The new missions were over from the nearest Spanish settlement, San Juan Bautista. Martín de Alarcón, who had been appointed governor of Texas in late 1716, wished to establish a way station between the settlements along the Rio Grande and the new missions in East Texas. Alarcón led a group of 72 people, including 10 families, into Texas in April 1718, where they settled along the San Antonio River. Within the next week, the settlers built mission San Antonio de Valero and a presidio, and chartered the municipality of San Antonio de Béxar, now San Antonio, Texas.
