The Tumbuka are a Bantu ethnic group living in Northern Malawi, Eastern Zambia and Southern Tanzania. Their God is called Chiuta, who is the Supreme Creator. The language of the Tumbuka is called chiTumbuka – the 'chi' in front of Tumbuka meaning 'the language of the' just like 'ki' in 'kiSwahili' or 'se' in 'seTswana'. A Tumbuka will call another watumbuka, meaning one of the tribe of Tumbukas.
In northern Malawi the Tumbuka are ruled by village chiefs. Since the 1700s chiefs from the Chikulamayembe Dynasty are traditional supreme leaders of the Tumbuka people there.
The World Almanac (1998) estimates approximately 2,000,000 Tumbuka speakers exist in the aforementioned three countries. Ethnologue estimates a total of 1,332,000 Tumbuka speakers, including 940,000 in Malawi and 392,000 in Zambia, with no Tumbuka presence listed for Tanzania.
