Spain's Religious Motives for Conquest in the Americas

Religion was a primary driver of Spanish expansion, intertwined with political and economic aims:

1. Evangelization Mandate: Spreading Catholicism to Indigenous peoples was viewed as a sacred duty—saving souls from "paganism."
2. Papal Authorization: The 1493 bull Inter Caetera (Pope Alexander VI) granted Spain exclusive rights to colonize and convert in the New World.
3. Moral Justification: Conquest was framed as a just war against idolatry; the Requerimiento demanded submission to Church and Crown.
4. Mission System: Franciscans, Dominicans, Jesuits accompanied expeditions to establish missions—centers of conversion, labor, and cultural transformation.
5. Religious Unity: Fresh from the Reconquista and Inquisition, Spain sought to impose Catholic orthodoxy uniformly, avoiding the Protestant fragmentation afflicting Europe.

These motives were inseparable from the pursuit of gold, land, and imperial glory—but the Crown genuinely invested vast resources in missionary activity.
