Portugal spearheaded European exploration of the world and the Age of Discovery. Prince Henry the Navigator, son of King John I of Portugal, became the main sponsor and patron of this endeavour. During this period, Portugal explored the Atlantic Ocean, discovering the Atlantic archipelagos the Azores, Madeira, and Cape Verde; explored the African coast; colonized selected areas of Africa; discovered an eastern route to India via the Cape of Good Hope; discovered Brazil, explored the Indian Ocean, established trading routes throughout most of southern Asia; and sent the first direct European maritime trade and diplomatic missions to China and Japan.
