History of Florida
In 1810, parts of West Florida were annexed by proclamation of President James Madison, who claimed the region as part of the Louisiana Purchase. These parts were incorporated into the newly formed Territory of Orleans. The U.S. annexed the Mobile District of West Florida to the Mississippi Territory in 1812. Spain continued to dispute the area, though the United States gradually increased the area it occupied.Seminole Indians based in East Florida had been raiding Georgia settlements, and runaway American slaves were their allies; Negro Fort, an abandoned British fortification in the far west of the territory, was manned by both Indians and blacks. The United States Army would lead increasingly frequent incursions into Spanish territory, including the 1817–1818 campaign against the Seminole Indians by Andrew Jackson that became known later as the First Seminole War. The United States now effectively controlled East Florida. Control was necessary, according to Secretary of State John Quincy Adams, because Florida had become "a derelict open to the occupancy of every enemy, civilized or savage, of the United States, and serving no other earthly purpose than as a post of annoyance to them." Florida had become a burden to Spain, which could not afford to send settlers or garrisons. Madrid therefore decided to cede the territory to the United States through the Adams–Onís Treaty, which took effect in 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.
