Burundi: The Kingdom and the Divide
An old monarchy in the hills of Central Africa, a Belgian colony, and an independence overshadowed by cycles of massacre between Hutu and Tutsi

A small country in the highlands
Burundi is a small, landlocked, intensely hilly country in the African Great Lakes region, on the north-eastern shore of Lake Tanganyika. It is one of the most crowded and one of the poorest countries in the world — more than 14 million people farming tiny plots on steep ground, with coffee and tea the main exports. Its population is divided, on paper, into Hutu, Tutsi and Twa, but all Burundians speak the same language, share the same religion and culture, and lived intermingled across the same hills. The distinction was historically as much about cattle, status and lineage as descent; colonial rule turned it into a fixed racial hierarchy, and post-independence politics turned it into a series of mass killings.

The kingdom
The Kingdom of Burundi took shape over the 17th and 18th centuries and grew into a substantial state ruled by a mwami drawn from the Ganwa, a princely class distinct from both Hutu and Tutsi. Its symbol was the sacred drum, Karyenda, tied to kingship and to the fertility of the land, and kept and beaten only in ritual. The kingdom was preserved, with its monarchy, under colonial rule. Its monarchy was looser than neighbouring Rwanda's, and Hutu and Tutsi identities within it were relatively fluid — a Hutu family that acquired cattle and status could, over generations, become Tutsi.
The lake is the second-deepest in the world, and its fish are an important source of protein in a country where almost every other scrap of land is farmed by hand.
Colonial rule and a hardened divide
Germany claimed Burundi in the 1890s and, after armed clashes forced the king to accept its authority, ruled through him. After the First World War, Belgium took over Ruanda-Urundi as a League of Nations mandate and governed it alongside the Belgian Congo. Belgian rule kept the monarchy but reorganised everything beneath it: it demanded labour and pushed coffee growing, and, influenced by the so-called Hamitic hypothesis that cast the Tutsi as a superior race, it ruled through Tutsi chiefs and favoured Tutsi for schooling and administrative posts. What had been a flexible social distinction became a rigid one, backed by paper.
The assassination that broke the country
Burundi moved toward independence differently from Rwanda, where a Hutu revolution overthrew the Tutsi monarchy. Here the nationalist party, UPRONA, was led by Prince Louis Rwagasore, the mwami's son and a genuinely popular figure across the divide. UPRONA won the 1961 elections, Rwagasore became prime minister — and two weeks later he was shot dead by a hired gunman, at the instigation of rival politicians. His death removed the one leader who might have held Burundi together.
Burundi became independent on 1 July 1962 as a monarchy, but it unravelled fast. A Hutu-led coup attempt in 1965 was crushed and followed by the killing of Hutu politicians. In 1966 the army abolished the monarchy, declared a republic, and installed a Tutsi-dominated military regime.
His son Ntare V, who briefly replaced him in 1966, was deposed within months and killed in 1972 — the end of a dynasty that had reigned for some three centuries.
1972, and the cycle of killing
In April 1972 a Hutu-led rebellion in the south killed, by missionaries' estimates, 800 to 1,200 people, most of them Tutsi. The regime's response was a systematic, months-long campaign to kill educated Hutu — students, teachers, civil servants, clergy, anyone with a secondary education or a government job. Somewhere between 100,000 and 300,000 Hutu were killed, and many thousands fled abroad. Known in Burundi as the Ikiza, "the catastrophe", it is widely classed as a genocide, and it locked Tutsi control of the state, army and economy in place for another 20 years while creating a large, embittered Hutu refugee population.
A further round of mass killing came in 1988. Under pressure, the government of Pierre Buyoya introduced reforms and, in June 1993, held Burundi's first genuinely democratic election. It was won by Melchior Ndadaye, a Hutu — who was assassinated by Tutsi army officers in October, barely three months into his term.
Civil war, and an uneasy peace
Ndadaye's murder set off Hutu massacres of Tutsi and army reprisals against Hutu — more than 100,000 dead by the end of 1993, by one UN-backed estimate — and a civil war that lasted about 12 years, between the Tutsi-dominated army and Hutu rebel movements. Around 300,000 people were killed. A regional peace process, begun under Julius Nyerere and completed under Nelson Mandela, produced the Arusha Agreement of 2000: an ethnic balance in the army, ethnic quotas in government, and power-sharing. The main rebel group, the CNDD-FDD, won elections in 2005, and its leader Pierre Nkurunziza became president. For a decade the formula held, and the ethnic question was largely contained.
The peace frayed in 2015, when Nkurunziza sought a third term that the opposition said the constitution and the Arusha deal forbade. Protests were crushed, a coup attempt failed, and the repression that followed — killings, disappearances, the closure of independent media, and a fresh wave of refugees — pushed Burundi back into authoritarian rule dominated by the mostly Hutu ruling party, the CNDD-FDD, and its youth militia. Nkurunziza died suddenly in 2020; his successor, Évariste Ndayishimiye, has kept the system in place.
What Burundi carries
Burundi entered the modern era with something Rwanda did not fully have — a monarchy that stood above the Hutu-Tutsi line, and, in Rwagasore, a leader who crossed it. Both were gone by 1966, and the country then spent four decades in a cycle of massacre and counter-massacre that the Arusha power-sharing formula finally interrupted. It remains one of the poorest and most tightly governed countries in the world, its politics still built around a divide that its own people's shared language and culture never really matched.
