The reverse of the state seal features the six national flags that have flown over Texas: the Kingdom of France, the Kingdom of Spain, the United Mexican States, the Republic of Texas, the Confederate States of America, and the United States of America. At the center of the seal are the live oak and olive branches symbolizing strength and peace. They surround a shield featuring symbols of the Texas Revolution.

The upper half of the shield depicts the Alamo. The first and final battles of the Texas Revolution are depicted on the lower half. On the left stands the famous Gonzales "Come and Take It" Cannon. On the right is "Vince's Bridge" which "Deaf" Smith destroyed during the Battle of San Jacinto, an action credited as strategic to victory for the Texans. Above the shield is emblazoned the battle cry, "Remember the Alamo," and beneath it are the words, "Texas One and Indivisible." Atop, centered between the flags, proudly rests the Lone Star of Texas.
