In which year did Portuguese explorer Bartholomeu Diaz round the Cape of Good Hope?

Bartholomeu Diaz rounded the Cape of Good Hope in 1487, making this the correct answer. His journey was significant as it represented the first European expedition to sail around the southern tip of Africa, which opened the sea route to Asia for subsequent explorers. Diaz’s expedition was a pivotal moment in the age of exploration, as it demonstrated the feasibility of a maritime route to the Indian Ocean, leading to increased trade and exploration by European powers in the years that followed. His successful navigation around the Cape provided valuable information for future explorers, including Vasco da Gama, who later used this maritime route to reach India.
