida to the United States and renounced all claim to West Florida. Spain received no compensation, but the United States agreed to assume liability for $5 million in damage done by American citizens who rebelled against Spain.

Detailed explanation-2: -Florida had become a burden to Spain, which could not afford to send settlers or garrisons, so the Spanish government decided to cede the territory to the United States in exchange for settling the boundary dispute along the Sabine River in Spanish Texas.

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.
