Legislative Council of the Territory of Florida
The Legislative Council of the Territory of Florida, often referred to as the Florida Territorial Council or Florida Territorial Legislative Council, was the legislative body governing the American territory of Florida (Florida Territory) before statehood. The territory of Florida was acquired by the U.S. in 1821 under the Adams–Onís Treaty. Replacing the form of martial law that had existed in the territory since Florida was acquired, the U.S. Congress in 1822 established a territorial government consisting of a governor, secretary, thirteen-member Legislative Council, and judiciary, all of whom were appointed by the U.S. president.
West Florida
Because of disagreements with the Spanish government, American and English settlers between the Mississippi and Perdido rivers declared that area as the independent Republic of West Florida in 1810. (None of the short-lived Republic lay within the borders of the modern U.S. state of Florida; it comprised the Florida parishes of today's Louisiana.) Within months it was annexed by the United States, which claimed the region as part of the Louisiana Purchase of 1803. In 1819 the United States negotiated the purchase of the remainder of West Florida and all of East Florida in the Adams–Onís Treaty, and in 1822 both were merged into the Florida Territory.
