Old Kachikau is the third most prominent capital of descendants of Botswana of Kgosi Sekgoma Letsholathebe (Ba-Sekgoma) in the Chobe District. Kgosi Letsholathebe ruled the Batawana from 1891 to 1906 at Tsau in the Ngamiland District. Letsholathebe was banished by the British colonial administration after serving a jail sentence from 1906 to 1912 in a Gaborone prison over a chieftainship squabble with Mathiba. After his release, Sekgoma first settled his people at Kabolabola Chobe National Park, before he relocated his capital to Kavimba village, where he died in 1914. It was Motshabi, Letsholathebe's sister who re-located the capital from Kavimba to Old Kachikau.
During Motshabi's time, the new capital soon attracted the interest of foreign colonial traders who operated thriving businesses amongst the Chobe people. Old Kachikau was an educational hub of the Chobe District before independence. Kachikau Central School even admitted students from Zambia. Old Kachikau was also a centre for WENELA, a South African based company that recruited manual workers. Old Kachikau was abandoned in 1958 when the area was flooded by the overflowing Chobe River.
