Nande-Hutu rivalry

"Hutu-Nande rivalry goes back a long way in North Kivu. The Nande outnumber the Hutu at the provincial level and are an extremely affluent community of traders. The Nande started populating the northern part of the Kivus, bordering Uganda, probably two centuries ago. The territories of Beni and Lubero in the Grand Nord are almost exclusively inhabited by Nande and the community, especially in Lubero Territory is known for its tendencies to keep business competitors out, through sophisticated dumping practices and covert support for various militia, such as the Mayi Mayi and the FDLR. The RCD never managed to take control of the Grand Nord and many Nande-traders have settled in other provinces, but also in Rutshuru where Hutu-resentment against their wealth, business monopolies and practices are longstanding issues."
