Final answer:
Christianity was used to dominate and convert native populations in the Spanish Empire's colonization of the Americas. Many Native Americans resisted conversion, and the lasting effect was the spread of Roman Catholicism.
Step-by-step explanation:
The Spanish Empire used Christianity as a means to dominate and convert the native populations of the Americas. They viewed their version of Christianity as a way to control and impose their beliefs on the native peoples. However, many Native Americans resisted conversion, as they saw Christianity as a threat to their own traditions and beliefs.
The lasting effect of Spanish Christianity in the Americas was the spread of Roman Catholicism, which became the dominant religion in much of the region. This had profound cultural, social, and political impacts on the native populations and shaped the development of colonial society.
