Why did Portugal and Spain colonize Latin America?

Portugal and Spain colonized Latin America primarily to expand their empires, gain access to valuable resources, and spread Christianity. The promise of wealth from gold, silver, and agricultural products motivated both nations to establish colonies. Additionally, the Treaty of Tordesillas in 1494 divided the New World between Spain and Portugal, facilitating their territorial claims and exploration efforts. This colonization also allowed them to exert political and cultural influence over indigenous populations.
