Austin became the capital of the Republic of Texas in 1839. Edwin Waller laid out the city and reserved a hill above the Colorado River for Capitol Square. That early decision established the public site where successive capitol buildings and their grounds later developed.
A state capital is a place where government works, and its location often records an old argument about distance, transportation, or political influence. Some capitals grew around a site deliberately reserved for public buildings. Others inherited the job from a territorial government. Several states moved their headquarters more than once before settling on a permanent home. The familiar name on a classroom map is therefore only part of the story. A river crossing, a donated parcel of land, or a need to move farther inland could matter as much as the size of a town. State archives, legislative histories, and capitol museums record those decisions and the buildings that followed them. A city's designation as capital and the completion of its statehouse may be separated by many years. The spelling distinction reflects that difference: a capital is the city, while a capitol is a government building. Keeping the city and its buildings distinct makes the sequence of moves, construction, and occupation easier to follow.
