Portuguese Empire

The Portuguese Empire was the first, the longest and last European colonial empire, existing between 1415 and 1999. It ushered the European Age of Discovery, achieving a global scale, controlling vast portions of the Americas, Africa and various islands in Asia and Oceania. It was one of the most powerful empires of the early modern period, while at its greatest extent in 1820, covering 5.5 million square km (2.1 million square miles), making it among the largest empires in history. Composed of colonies, factories, and later overseas territories, it was the longest-lived colonial empire in history, from the conquest of Ceuta in North Africa in 1415 to the handover of Macau to China in 1999.

In the wake of the Reconquista, Portuguese sailors began exploring the coast of Africa and the Atlantic archipelagos in 1418–1419, using recent developments in navigation, cartography, and maritime technology such as the caravel, with the aim of finding a sea route to the source of the lucrative spice trade. In 1488, Bartolomeu Dias rounded the Cape of Good Hope and Cape Agulhas, and in 1498 Vasco da Gama reached India. In 1500, Pedro Álvares Cabral, while on a voyage to India, reached what would later be Brazil. Over the following decades, Portuguese sailors continued to explore the coasts and islands of East Asia, establishing forts and factories as they went. By 1571, a string of naval outposts connected Lisbon to Nagasaki along the coasts of Africa, the Middle East, and South Asia. This commercial network and the colonial trade had a substantial positive impact on Portuguese economic growth (1500–1800) when it accounted for about a fifth of Portugal's per-capita income.
