This flag was created by replacing the Eagle in the center of the Mexican tricolor with the year "1824", referencing the 1824 Constitution of Mexico, in support of which Texas was fighting. This was the first flag approved for use by rebel forces by a Texan legislative body. In 1835, the Texan provisional government approved the use of this flag for privateers preying on Mexican commerce.
It has often been said that the 1824 flag was flown by Texan forces at the Battle of the Alamo. However, this was never alleged until 1860, long after the battle had occurred. Modern writers have pointed out that the presence of the 1824 flag at the time and place of the battle is highly unlikely. A similar flag was flown at least briefly by Texan Tejano forces, featuring two black, six pointed stars in place of the date. It is likely that the actual "Alamo flag" referred to by accounts of the time was the Lone Star and Stripes, which had been depicted in use at earlier battles such as Goliad, and was widely referred to as the "Texian flag".
