When American settlers first arrived in Texas in 1821,

Texas history is complicated. After Spain acquired Louisiana, Americans were allowed to settle around St. Louis and later be considered for land grants in the northern province area called Texas. As early as 1803, Americans settled there. After the Mexican Revolution of 1824, the Mexican government needed settlers to protect it from foreign invasion, and they offered liberal land grants to anyone who would become citizens, accept the Catholic faith, and settle there.
