Final answer:
During the Age of Discovery, explorers set out for unknown lands to seek wealth and fame for their home countries, spread Christianity and counter the influence of Islam, and expand their nation's influence and establish new trade routes.
Step-by-step explanation:
During the Age of Discovery, explorers had various motivations for setting out to unknown lands. One common reason was the desire to seek wealth and fame for their home countries. As rumors about new lands rich in gold and silver circulated in Western Europe, monarchs sponsored expeditions to find these riches and increase their power.
Additionally, some explorers were driven by their strong religious beliefs and the desire to spread Christianity and counter the influence of Islam. Explorers like Prince Henry the Navigator of Portugal saw their voyages as an opportunity to make converts and bring salvation to new lands.
Overall, the main motivations during the Age of Discovery were God, glory, and gold. Explorers sought to expand their nation's influence, acquire wealth, establish new trade routes, and spread their religious beliefs.
