The Lone Star Flag is the official flag of the state of Texas. It features a single white star on a blue vertical stripe, with horizontal stripes of white and red. The design symbolizes Texas' pride and independence, reflecting its history as an independent republic before joining the United States. Adopted in 1839, the flag's colors represent different ideals: blue stands for loyalty, white for purity, and red for bravery. The Lone Star itself is a symbol of Texas' unity and independence, often associated with the state's motto, "The Lone Star State."
