Answer:
The settlement of Austin's colony from 1821 to 1836 has been called the most successful colonization movement in American history. Many of the historical events of Southeast Texas owe their origin to this colony. Fort Bend County was one of the most heavily populated areas of the colony.
Stephen F. Austin's father, Moses, laid the foundation for this colony in Texas during late 1820 and 1821, but died before being able to implement his plans. Stephen, although hesitant at first, decided to finish what his father had begun. Austin travelled to San Antonio de Bexar, where he was declared the rightful heir to his father's grant. Austin was issued an empressario contract to settle three hundred families in Spanish Texas. The Spanish demanded the settlers be, among other things, loyal to the offical government and religion of Spain. Both the government and Austin realized the necessity of having colonists of reputable character, and both made this a prerequisite for immigration. Soon after gaining this contract, the eleven-year war for Mexican Independence ended successfully, and the new Mexican government affirmed Austin's contract to settle Texas with families from the United States.
