How did Spanish policy regarding American Indians change during the late 1700s?

During the late 1700s, Spanish policy towards American Indians evolved to emphasize assimilation and integration rather than outright conquest. The Spanish began to establish missions and presidiOS aimed at converting Native Americans to Christianity and integrating them into colonial society. However, this period also saw increased tensions and conflicts as settlers encroached on Native lands, leading to a more complex relationship characterized by both cooperation and resistance. Overall, Spanish policies reflected a shift towards a more paternalistic approach, attempting to control and "civilize" Indigenous populations while navigating the challenges of colonial governance.
