Native Burundians belong to one of the three major ethnic groups in Burundi: the Hutu, Tutsi, and Twa peoples. The historical origins of ethnic differentiation between Hutu and Tutsi are disputed, however members of both groups consider themselves distinct.The relations between the indigenous ethnic groups in Burundi have greatly varied depending on the historical context or era. Generally, the distinctions have always existed, yet at certain periods they have produced greater violence than others. The ethnic dynamics between Hutus and Tutsis have especially shaped Burundian history and politics and have become a major object of study by scholars. Today, the Hutu are the largest ethnic group in Burundi, representing approximately 85 percent of Burundians.Under Colonial rule and then Burundi's Tutsi-dominated postcolonial government between 1965 and 2001, the Hutu population was marginalized and subordinated to the Tutsi elites. Since the end of the Burundian Civil War (1993–2005), however, Hutus have been dominant in political life. The Tutsi represent approximately 14 percent of the national population. Historically, the Tutsi dominated political institutions in Burundi, including the nation's monarchy, then their favoritism by colonial governments, and even after independence, the subsequent dictatorial regimes of Michel Micombero (1966–76), Jean-Baptiste Bagaza (1976–87), and Pierre Buyoya (1987–93) were dominated by Tutsi elites which often discriminated against the Hutu majority. The Twa make up around 1 percent of Burundi's population. As an ethnic group, they have links to the pygmy peoples of the Democratic Republic of the Congo. Nowadays, they often work as unskilled laborers. The Twa have historically been economically and politically marginalized by the other two ethnic groups. They are often disproportionately poor and suffer from legal discrimination.
