<span> It is believed that the first Dutch settlers came to South Africa in 1652. These settlers founded the city of Cape Town and over time developed a unique culture, language, and society, helping to form a unified Afrikaner population. Afrikaners, also formerly known as Boers, historically have been defined as those Afrikaans language-speakers of European especially Dutch descent who have inhabited Southern Africa since the 17th century.
