Portuguese Colonialism refers to the period when Portugal established overseas territories from the 15th to the 20th century. It began with the Age of Discovery, during which explorers like Vasco da Gama sought new trade routes and lands. Portugal claimed territories in Africa, Asia, and South America, notably Brazil, Angola, and Goa. The Portuguese Empire was characterized by trade, resource extraction, and cultural exchange. The colonizers often imposed their language, religion, and customs on indigenous populations. This legacy has influenced the cultures of former colonies, contributing to the spread of Portuguese as a global language and the practice of Catholicism.
