Question

Who used missions to spread Catholicism, establish control over the territory, and create a self-sufficient frontier? write like a 7th grader

Answer 1

The Spanish did. Spanish missionaries—especially Franciscan priests—set up missions in places like California, Florida, Texas, and New Mexico. The missions tried to convert Native Americans to Catholicism, help Spain claim and control the land, and run farms and workshops so each mission could be a self-sufficient frontier settlement.
