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.
Florida State Capitol
Tallahassee was named Florida's capital in 1824, midway between the then-largest cities in the state, St. Augustine and Pensacola. The first territorial government met in a log building. A capitol building was constructed in 1826 but never completely finished. It was torn down in 1839 to make room for the erection of the present structure, which was completed in 1845, just prior to Florida's entry into the United States as the 27th state. Several additions to the historic capitol have been made throughout the years. Frank Millburn made the first expansion in 1902 by adding the classical style dome. In 1923, Henry Klutho additions included two new wings and a marble interior. Finally, large wings for the House and Senate chambers were added to the north and south ends of the building in 1936 and 1947, respectively.
