The colours and the stripes and star symbols in the Texas flag were derived from those of the U.S. flag. The present state flag was originally adopted on January 25, 1839, as the second national flag of the Republic of Texas.
The red and blue of the state flag are the same colors used in the United States flag. The red, white, and blue of the state flag represent, respectively, bravery, purity and loyalty.
Over the years of fighting and hardship, Texas has come to have an identity of its own and that can be seen in the colors of the Flag. In 1839, the Congress of Texas voted to change the colors of the flag from a yellow star in the middle of a dark blue background to what we see today.
The Texas state flag which is the official US state flag of Texas was officially adopted on January 25, 1839. It features a single white star, and three bands of red, white, and blue.
