Texas is unique among the United States and takes great pride in the things that set it apart, and this love for independence is reflected in all the state's symbols. The Lone Star state features emblems emblazed with stars along with symbols of Texas' ecosystem and life.
The flag of Texas was adopted in 1839, when Texas was still a republic. When Texas became part of the United States, the flag carried over and became a state flag. The blue stands for loyalty, the red stands for bravery, and the white stands for purity. The star was originally a symbol of Texan solidarity during the struggle for independence from Mexico, and now represents all of Texas and its unity. This star is where the state nickname of the Lone Star state originates. The use of a single stripe each of white and red actually has its roots in an earlier failed revolution and republic (the Republic of Fredonia) that involved a truce between the local Native Americans and the new settlers, with the two bands representing the two groups in the truce. The flag holds deep significance for many residents of Texas, and is flown with pride throughout the state.
The state seal is two-sided, with the front used for official purposes and the reverse side used for decoration. The front bears an insignia of a star, of course, surrounded on either side by an olive branch and a live oak branch. Below it is inscribed "Republic of Texas". The reverse side is far more complex. The center is a shield divided into three parts, with the top part showing the Alamo, the bottom left showing a cannon from the Battle of Gonzales, and the bottom right showing Vince's Bridge. The shield is surrounded by the flags of 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 - all the nations that have at one point or another had control over Texas. The shield is crowned with another star along with a banner reading "Remember the Alamo", and below the rest of the seal is another banner reading "Texas One and Indivisible". In addition, the branches from the front of the crest appear here as well.
Texas' symbols all serve to attest to the state's long and complicated history and to its struggles for independence and unity, and to this day they are symbols of pride for many of the state's residents.
