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.
Congress changed the Legislative Council's structure several times in the 1820s and 1830s, gradually granting the territory more autonomy. Beginning in 1826, Council members were popularly elected rather than appointed by the president. In 1838, the Council became bicameral and was divided into a Senate and House of Representatives.
The Council was superseded by the General Assembly of the State of Florida after statehood was granted 1845.
The Council determined to rotate between the historical capitals of Pensacola, Florida and St. Augustine, Florida. The first legislative session was held at Pensacola on July 22, 1822; this required delegates from St. Augustine to travel 59 days by sea to attend. To get to the second session in St. Augustine, Pensacola members traveled 28 days over land. During this session, the council decided future meetings should be held at a half-way point to reduce the distance; eventually Tallahassee, site of an Apalachee settlement in the early 18th century, was selected as a half-way point between the former capitals of East and West Florida.
Dr. William H. Simmons and John Lee Williams of Pensacola were commissioned by the second Florida Territorial Council to select a central point between St. Augustine and Pensacola to serve as capital of the Florida Territory in 1823. The Florida Territorial Council commissioned John Bellamy, a Monticello, Florida planter, to build Bellamy Road.
