As a symbol for Texan independence and pride, the Alamo flag is a well-known relic immortalized through history and Hollywood. The flag draws on the Mexican Federal Flag with the tri-color green, white, and red fields. The eagle at the center of the Mexican flag is replaced with 1824.
The Mexican constitution of 1824 gave the people of Texas rights similar to those enjoyed at the time by the citizens of the United States, but every new Mexican government attempted to increase control over Texas. To call attention to this, Texans removed the coat of arms from the center of a Mexican flag, and replaced it with the date of the constitution. It was this banner that flew from the walls of the Alamo.
For 13 days, less that 200 Texans held off an army of more than 5,000 men. The Alamo fell on March 6, 1836. The Texans in the Alamo were fighting to protect the rights outlined in the Mexican constitution of 1824 and never knew that Texas had declared its independence 4 days earlier.
