The Portuguese Empire began in 1415 with the conquering of Ceuta in North Africa under Prince Henry the Navigator. Key figures included Pedro Álvares Cabral, who discovered and claimed Brazil for Portugal, and Vasco de Gama, the first to sail directly from Europe to India. By the late 15th century, Portugal had established colonies and forts throughout Africa, India, and Southeast Asia, becoming the first global empire and pioneering globalization through its extensive colonial trading network. However, its power declined in the late 16th century after the crowns of Spain and Portugal were united under King Philip II of Spain, bringing new colonial rivals like the Dutch and English.
