The primary motivation behind the exploration of the Americas was the search for new trade routes and resources. European nations, particularly from the late 15th century, sought to bypass the overland routes controlled by Middle Eastern and North African powers to access the lucrative spice and silk markets of Asia. Explorers like Christopher Columbus sought a western sea route, leading to the unexpected discovery of the New World. Additionally, the promise of wealth in the form of precious metals, fertile land for agriculture, and opportunities for colonization motivated adventurers and sovereigns alike, setting the stage for significant economic and cultural exchanges between Europe and the Americas.
