What are the benefits from the Francisco Pizarro voyage?

Francisco Pizarro's voyages led to the Spanish conquest of the Inca Empire, resulting in significant territorial expansion for Spain in South America. This conquest facilitated the influx of vast amounts of gold and silver into Spain, greatly enhancing its wealth and power. Additionally, it initiated cultural exchanges and the spread of Christianity among Indigenous populations, profoundly impacting the region's Demographics and social structures. However, these benefits came at a high cost, including the exploitation and suffering of Indigenous peoples.
