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.
History of Leon County, Florida
On March 30, 1822, the United States merged East Florida and part of West Florida into the Florida Territory. Originally part of Escambia and later Gadsden County, Leon County was created in 1824. It was named for the Juan Ponce de León, Spanish explorer who was the first European to reach Florida.Leon County in the 1820s and 1830s was the destination of a number of northern planters. Besides the aforementioned R.K. Call and John Branch, names such as Francis W. Eppes, William Bailey, the Chaires brothers, the Bradford brothers, George Taliaferro Ward, and many others began large cotton plantations in Leon County. At the center of what was then called Middle Florida, there was much less population than in East Florida and West Florida, and no problem with the memories of the more lenient treatment of slaves under Spain. Building a plantation, slave-based economy in Middle Florida was much easier.
