Rwanda

The earliest known inhabitants of the territory of present-day Rwanda were Twa hunter-gatherers, who lived in the region's montane forests well before the agricultural settlement of the area. From roughly the first millennium of the common era, Bantu-speaking cultivators settled the hills of the Great Lakes region, gradually clearing forest for sorghum, beans, and bananas, while pastoralists with long-horned cattle established herding economies on the same landscape. Over centuries these populations coalesced into the social categories later recorded as Hutu, Tutsi, and Twa, distinctions that combined occupation, lineage, and clientship rather than fixed ethnicity in the modern sense.

By the seventeenth and eighteenth centuries a centralised Kingdom of Rwanda had emerged on the central plateau under the Nyiginya dynasty, ruled by a mwami (king) whose court at Nyanza administered a system of cattle clientship known as ubuhake and a parallel land tenure called ubukonde. Successive monarchs, notably Kigeli IV Rwabugiri in the late nineteenth century, expanded the kingdom's frontiers, tightened administrative control over outlying regions, and reinforced hierarchies among cultivators, herders, and the royal lineage. When European explorers reached the interior in the 1890s, they encountered one of the most tightly organised polities in the African Great Lakes.

Rwanda was claimed by the German Empire in 1885 and incorporated into German East Africa, with colonial authorities ruling indirectly through the existing court. After Germany's defeat in the First World War, the League of Nations assigned the territory, joined with Burundi as Ruanda-Urundi, to Belgium as a mandate in 1922; it became a United Nations trust territory under continued Belgian administration after 1946. Belgian rule formalised and racialised the Hutu and Tutsi categories, issuing identity cards in 1933 and channelling administrative posts disproportionately to Tutsi notables, which entrenched grievances that surfaced in the late 1950s.

The Hutu Revolution of 1959, the abolition of the monarchy in 1961, and a referendum the same year produced a Hutu-led republic, and Rwanda achieved formal independence on 1 July 1962 under President Gregoire Kayibanda. A 1973 coup brought Major General Juvenal Habyarimana to power; his single-party regime governed until international and domestic pressure forced moves toward multiparty politics in the early 1990s. From October 1990, the Tutsi-dominated Rwandan Patriotic Front, based in Uganda, waged a civil war against the government, and the Arusha Accords of 1993 attempted a power-sharing settlement that collapsed when Habyarimana's plane was shot down on 6 April 1994.

The genocide that followed killed an estimated 500,000 to 800,000 Tutsi and moderate Hutu over roughly one hundred days before the Rwandan Patriotic Front captured Kigali in July 1994 and ended the killings. The new government, led from 2000 by Paul Kagame, oversaw mass returns of refugees, the gacaca community courts, and military involvement in the wars in neighbouring Zaire (later the Democratic Republic of the Congo). A new constitution adopted in 2003 established the current institutional order, and amendments in 2015 extended presidential term limits.

Present-day Rwanda is a unitary presidential republic with a bicameral parliament, a member of the African Union, the East African Community, and the Commonwealth of Nations, governed under the 2003 constitution as subsequently amended.
