Tanganyika, Fizi Territory

Tanganyika is one of the four sectors of Fizi Territory in South Kivu Province, located in the eastern region of the Democratic Republic of the Congo. Spanning approximately 2,100 square kilometers, it ranks as the third-largest sector in the territory, following Lulenge. The sector derives its name from Lake Tanganyika, which borders it to the east and forms a natural boundary with Burundi. The name "Tanganyika" is rendered Tangani'a in Kibembe.

Tanganyika occupies the northeastern extremity of Fizi Territory. It is bordered to the north by the Ambaulu River, separating it from the Bavira Chiefdom in Uvira Territory; to the southeast by the Lweba River, which divides it from Mutambala; and to the southwest by Lulenge and Itombwe of neighboring Mwenga Territory. As of 2014, the sector had an estimated population of 284,916. It is administratively subdivided into five groupements: Babungwe-Nord, Balala-Nord, Basimukuma-Nord, Basilotcha, and Basimunyaka-Nord. The sector is predominantly inhabited by Babembe, who are indigenous to the area and constitute the majority population in the plains and middle plateaus. Other indigenous communities include the Bazoba, alongside smaller populations of Bafuliiru, Bashi, Barega, Banyamulenge, Banyidu, and Barundi. The local economy is primarily based on agriculture and livestock farming.

Tanganyika has been profoundly affected by the First and Second Congo Wars, which significantly disrupted the region and gave rise to ongoing insecurity characterized by armed conflict and localized violence.
