Moses Austin laid the foundation for this colony in Texas during late 1820 and 1821, but died before he could get the families to go. So Stephen decided to help and make it possible. He went to San Antonio de Bexar and got an empressario contract for 300 families to go to Texas. All of the settlers had to agree to become loyal to the Mexicans, have good character, become catholic, and be able to fend for
themselves. The colony was very successful.
