Bartholomeu Dias's expedition was significant because it was the first European expedition to successfully round the southern tip of Africa, now known as the Cape of Good Hope. This opened up a new sea route to Asia, which would eventually lead to the establishment of European trade routes and colonial empires in the region. Dias's expedition also paved the way for future explorers, such as Vasco da Gama, to navigate these waters and further expand European influence in Asia.
