The Lone Star Republic refers to the independent nation of Texas from 1836 to 1845. It was established after Texas declared independence from Mexico following the Texas Revolution. The republic was characterized by its struggle for recognition and its efforts to establish a stable government. During its existence, the Lone Star Republic faced various challenges, including economic difficulties and conflicts with Native American tribes. It sought annexation by the United States, which was achieved in 1845, leading to Texas becoming the 28th state. The Lone Star flag remains a symbol of Texas pride today.
