The Fort McKavett State Historic Site is a former United States Army installation located in Menard County, Texas. The fort was first established in 1852 as part of a line of forts in Texas intended to protect migrants traveling to California. The fort was deemed unnecessary and abandoned in 1859 and was occupied by settlers. From 1861 to 1863, during the American Civil War, the fort became an outpost of Confederate forces on the Texas frontier until they left for other theaters of the war. When the US Army returned to Texas in the later 1860s, the fort was reoccupied and rebuilt, and became a base for the "Buffalo Soldier", or all-African American, 24th Infantry and 9th Cavalry Regiments.
