Portuguese trade began in the 15th century during the Age of Discovery, when Portugal sought new routes to Asia and Africa. The country established a network of trading posts and colonies, focusing on spices, gold, and sugar. Key locations included Goa in India and Angola in Africa, which became vital for the Portuguese economy. The Portuguese Empire expanded its influence through maritime exploration, leading to the establishment of trade routes that connected Europe, Africa, and Asia. This trade network facilitated the exchange of goods, cultures, and ideas, significantly impacting global commerce and contributing to the rise of European colonialism.
