For many years adventurers from Spain and France had explored Texas. For about fifty years Spain had tried to civilize and Christianize the Indians in East Texas. Finally the Spanish government had abolished the missions and presidios. During the following fifty years, very little had been done toward colonization in Texas. In 1821, Texas was an almost uninhabited country, with the exception of savage Indians. The Anglo-Americans came and changed it into a great state.
