The Taensa migrated as a result of Chickasaw and Yazoo hostilities, first lower down the Mississippi River. In 1715, protected by the French, they migrated to lands near the now eponymously named Tensas River near Mobile, Alabama. When the French ceded Mobile and their other territory east of the Mississippi River to the British in 1763, following their defeat in the Seven Years' War, the Taensa and other small tribes returned to Louisiana, settling near the Red River. They numbered about 100 persons in 1805. They later moved south to Bayou Boeuf and later still to Grand Lake, "after which the remnant disappear from history."
