What effects did the missions have on native Americans?

The missions didn't help the Native Americans. Many were killed by the priests and put into mass graves ( the graves are still there), they were not allowed to practice their cultural rites or to speak native languages, and they were required to work at the mission. I think even worse than the mission system was the government Native American schools. Children were taken from their parents and tribe to live at the schools. They were not allowed to speak native languages or learn the traditional things about their tribe.
