Spanish missions in Louisiana

The Spanish missions in Louisiana were religious outposts in Spanish Louisiana (La Luisiana) region of the Viceroyalty of New Spain, located within the present-day U.S. states of Louisiana and East Texas.

They were established by Spanish missionaries for Indian Reductions of the local Native Americans.

Mission Nuestra Señora de los Dolores de los Ais
Mission Nuestra Señora de los Dolores de los Ais was named for the indigenous Ais people, a former local tribe.

It was established in 1716–1717 by the Domingo Ramón-St. Denis expedition, and ceased operations in 1773. Its site is in San Augustine, Texas

Mission San Miguel de Linares de los Adaes
Mission San Miguel de Linares de los Adaes was the fifth mission established in eastern Tejas in 1716–1717. The mission was also established by the Domingo Ramón-St. Denis expedition and was to serve the Adaes Indian village, just 20 mi west of the French fort at Natchitoches, Louisiana. At that time the Spanish claimed the Red River to be the eastern boundary of New Spain, so the mission was considered part of Spanish Texas, despite the fact that New France claimed the Sabine River as the western boundary of La Louisiane.

The mission was attacked by French soldiers in 1719 and was abandoned. Three years later, the Marquis de San Miguel de Aguayo, Governor of Coahuila and Tejas when they were part of the Viceroyalty of New Spain, reopened the mission, but at a location closer to the Presidio of Los Adaes. The mission remained open until 1773.
