The Batwa Tribe, also known as the Twa, is one of the few pygmy groups in Africa. They have long occupied the mountainous region of the Bwindi Forest, where the rare mountain gorilla lives. The Batwa Tribe is one of the oldest groups continuously inhabiting Africa since earliest times. This makes them, like the San Tribe in Namibia, the earliest inhabitants in all of Africa. Both of these groups were initially hunter gatherers. When the Tutsi and Hutus were victims of the mass government genocide in 1994, the Batwa who lived in nearby villages lost over 10,000 of their own tribe who had not been targeted, but were casualties of the conflict. The remaining 20,000 Batwa in Rwanda were only a small percentage of the densely populated country. Competition for food and jobs forced their tribe to move elsewhere. They became a target for discrimination by other tribes. They had no land and were already marginalized. In Rwanda, the Tutsis were established as herders, and the Hutus were farmers. The Batwa had only their pottery skills to support them. They were poor and discouraged. Frustration and unemployment resulted in a high incidence of alcoholism.
