Who were the Spaniards leader?

The Spaniards during the age of exploration and conquest were often led by notable figures such as Hernán Cortés, who conquered the Aztec Empire, and Francisco Pizarro, who led the conquest of the Inca Empire. In a broader political context, King Ferdinand II of Aragon and Queen Isabella I of Castile were key monarchs who united Spain and sponsored explorations, including Christopher Columbus's voyage in 1492. Their leadership significantly shaped Spain's colonial ambitions in the Americas.
