The two main reasons pushing Portuguese explorers to leave their own country and seek to expand their influence and presence around the world since the mid-fifteenth century were economic and religious motives. The Portuguese were seeking new trade routes and sources of wealth, particularly in Asia, as they were facing economic difficulties at home. Additionally, they were driven by a desire to spread Christianity and convert people to Catholicism, which was an important aspect of Portuguese culture and identity at the time.
