Why were the Spanish conquistadors like Cortes and Pizarro interested in north and south America?

The Spanish conquistadors, like Hernán Cortés and Francisco Pizarro, were primarily motivated by the pursuit of wealth, glory, and the spread of Christianity. They sought to exploit the rich resources of the Americas, particularly gold and silver, which promised immense wealth and power. Additionally, they aimed to expand Spanish territorial claims and influence, driven by the desire to convert Indigenous populations to Christianity. Their expeditions were fueled by the spirit of adventure and competition among European powers during the Age of Exploration.
