Born in Virginia and raised in southeastern Missouri, Austin served in the Missouri territorial legislature before moving to Arkansas Territory and later Louisiana. His father, Moses Austin, received an empresario grant from Spain to settle Texas. After Moses Austin's death in 1821, Stephen Austin won recognition of the empresario grant from the newly independent state of Mexico. Austin convinced numerous American settlers to move to Texas, and by 1825 Austin had brought the first 300 American families into the territory. Throughout the 1820s, Austin sought to maintain good relations with the Mexican government, and he helped suppress the Fredonian Rebellion. He also helped ensure the introduction of slavery into Texas despite the attempts of the Mexican government to ban the institution. He led the initial actions against the Karankawa people in this area.
