The Xhosa are a southern Nguni people who settled South Africa’s Eastern Cape region by around the 14th or 15th century, expanding under the royal line founded by the chief Tshawe. From the late 18th through the 19th century, they fought a long series of Cape Frontier Wars against expanding British and Boer settlement, among the longest sustained African resistance to European colonization.
IsiXhosa's click consonants weren't originally Xhosa: they were absorbed centuries ago from Khoisan languages as Xhosa speakers moved west, and today about 15% of Xhosa vocabulary traces back to that contact.
