The main aim of colonial powers during the Age of Discovery was to expand their empires, acquire new territories, and exploit resources. European nations sought to establish trade routes to Asia and access valuable commodities like spices and silk. Additionally, they aimed to spread Christianity and enhance their political power. This era marked the beginning of significant global interactions, leading to the establishment of colonies in the Americas, Africa, and Asia. The motivations guiding colonial expeditions also included national rivalry and competition, culminating in an era of exploration, conquest, and the establishment of trade networks that significantly altered global demographics and economies.
