Answer:
The Spanish Colonial era in Texas began with a system of missions and presidios, designed to spread Christianity and establish control over the region.
Step-by-step explanation:
The California missions began in the late 18th century as an effort to convert Native Americans to Catholicism and expand European territory. There were 21 missions in all, lasting from 1769 until about 1833. Its purpose was to provide military support for the mission and later settlements until these communities could support themselves. The main purpose of a presidio was to protect the colonists from Indian attacks. Presidio soldiers were also expected to bring back any natives who ran away from the mission.
