The Fort Parker massacre, also known as the Fort Parker raid, was an event in which a group of Texian colonists were killed in an attack by a contingent of Comanche, Kiowa, Caddo, and Wichita raiders at Fort Parker on May 19, 1836. During the attack, Cynthia Ann Parker, then approximately nine years old, was captured and spent most of the rest of her life within the Comanche Nation, later marrying Chief Peta Nocona and giving birth to a son, Quanah Parker, who became a prominent leader of the Comanches and a war leader during the Red River War of 1874–75. Cynthia’s brother John Richard Parker was also captured and remained with the Comanches for six years before his release was negotiated. He was unable to readapt to Western society and chose to return to the Comanche Nation.
