What were two changes the friars introduced in Spanish America

Great question! The two main changes the Friars brought to Spanish America was bringing and spreading methods of word and setting an example. As with most if not all other indigenous groups that came in contact with the Spanish conquest in the sixteenth century, the conquests made by Spain were successful in terms of global achievement: a religious power from a small country in Europe that governed and maintained control of a vast area of land for several centuries. In history there is no equal achievement.
