Bartolomeu Dias was commissioned by King John II of Portugal to explore the southern coast of Africa in search of a sea route to India. In the late summer of 1487, Dias departed with a fleet of three ships, navigating the often treacherous waters of the Atlantic Ocean. After several months of sailing, he successfully rounded the Cape of Good Hope, which he initially referred to as the 'Cape of Storms' due to the tempestuous weather he encountered. However, following his expedition, it was renamed to reflect its newfound significance as a passage to the riches of the East.

Upon reaching Mossel Bay, Dias and his crew made contact with local Khoikhoi tribes, marking an important moment of interaction between European explorers and the indigenous peoples of South Africa. The landing at Mossel Bay not only provided a rest stop for Dias' fleet but also showcased the rich diversity of the region and its inhabitants. During their brief stay, the crew replenished their supplies before continuing their journey further east along the African coast.

Dias' expedition laid the groundwork for future voyages, most notably those of Vasco da Gama, who would eventually reach India. The exploration of the southern tip of Africa opened up new possibilities for trade and navigation, establishing a European presence in the Indian Ocean and altering the course of maritime history. While Dias did not reach India himself, his navigational successes were pivotal in paving the way for the expansion of Portuguese influence into Asia.
