Which Portuguese navigator led the first European expedition to sight the Cape of Good Hope?

The answer is Bartolomeu Dias, who is credited with leading the first European expedition to successfully round the Cape of Good Hope in 1488. This crucial milestone was significant for European exploration as it provided a sea route to the Indian Ocean, which was key for trade with Asia. Dias's exploration efforts not only advanced maritime navigation but also opened up new territories for European powers. His journey around the southern tip of Africa helped demonstrate that it was possible to reach the Indian Ocean from the Atlantic, paving the way for future explorers, including Vasco da Gama, who would later capitalize on these findings to establish a sea route to India.
