From Texas Public Radio:
On March 5, 1731, Spanish friars essentially handed the keys to San Antonio’s missions to the Native American families who lived there. Just four days later, 56 residents from the Spanish archipelago of the Canary Islands landed in San Antonio, sent by Spain’s King Felipe the Fifth to establish the first official government in the province of Texas. And with that, thousands of years of Native American history in San Antonio began to disappear.
