In the early 19th century Texas was a Northern province of Mexico, then under the thumb of Spain. Stephen F. Austin began leading settlers into Texas in 1821 with the intent on starting a colony there. Mexico, however, gained its independence from Spain that very year. As thousands of Americans poured into Texas, many seeking a new start for themselves, Mexico began to clamp down on the migration and eventually began to pass measures that many Americans thought to be severe restrictions on their freedoms, one of which was a ban on slavery. Texas was soon in a state of revolt by the mid-1830’s and formally declared its independence from Mexico in 1836.
