During the colonial period, the
Havu Mwami Hubert Sangara, who had been taken prisoner by
Kigeli IV Rwabugiri and raised in the
Kingdom of Rwanda, sought to consolidate control over the Numbi area, and with the support from the
Belgians, settled many
Banyarwanda in the area of the mineral-rich
cinq collines (five hills: Numbi, Lumbishi, Luzirandaka, Ngandjo and Shanje). Sangara's moves to bring the area under his control were resisted by the (Ba)tembo people who also sought control over the area. Spillover violence from the 1993 war in
Masisi Territory led to open conflict between the autochthonous
Tembo people and the
Banyarwanda who had previously lived in the same areas. Tembo fled the highlands, and the Banyarwanda achieved de facto local autonomy by recognizing the authority of
Mwami Raymond Sangara, an ethnic
Havu. Mining at Numbi was a significant source of revenue for the rebel group
Rally for Congolese Democracy (RCD) during the two Congo wars. A 2008 report from the NGO
International Peace Information Service claimed income from the Numbi mines likely made its way to a variety of armed groups, including the
PARECO,
FDLR, and
CNDP. As of 2012, several militia groups were active in the area, including Mai Mai
Nyatura, Mai Mai Kichiriko and the
Democratic Forces for the Liberation of Rwanda (FDLR). In 2020, a group of 120 Nyatura militia stationed in Numbi who had previously surrendered to government forces decided to take up arms again after being treated poorly for about two months. ==See also==
