The Seminoles lived in virtual isolation in and around the Everglades for many years. They lived in open-sided structures called chickees, which were adapted to the swampy environment. They survived by hunting, gathering wild foods, and growing crops like corn, pumpkins, and potatoes. As white settlers began moving to south Florida, they established trading posts. The Seminoles sold animal hides and pelts to the traders and in turn bought cloth, guns, tools, and food staples. This way of life lasted into the twentieth century.
