The Cinco Ranch community goes back to before Texas became a republic. In the 1820s, pioneer Moses Austin was granted by the Spanish government the authority to settle 300 families in the valleys of the Brazos and Colorado rivers. He died before he was able to accomplish this, but his son Stephen F. Austin was able to complete his father's wishes, even under the newly established Mexican government. One of the men who moved into these 300 slots of land (each one over 4,000 acres/16km2) was Randolph Foster, whose land spread across Fort Bend and Waller counties and upon which wild horses, deer, Native Americans and buffalo lived.
