Explanation:

Since the conquest of Mexico, Spain has formally considered Texas as its land, but has made no attempt to colonize Texas until 1689, when it became known that the French colony of St. Louis had ceased to exist four years after its founding. In 1690, Alonso de Leon led an expedition to East Texas, during which Catholic missionaries founded the first mission in the territory, but in the face of resistance from local residents, missionaries returned to Mexico.

In 1716 a number of missions and a presidio were opened, which aimed to establish a buffer between Spanish possessions and French Louisiana. Two years later, the first civilian settlement, San Antonio, was established in Texas.
