Burundi's history: a kingdom that drew its own frontiers

How the kingdom of Burundi took shape

The first people recorded in the region were the Twa, hunter-gatherers. Britannica dates the arrival of Hutu farmers to about 1000 CE; the Wikipedia article on the kingdom says Bantu farmers came from about the 11th century, and that pastoralists followed in waves. The valleys and hills became a patchwork of farmers, fishermen and foragers, and the local dynasties that formed among them gathered, over time, around two political centres, one in the north and one in the south.

When the kingdom began is disputed. Britannica and the BBC's timeline place the emergence of the state in the 16th century. The Wikipedia article on the kingdom gives 1680 as the commonly accepted founding date, under a first mwami, Ntare I, who unified the two centres. Burundian oral history tells the founding in more than one version, and in all of them Ntare brings rain and ends a famine. The Kanyaru cycle has his royal clan come from Rwanda; the Nkoma cycle has its founders migrate from Buha, in what is now the Kigoma Region of Tanzania. The Nkoma traditions are found across the country while the Kanyaru ones are local and official, and scholars lend the Nkoma version more weight.

Who ruled whom inside the kingdom

The ruler was the mwami, and between him and everyone else stood the ganwa, a princely class of potential heirs. Over time the royal clan became a group apart, neither Tutsi nor Hutu, which allowed it to hold the loyalty of both. Four ganwa lineages, the Bezi, Batare, Bataga and Bambutsa, each traced their origin to a king, and their rivalry was one of the main sources of conflict in the kingdom. Before colonisation the state was decentralised: on average about 220 noble lineages held power, and a ganwa could govern a fief as he pleased provided he paid taxes and sent troops in wartime.

Identity was less fixed than it later became. Britannica describes Tutsi as traditionally cattle owners and Hutu as farmers, and notes that a rich Hutu could be counted as Tutsi and a poor Tutsi as Hutu. The Wikipedia country article records Hutu farmers who acquired cattle being granted Tutsi status, some of them becoming advisers to the ganwa, and concludes that regional ties and power struggles mattered more in politics than ethnicity. Both groups spoke Kirundi.

The kingdom grew in two phases. Ntare I annexed neighbouring polities. In the early 19th century Ntare IV, who reigned from about 1795 to 1852, conquered several smaller kingdoms and, with Rwanda, divided the kingdom of Bugesera between them; the Wikipedia history says the kingdom doubled in size under him. By 1850 its borders largely overlapped with those of the modern state. In the 1880s his successor Mwezi IV defeated Zanzibari slave traders in a battle at Rumonge, and the kingdom article records that no slaves were ever taken or traded in Burundi as a result.

The symbol of the monarchy was the drum. The most important, the inkiranya, was said to have been made by the first mwami, and the royal drums were kept in sanctuaries guarded by particular Hutu families. The flag of the kingdom carried a karyenda drum at its centre.

What German and Belgian rule changed

Richard Burton and John Hanning Speke reached Burundi in 1858, looking for the source of the Nile along Lake Tanganyika, and Henry Morton Stanley and David Livingstone explored the lake in 1871. Mwezi IV resisted all of it. When three Catholic White Fathers came in 1881 they were killed, and he refused even European cotton clothing. Burundi was assigned to German East Africa in 1890, but Germany set up a military post only in 1896 and ruled largely through the mwami. In 1902 and 1903 a German resident, Friedrich Robert von Beringe, joined an anti-royal pretender called Kilima in a campaign against Mwezi IV and forced him to submit in the treaty of Ikiganda, which nonetheless recognised him as the rightful ruler. In 1912 the German administration moved its seat from Usumbura to Gitega, close to the royal heartland.

German rule left a light administrative mark and a heavy demographic one. Rinderpest and sleeping sickness spread in the same years, a great famine struck in 1905, and, according to the Wikipedia history, half the population of the western plains died between 1905 and 1914.

Belgian troops took Gitega on 17 June 1916, and the regency council ruling for the young Mwambutsa IV surrendered ten days later. The League of Nations then placed Burundi and Rwanda together under Belgium as Ruanda-Urundi; the kingdom article dates the mandate to 1922 and the history article to 1923. Belgium kept the kingdom's institutions and governed through them, but it imposed forced labour and more taxes, introduced coffee farming, and in the late 1920s reorganised the chieftaincies so that most chiefs and subchiefs were removed. The first motor road opened in 1932.

How the colonial state fixed Hutu and Tutsi

Britannica's history is explicit that Germany and especially Belgium turned fluid categories into fixed ones. Administrators assumed ethnicity could be read from physical features, treated Tutsi as superior on that basis, and favoured them in local administration. The Wikipedia civil war article records the working rule the Belgians used: a man with more than ten cows was normally described as Tutsi. Peasant uprisings in the 1920s and 1930s targeted both the Belgians and the Batare lineage, which was seen as closer to them than the Bezi.

Why the monarchy outlasted the colonial era

After 1945 Ruanda-Urundi became a United Nations trust territory, and the UN pressed Belgium from 1946 to prepare it for independence. Rwanda abolished its monarchy in a revolution between 1959 and 1961. Burundi's survived, and in the early 1960s it still had support among both Tutsi and Hutu.

On 20 January 1959 Mwambutsa IV asked Belgium for independence and for the dissolution of the Ruanda-Urundi union. The movement that followed was led by Prince Louis Rwagasore, a Bezi and the eldest son of the mwami, at the head of the Union for National Progress, UPRONA, a party that drew in both Hutu and Tutsi. Belgium backed the rival Christian Democratic Party, which did not seek immediate independence, and the old Bezi and Batare rivalry split along the same line. The Christian Democrats won the municipal elections of November 1960 while Rwagasore was under house arrest.

The legislative election of 8 September 1961 reversed that. Britannica gives UPRONA 58 of the 64 seats, 22 of them held by Hutu members. Rwagasore became prime minister and was assassinated on 13 October 1961, aged 29. Jean Kageorgis was convicted of the murder and accused the two senior Belgian officials in Burundi of involvement; the kingdom article links the killing to the Bezi and Batare rivalry. The anniversary is a public holiday under a 2021 presidential decree, which calls Rwagasore the national hero. Burundi became independent on 1 July 1962 as a kingdom in which the mwami held executive power and parliament legislated.

How the crown fell after independence

The monarchy lasted four years. On 15 January 1965 the Hutu prime minister Pierre Ngendandumwe was shot before he could form a government. The legislative elections of May 1965 gave Hutu candidates a majority in the National Assembly, and Mwambutsa IV appointed a ganwa confidant, Léopold Biha, as prime minister. Hutu officers attempted a coup in October 1965 and failed. Britannica records some 34 Hutu officers executed afterwards; the Wikipedia country article puts the toll of the army's reprisals at up to 5,000 people. Mwambutsa left the country and refused to return.

In July 1966 his son, Ntare V, deposed him. On 28 November 1966 Ntare was himself deposed by his prime minister, Captain Michel Micombero, a Tutsi-Bahima from Bururi, who abolished the monarchy and declared a republic. Gitega, seat of the kings, ceased to be a royal capital that year.

Why the killings of the republic are counted differently

The First Republic was a military government dominated by Hima officers from the south. On 29 April 1972 an insurgency broke out in the south: armed bands killed the civil and military authorities in Bururi, seized the armouries at Rumonge and Nyanza-Lac, killed Tutsi civilians and Hutu who refused to join them, and proclaimed a republic at Martyazo. Ntare V, who had returned from exile in March and been detained, was killed in Gitega on 29 April. The army then moved in and, through May and into August, killed Hutu civil servants, educated men and university and secondary school students. The historian René Lemarchand, quoted in the Wikipedia history, calls it a partial genocide.

No count is agreed, and the sources on file give these:

Britannica puts the 1972 dead at about 5% of the population and says more than 100,000 Hutu fled; the Wikipedia history gives about 300,000 refugees, most of them to Tanzania. In June 2025 Burundi asked the United Nations to recognise the massacres of Hutu in 1972 and 1973 as genocide.

Colonel Jean-Baptiste Bagaza, another Tutsi-Bahima from Bururi, took power in a bloodless coup in 1976. A constitution of 1981 kept a single party, and his government set out to bring the Roman Catholic Church under state control because it judged the church's policies to favour Hutu. Major Pierre Buyoya overthrew him in September 1987 and governed through a 30-member junta, the Military Committee for National Salvation. In August 1988 killings began again in the north, opening with attacks on Tutsi and followed by army reprisals. This time the government named the Hutu and Tutsi problem openly, formed a cabinet with a Hutu majority in October 1988, and set up a national commission whose work led to the constitution of March 1992, which required every party to include both Hutu and Tutsi.

How the first free election ended in war

Melchior Ndadaye of the Front for Democracy in Burundi, FRODEBU, won the presidential election of June 1993 against Buyoya and became the first Hutu head of state. He named a balanced government with Sylvie Kinigi, a Tutsi woman, as prime minister. On 21 October 1993 army officers staged a coup and killed him along with other FRODEBU leaders. Killings spread across the country in both directions: the Wikipedia civil war article estimates 50,000 to 100,000 dead within a year, about as many Hutu as Tutsi, while Britannica gives as many as 150,000 Tutsi killed in retribution and perhaps 50,000 others.

Ndadaye's successor, Cyprien Ntaryamira, died on 6 April 1994 in the crash of the plane carrying him and the Rwandan president near Kigali, the event that began the genocide in Rwanda. In Burundi a coalition government formed in September 1994 could not hold the country. A FRODEBU faction under Léonard Nyangoma took up arms as the CNDD-FDD, and Hutu rebel groups operated from bases in Zaire and Tanzania. In July 1996 the army reinstalled Buyoya, and neighbouring states imposed an embargo. Both sides recruited children; the government's militias took boys between 7 and 16.

What the Arusha agreement wrote into the state

Peace talks were mediated first by Julius Nyerere, the former president of Tanzania, and after his death in 1999 by Nelson Mandela. Formal talks with the rebels opened at Arusha on 15 June 1998, and the Arusha Peace and Reconciliation Agreement was signed in August 2000, though the two leading Hutu rebel groups refused to take part and fighting went on. The agreement provided for a transitional government with the presidency rotating every 18 months between a Tutsi and a Hutu, and for an army balanced between the two groups. Buyoya was sworn in under it in November 2001 and handed over to Domitien Ndayizeye, a Hutu, on 30 April 2003. The CNDD-FDD signed a power-sharing deal on 8 October 2003; the last rebel group, the FNL, signed a ceasefire in 2006.

A constitution approved in 2005 carried the agreement's arithmetic into law. The constitution adopted in 2018 keeps it: the National Assembly has at least 100 deputies in shares of 60% Hutu and 40% Tutsi, at least 30% of them women, plus three co-opted Twa deputies; ministers are at most 60% Hutu and 40% Tutsi; the Senate seats two delegates per province from different ethnic communities and three Twa. Article 289 gives the Senate five years to evaluate whether to end or continue the ethnic quotas. The same text keeps a door open to the past: under Article 4 the restoration of the monarchy has to be put to a referendum, and a party pursuing it peacefully may operate.

Why term limits became the next crisis

The first post-war president, Pierre Nkurunziza, was elected by parliament in August 2005 with 151 of 161 votes. In April 2015 his party confirmed him as its candidate for a third term. Opponents argued that the Arusha agreement and the constitution both allowed two terms; his supporters argued that the first had been an election by parliament and did not count. The Constitutional Court ruled for the third term on 5 May 2015, a general declared a coup on 13 May that failed within days, and the July 2015 presidential election went ahead without the opposition. Britannica cites estimates of about 1,200 people killed and more than 400,000 displaced between April 2015 and October 2017, the period the International Criminal Court opened an investigation into. Burundi left the court in October 2017, the first state to do so.

A referendum on 17 May 2018 approved a new constitution with a seven-year presidential term, a prime minister and a single vice-president. Britannica gives the yes vote as 73%, the Wikipedia history as 79.08%. On 24 December 2018 the government announced that the political capital would return to Gitega, the city of the kings, and parliament voted the change on 16 January 2019, with Bujumbura kept as the economic capital. Nkurunziza did not stand in May 2020 and died in June of that year; his successor was sworn in on 18 June 2020.
