United States territorial acquisitions
West Florida was declared to be a U.S. possession in 1810 by President James Madison after the territory had declared its independence from Spain. Madison ordered the U.S. Army to take control. Six weeks later, the army entered and occupied the capital, St. Francisville, putting an end to the republic after 74 days of independence. Spain did not relinquish its claim to sovereignty (see West Florida Controversy) until ratification of the Adams–Onís Treaty. General Andrew Jackson personally accepted the delivery of West Florida from its Spanish governor on July 17, 1821.
Legislative Council of the Territory of Florida
One of the requirements for a United States territory to become a state of the Union is that its constitution be approved by the United States Congress. In order to fulfill that requirement, an Act was passed by the Florida Territorial Council in 1838, approved by Governor Richard Keith Call, calling for the election of delegates in October 1838 to a convention to be held at St. Joseph, Florida. The delegates were to draft a constitution and bill of rights for the Territory of Florida. The Constitutional Convention convened on December 3, 1838, with Robert R. Reid presiding as president and Joshua Knowles secretary. The work of the Convention was carried out by eighteen committees, whose members were familiar with that particular area of government. The process was a relatively simple one, since they used the constitutions of several other Southern states as models. Only on the subject of banking did much debate take place. The Convention adjourned "sine die" on January 11, 1839.
