Why do you think it was common for explorers to work for king and queens of different countries?

Explorers often worked for kings and queens because monarchies sought to expand their territories, wealth, and influence through exploration. By sponsoring expeditions, rulers could claim new lands, access valuable resources, and enhance their prestige. Additionally, explorers provided detailed maps and information about new regions, which were crucial for trade and military strategy, further solidifying the monarch's power and economic interests. This symbiotic relationship benefited both the explorers, who received funding and protection, and the monarchs, who gained new opportunities for expansion.
