The Kingdom of Great Britain captured Cape Town in 1795 during the Napoleonic Wars and permanently acquired South Africa from Amsterdam in 1814. The first British immigrants numbered about 4,000 and were introduced in 1820. They represented groups from England, Ireland, Scotland, or Wales and were typically more literate than the Dutch. The discovery of diamonds and gold led to a greater influx of English speakers who were able to develop the mining industry with capital unavailable to Afrikaners. They have been joined in more subsequent decades by former colonials from elsewhere, such as Zambia and Kenya, and poorer British nationals looking to escape famine at home.
