The Daughters of the Republic of Texas (DRT) is a lineal association dedicated to perpetuating the memory of the founding families and soldiers of the Republic of Texas. The Daughters of the Republic of Texas is best known for its former role as caretakers of The Alamo. In early 2015, Texas Land Commissioner George P. Bush officially removed control of the Alamo to the Texas General Land Office. The DRT were also the custodians of the historic French Legation Museum until 2017, which is owned by the State of Texas and is now operated by the Texas Historical Commission. In addition, they operate a museum in Austin on the history of Texas.

The Alamo is a historic Spanish mission and fortress compound founded in the 18th century by Roman Catholic missionaries in what is now San Antonio, Texas, United States. It was the site of the Battle of the Alamo in 1836, a pivotal event of the Texas Revolution in which American folk heroes James Bowie and Davy Crockett were killed. Today it is a museum in the Alamo Plaza Historic District and a part of the San Antonio Missions World Heritage Site.
