Prince Henry of Portugal – also called Prince Henry the Navigator – began Portugal’s great age of exploration. From about 1419 until his death in 1460, he sent several sailing expeditions down the coast of Africa.4 In 1481, King John II of Portugal began sending expeditions to find a sea route around the southern shores of Africa. Many explorers made several attempts. It was Bartolomeu Dias who was the first to round Africa and make it to the Indian Ocean in 1488. But he was forced to head back to Portugal before he could make it to India.
