The main motivation behind the Spanish colonization of the Americas was the pursuit of wealth, particularly through the acquisition of gold and silver, and the spread of Christianity. Spanish explorers and conquistadors, driven by mercantilist ambitions and the desire for territorial expansion, sought to exploit the resources of the New World. Beyond economic gain, there was also a religious component, as the Spanish aimed to convert Indigenous peoples to Christianity, fulfilling their religious duty. This colonization resulted in significant cultural exchanges, though it also led to the exploitation and decimation of native populations.
