Madison County, Tennessee: History
Madison County was formed in 1821, and named for founding father and president, James Madison. The county was part of lands the United States purchased from the Chickasaw in 1818. After Congressional passage of the Indian Removal Act of 1830, most Chickasaw were forced out of the state and west to Indian Territory beyond the Mississippi River.
Pinson Mounds, one of the largest Woodland period (c. 1–500 CE) mound complexes in the United States, is located in Madison County. It has the second-tallest earthwork mound in the United States.
