After losing their remaining South African lands in 1840, Mzilikazi and his tribe permanently settled in the southwest of present-day Zimbabwe in what became known as Matabeleland, establishing Bulawayo as their capital. Mzilikazi then organised his society into a military system with regimental kraals, similar to those of Shaka, which was stable enough to repel further Boer incursions. Mzilikazi died in 1868; following a violent power struggle, his son Lobengula succeeded him.
