Fort Gibson is a historic military outpost located in present-day Oklahoma. Established in 1824, it served as a key strategic point for the U.S. Army during the westward expansion and played a significant role in the Indian Removal Act. The fort was instrumental in maintaining peace between various Native American tribes and settlers. Today, Fort Gibson is preserved as a historical site, offering visitors a glimpse into 19th-century military life. The site features reconstructed buildings, artifacts, and educational programs that highlight its importance in American history, particularly in relation to the Trail of Tears and the Civil War.
