Comoros

Settlement

According to mythology, a jinni dropped a jewel, which formed a great circular inferno. This became the Karthala volcano, which created the island of Ngazidja (Grande Comore). King Solomon is also said to have visited the island accompanied by his queen Bilqis.

The first attested human inhabitants of the Comoro Islands are now thought to have been Austronesian settlers travelling by boat from islands in Southeast Asia.^[28][29] These people arrived in the area no later than the eighth century AD, the date of the earliest known archaeological site, found on Mayotte, although settlement beginning in the first century has been postulated.^[30]

Subsequent settlers came from the east coast of Africa, the Arabian Peninsula and the Persian Gulf, the Malay Archipelago, and Madagascar. Bantu-speaking settlers were present on the islands from the beginnings of settlement.^{[chronology citation needed] [31]}

Development of the Comoros is divided into phases. The earliest reliably recorded phase is the Dembeni phase (eighth to tenth centuries), during which there were several small settlements on each island.^[32] From the eleventh to the fifteenth centuries, trade with the island of Madagascar and merchants from the Swahili coast and the Middle East flourished, more villages were founded and existing villages grew. Settlers from the Arabian peninsula, particularly Hadhramaut, arrived during this period.

Medieval Comoros and European contact

According to legend, in 632, upon hearing of Islam, islanders are said to have dispatched an emissary, Mtswa-Mwindza, to Mecca—but by the time he arrived there, the Islamic prophet Muhammad had died. Nonetheless, after a stay in Mecca, he returned to Ngazidja, where he built a mosque in his home town of Ntsaweni, and led the gradual conversion of the islanders to Islam.^[33]

In 933, the Comoros was referred to by Omani sailors as the Perfume Islands.^[34]

Among the earliest accounts of East Africa, the works of Al-Masudi describe early Islamic trade routes, and how the coast and islands were frequently visited by Muslims including Persian and Arab merchants and sailors in search of coral, ambergris, ivory, tortoiseshell, gold and slaves for the Arabic slave trade. They also brought Islam to the people of the Zanj including the Comoros. As the importance of the Comoros grew along the East African coast, both small and large mosques were constructed. The Comoros are part of the Swahili cultural and economic complex and the islands became a major hub of trade and an important location in a network of trading towns that included Kilwa, in present-day Tanzania, Sofala (an outlet for Zimbabwean gold), in Mozambique, and Mombasa in Kenya.^[32]

The Portuguese arrived in the Indian Ocean at the end of the 15th century, and the first Portuguese visit to the islands seems to have been that of Vasco da Gama's second fleet in 1503.^[35] For much of the 16th century, the islands provided provisions to the Portuguese fort at Mozambique, and although there was no formal attempt by the Portuguese crown to take possession, some Portuguese traders settled and married local women.

By the end of the 16th century, local rulers on the African mainland were beginning to push back and, with the support of the Omani Sultan Saif bin Sultan, they began to defeat the Dutch and the Portuguese. One of his successors, Said bin Sultan, increased Omani Arab influence in the region, moving his administration to nearby Zanzibar, which came under Omani rule. Nevertheless, the Comoros remained independent, and although the three smaller islands were usually politically unified, the largest island, Ngazidja, was divided into a number of autonomous kingdoms (ntsi).^[36]

The islands were well placed to meet the needs of Europeans, initially supplying the Portuguese in Mozambique, then ships, particularly the English, on the route to India, and, later, slaves to the plantation islands in the Mascarenes.^[37][36]

French colonisation

In the last decade of the 18th century, Malagasy warriors, mostly Betsimisaraka and Sakalava, started raiding the Comoros for slaves and the islands were devastated as crops were destroyed and the people were slaughtered, taken into captivity or fled to the African mainland: it is said that by the time the raids finally ended in the second decade of the 19th century only one man remained on Mwali.^[38] The islands were repopulated by slaves from the mainland, who were traded to the French in Mayotte and the Mascarenes. On the Comoros, it was estimated in 1865 that as much as 40% of the population consisted of slaves.^[39]

France first established colonial rule in the Comoros by taking possession of Mayotte in 1841 when the Sakalava usurper sultan Andriantsoly [fr] (also known as Tsy Levalo) signed the Treaty of April 1841,^[40] which ceded the island to the French authorities.^[41] After its annexation, France attempted to convert Mayotte into a sugar plantation colony.

Meanwhile, Ndzwani (or Johanna as it was known to the British) continued to serve as a way station for English merchants sailing to India and the Far East, as well as American whalers, although the British gradually abandoned it following their possession of Mauritius in 1814, and by the time the Suez Canal opened in 1869 there was no longer any significant supply trade at Ndzwani. Local commodities exported by the Comoros were, in addition to slaves, coconuts, timber, cattle, and tortoiseshell. British and American settlers, as well as the island's sultan, established a plantation-based economy that used about one-third of the land for export crops. In addition to sugar on Mayotte, ylang-ylang and other perfume plants, vanilla, cloves, coffee, cocoa beans, and sisal were introduced.^[42]

In 1886, Mwali was placed under French protection by its Sultan Mardjani Abdou Cheikh. That same year, Sultan Said Ali of Bambao, one of the sultanates on Ngazidja, placed the island under French protection in exchange for French support of his claim to the entire island, which he retained until his abdication in 1910. In 1908 the four islands were unified under a single administration (Colonie de Mayotte et dépendances) and placed under the authority of the French colonial Governor-General of Madagascar. In 1909, Sultan Said Muhamed of Ndzwani abdicated in favour of French rule, and in 1912, the protectorates were abolished and the islands administered as a single colony. Two years later, the colony was abolished, and the islands became a province of the colony of Madagascar.^[31]

An agreement was reached with France in 1973 for the Comoros to become independent in 1978, despite the deputies of Mayotte voting for increased integration with France. A referendum was held on all four of the islands. Three voted for independence by large margins, while Mayotte voted against. On 6 July 1975, however, the Comorian parliament passed a unilateral resolution declaring independence. Ahmed Abdallah proclaimed the independence of the Comorian State (État comorien; دولة القمر) and became its first president. France did not recognise the new state until 31 December, and retained control of Mayotte.

Independence to present

The next 30 years were a period of political turmoil. On 3 August 1975, less than one month after independence, president Ahmed Abdallah was removed from office in an armed coup and replaced with United National Front of the Comoros (FNUK) member Said Mohamed Jaffar. Months later, in January 1976, Jaffar was ousted in favour of his Minister of Defence Ali Soilihi.^[43]

The population of Mayotte voted against independence from France in three referendums during this period. The first, held on all the islands on 22 December 1974, won 63.8% support for maintaining ties with France on Mayotte; the second, held in February 1976, confirmed that vote with an overwhelming 99.4%, while the third, in April 1976, confirmed that the people of Mayotte wished to remain a French territory. The three remaining islands, ruled by President Soilihi, instituted a number of socialist and isolationist policies that soon strained relations with France. On 13 May 1978, Bob Denard, once again commissioned by the French intelligence service (SDECE), returned to overthrow President Soilihi and reinstate Abdallah with the support of the French, Rhodesian and South African governments. Ali Soilihi was captured and executed a few weeks later.^[43][44]

In contrast to Soilihi, Abdallah's presidency was marked by authoritarian rule and increased adherence to traditional Islam^[45] and the country was renamed the Federal Islamic Republic of the Comoros (République Fédérale Islamique des Comores; جمهورية القمر الإتحادية الإسلامية). Bob Denard served as Abdallah's first advisor; nicknamed the "Viceroy of the Comoros", he was considered the real strongman of the regime. Very close to South Africa, which financed his "presidential guard", he allowed Paris to circumvent the international embargo on the apartheid regime via Moroni. He also set up from the archipelago a permanent mercenary corps, called upon to intervene at the request of Paris or Pretoria in conflicts in Africa. Abdallah continued as president until 1989, when, fearing a probable coup, he signed a decree ordering the Presidential Guard, led by Bob Denard, to disarm the armed forces. Shortly after the signing of the decree, Abdallah was allegedly shot dead in his office by a disgruntled military officer, though later sources claim an antitank missile was launched into his bedroom and killed him.^[46]. Still, Denard was also injured; it is suspected that Abdallah's killer was a soldier under his command.^[47]

A few days later, Bob Denard was evacuated to South Africa by French paratroopers. Said Mohamed Djohar, Soilihi's older half-brother, then became president, and served until September 1995, when Bob Denard returned and attempted another coup. This time, France intervened with paratroopers and forced Denard to surrender.^[48][49] The French removed Djohar to Reunion, and the Paris-backed Mohamed Taki Abdoulkarim became president by election. He led the country from 1996, during a time of labour crises, government suppression, and secessionist conflicts, until his death in November 1998. He was succeeded by Interim President Tadjidine Ben Said Massounde.^[50]

The islands of Ndzwani and Mwali declared their independence from the Comoros in 1997, in an attempt to restore French rule. But France rejected their request, leading to bloody confrontations between federal troops and rebels.^[51] In April 1999, Colonel Azali Assoumani, Army Chief of Staff, seized power in a bloodless coup, overthrowing the Interim President Massounde, citing weak leadership in the face of the crisis. This was the Comoros' 18th coup, or attempted coup d'état since independence in 1975.^[52]

Assoumani failed to consolidate power and reestablish control over the islands, which was the subject of international criticism. The African Union, under the auspices of President Thabo Mbeki of South Africa, imposed sanctions on Ndzwani to help broker negotiations and effect reconciliation.^[53][54] Under the terms of the Fomboni Accords,^[55] signed in December 2001 by the leaders of all three islands, the official name of the country was changed to the Union of the Comoros; the new state was to be highly decentralised and the central union government would devolve most powers to the new island governments, each led by a president. The Union president, although elected by national elections, would be chosen in rotation from each of the islands every five years.

Assoumani stepped down in 2002 to run in the democratic election of the President of the Comoros, which he won. Under ongoing international pressure, as a military ruler who had originally come to power by force, and was not always democratic while in office, Assoumani led the Comoros through constitutional changes that enabled new elections.^[56] A Loi des compétences law was passed in early 2005 that defines the responsibilities of each governmental body, and is in the process of implementation. The elections in 2006 were won by Ahmed Abdallah Mohamed Sambi, a Sunni Muslim cleric nicknamed the "Ayatollah" for his time spent studying Islam in Iran. Assoumani honoured the election results, thus allowing the first peaceful and democratic exchange of power for the archipelago.^[57]

Colonel Mohammed Bacar, a French-trained former gendarme elected President of Ndzwani in 2001, refused to step down at the end of his five-year mandate. He staged a vote in June 2007 to confirm his leadership that was rejected as illegal by the Comoros federal government and the African Union. On 25 March 2008, hundreds of soldiers from the African Union and the Comoros seized rebel-held Ndzwani, generally welcomed by the population: there have been reports of hundreds, if not thousands, of people tortured during Bacar's tenure.^[58] Some rebels were killed and injured, but there are no official figures. At least 11 civilians were wounded. Some officials were imprisoned. Bacar fled in a speedboat to Mayotte to seek asylum. Anti-French protests followed in the Comoros (see 2008 invasion of Anjouan). Bacar was eventually granted asylum in Benin.

Since independence from France, the Comoros experienced more than 20 coups or attempted coups.^[22]

Following elections in late 2010, former Vice-president Ikililou Dhoinine was inaugurated as president on 26 May 2011. Dhoinine is the first President of the Comoros from the island of Mwali. Following the 2016 elections, Azali Assoumani, from Ngazidja, became president for a third term. In 2018, Assoumani held a referendum on constitutional reform that would permit a president to serve two terms. The amendments were passed, although the vote was widely contested and boycotted by the opposition, and in April 2019, to widespread opposition, Assoumani was re-elected president to serve the first of potentially two five-year terms.^[59] In January 2020, the legislative elections in Comoros were dominated by President Azali Assoumani's party, the Convention for the Renewal of the Comoros, CRC. It took an overwhelming majority in the parliament.^[60]

In 2021, Comoros signed and ratified the Treaty on the Prohibition of Nuclear Weapons, making it a nuclear-weapon-free state.^[61] and in 2023, Comoros was invited as a non-member guest to the G7 summit in Hiroshima.^[62] On 18 February 2023 the Comoros assumed the presidency of the African Union.^[63]

In January 2024, President Azali Assoumani was re-elected with 63% of the vote in the disputed presidential election.^[64] In January 2025, the ruling party of president Azali Assoumani won parliamentary election, taking 28 out of 33 parliamentary seats. The opposition parties rejected the results.^[65]

In 2026, the Historic Sultantes of the Comoro Islands were inscibred as a UNESCO World Heritage Site, making them the first Islamic sites to be listed in the Comoros.

The climate is generally tropical and mild, and the two major seasons are distinguishable by their raininess. The temperature reaches an average of 29–30 °C (84–86 °F) in March, the hottest month in the rainy season (called kashkazi/kaskazi [meaning north monsoon], which runs from November to April), and an average low of 19 °C (66 °F) in the cool, dry season (kusi (meaning south monsoon), which proceeds from May to October).^[68] The islands are rarely subject to cyclones.

Biodiversity

The Comoros constitute an ecoregion in their own right, Comoros forests.^[69][70] It had a 2018 Forest Landscape Integrity Index mean score of 7.69/10, ranking it 33rd globally out of 172 countries.^[71]

In December 1952 a specimen of the West Indian Ocean coelacanth fish was re-discovered off the Comoros coast. The 66-million-year-old species was thought to have been long extinct until its first recorded appearance in 1938 off the South African coast.^[72] Between 1938 and 1975, 84 specimens were caught and recorded.^[73]

There are six national parks in the Comoros – Karthala, Coelacanth, and Mitsamiouli Ndroudi on Grande Comore, Mount Ntringui and Shisiwani on Anjouan, and Mohéli National Park on Mohéli. Karthala and Mount Ntrigui national parks cover the highest peaks on the respective islands, and Coelacanth, Mitsamiouli Ndroudi, and Shisiwani are marine national parks that protect the island's coastal waters and fringing reefs. Mohéli National Park includes both terrestrial and marine areas.^[74]

Legal system

The Comorian legal system rests on Islamic law, an inherited French (Napoleonic Code) legal code, and customary law (mila na ntsi). Village elders, kadis or civilian courts settle most disputes. The judiciary is independent of the legislative and the executive. The Supreme Court acts as a Constitutional Council in resolving constitutional questions and supervising presidential elections. As High Court of Justice, the Supreme Court also arbitrates in cases where the government is accused of malpractice. The Supreme Court consists of two members selected by the president, two elected by the Federal Assembly, and one by the council of each island.^[76]

Political culture

Around 80 percent of the central government's annual budget is spent on the country's complex administrative system which provides for a semi-autonomous government and president for each of the three islands and a rotating presidency for the overarching Union government.^[77] A referendum took place on 16 May 2009 to decide whether to cut down the government's unwieldy political bureaucracy. 52.7% of those eligible voted, and 93.8% of votes were cast in approval of the referendum. Following the implementation of the changes, each island's president became a governor and the ministers became councillors.^[78]

Foreign relations

In November 1975, the Comoros became the 143rd member of the United Nations. The new nation was defined as comprising the entire archipelago, although the citizens of Mayotte chose to become French citizens and keep their island as a French territory.^[79]

The Comoros has repeatedly pressed its claim to Mayotte before the United Nations General Assembly, which adopted a series of resolutions under the caption "Question of the Comorian Island of Mayotte", opining that Mayotte belongs to the Comoros under the principle that the territorial integrity of colonial territories should be preserved upon independence. As a practical matter, however, these resolutions have little effect and there is no foreseeable likelihood that Mayotte will become de facto part of the Comoros without its people's consent. More recently, the Assembly has maintained this item on its agenda but deferred it from year to year without taking action. Other bodies, including the Organisation of African Unity, the Movement of Non-Aligned Countries and the Organisation of Islamic Cooperation, have similarly questioned French sovereignty over Mayotte.^[80][81] To close the debate and to avoid being integrated by force in the Union of the Comoros, the population of Mayotte overwhelmingly chose to become an overseas department and a region of France in a 2009 referendum. The new status was effective on 31 March 2011 and Mayotte has been recognised as an outermost region by the European Union on 1 January 2014. This decision legally integrates Mayotte in the French Republic.

The Comoros is a member of the United Nations, the African Union, the Arab League, the World Bank, the International Monetary Fund, the Indian Ocean Commission and the African Development Bank. On 10 April 2008, the Comoros became the 179th nation to accept the Kyoto Protocol to the United Nations Framework Convention on Climate Change.^[82] The Comoros signed the UN treaty on the Prohibition of Nuclear Weapons.^[83] Azali Assoumani, President of the Comoros and Chair of the African Union, attended the 2023 Russia–Africa Summit in Saint Petersburg.^[84]

In May 2013, the Union of the Comoros became known for filing a referral to the Office of the Prosecutor of the International Criminal Court (ICC) regarding the events of "the 31 May 2010 Israeli raid on the Humanitarian Aid Flotilla bound for the Gaza Strip". In November 2014 the ICC Prosecutor eventually decided^[85] that the events did constitute war crimes but did not meet the gravity standards of bringing the case before ICC.^[86]

The emigration rate of skilled workers was about 21.2% in 2000.^[87]

Military

The military resources of the Comoros consist of a small standing army and a 500-member police force, as well as a 600-member defence force.^[88][89] A defence treaty with France^[90] provides naval resources for protection of territorial waters, training of Comorian military personnel, and air surveillance. France maintains the presence of a few senior officers in the Comoros at government request, as well as a small maritime base and a Foreign Legion Detachment (DLEM) on Mayotte.

Once the new government was installed in May–June 2011, an expert mission from UNREC (Lomé) came to the Comoros and produced guidelines for the elaboration of a national security policy, which were discussed by different actors, notably the national defence authorities and civil society.^[91] By the end of the programme in end March 2012, a normative framework agreed upon by all entities involved in SSR will have been established.^{[needs update]} This will then have to be adopted by Parliament and implemented by the authorities.

Human rights

Both male and female same-sex sexual acts are illegal in Comoros.^[92] Such acts are punished with up to five years' imprisonment.^[93]

Ethnic groups

The islands of the Comoros are 97.1% ethnically Comorian, which is a mixture of Bantu, the Austronesian admixed Bantu Malagasy, and Arab people.^[1] Minorities include Makua and Indian (mostly Ismaili). There are recent immigrants of Chinese origin in Grande Comore (especially Moroni). Although most French left after independence in 1975, a small Creole community, descended from settlers from France, Madagascar and Réunion, lives in the Comoros.^[115]

Languages

The most common languages in the Comoros are the Comorian languages, spoken by over 95% of the population.^[116] These languages are collectively known as Shikomori and are related to Swahili. The four different variants of Comorian (Shingazidja, Shimwali, Shindzwani and Shimaore) are spoken on each of the four islands. Arabic and Latin scripts are both used, Arabic being the more widely used, and an official orthography has recently been developed for the Latin script.^[117]

Arabic and French are also official languages. Because no accepted standardized written form currently exists for Comorian, Arabic and French are used as the mediums of instruction from primary to tertiary education.^[116] Arabic is widely known as a second language, being the language of Quranic teaching. French is the administrative language and the language of most non-Quranic formal education. In addition, English is taught in later grades.^[118]

A 2025 Afrobarometer survey found that 89.9% of Comorians primarily speak Shikomori at home while 9.9% have French as their main home language.^[2]

Religion

Sunni Islam is the dominant religion, followed by as much as 99% of the population.^[119] Comoros is the only Muslim-majority country in Southern Africa and one of the three southernmost Muslim-majority territories, along with Mayotte and the Australian territory of Cocos Islands. A minority of the population of the Comoros are Christian, both Catholic and Protestant denominations are represented, and most Malagasy residents are also Christian. Immigrants from metropolitan France are mostly Catholic.^[120]

Health

The Comoros has 15 physicians per 100,000 people. The fertility rate was 4.7 births per adult woman in 2004. Life expectancy at birth is 67 years for females and 62 years for males,^[121] with the average life expectancy being 63.42 years in 2021. The Comorian National Institute of Statistics has found that the total fertility rate (TFR) in the country has decreased over time, from a peak of 7.14 in 1973 to 3.98 in 2021.^[7] Although the infant mortality rate in the Comoros declined sharply from 152 to 47 deaths per 1,000 live births between 1970 and 2020,^[7] it remains high compared to rates in developed countries.^[122]

In the 2024 Global Hunger Index (GHI), Comoros ranks 81st out of 127 countries with sufficient data, with a score of 18.8, which indicates a moderate level of hunger.^[123]

Marriage

There are two types of marriages in Comoros, the little marriage (known as Mna daho on Ngazidja) and the customary marriage (known as ada on Ngazidja, harusi on the other islands). The little marriage is a simple legal marriage. It is small, intimate, and inexpensive, and the bride's dowry is nominal. A man may undertake a number of Mna daho marriages in his lifetime, often at the same time, a woman fewer; but both men and women will usually only undertake one ada, or grand marriage, and this must generally be within the village. The hallmarks of the grand marriage are dazzling gold jewelry, two weeks of celebration and an enormous bridal dowry. Although the expenses are shared between both families as well as with a wider social circle, an ada wedding on Ngazidja can cost up to €50,000.^[131] Many couples take a lifetime to save for their ada, and it is not uncommon for a marriage to be attended by a couple's adult children.^[132]

The ada marriage marks a man's transition in the Ngazidja age system from youth to elder. His status in the social hierarchy greatly increases, and he will henceforth be entitled to speak in public and participate in the political process, both in his village and more widely across the island. He will be entitled to display his status by wearing a mharuma, a type of shawl, across his shoulders, and he can enter the mosque by the door reserved for elders, and sit at the front. A woman's status also changes, although less formally, as she becomes a "mother" and moves into her own house. The system is less formalised on the other islands, but the marriage is nevertheless a significant and costly event across the archipelago. The ada is often criticized because of its great expense, but at the same time it is a source of social cohesion and the main reason why migrants in France and elsewhere continue to send money home. Increasingly, marriages are also being taxed for the purposes of village development.^[133]

Kinship and social structure

Comorian society has a bilateral descent system. Lineage membership and inheritance of immovable goods (land, housing) is matrilineal, passed in the maternal line, similar to many Bantu peoples who are also matrilineal, while other goods and patronymics are passed in the male line. However, there are differences between the islands, the matrilineal element being stronger on Ngazidja.^[133]

Music

Twarab music, imported from Zanzibar in the early 20th century, remains the most influential genre on the islands and is popular at ada marriages.^[134]

Media

There are two daily national newspapers published in the Comoros, the government-owned Al-Watwan,^[135] and the privately owned La Gazette des Comores, both published in Moroni. There are a number of smaller newsletters published on an irregular basis as well as a variety of news websites. The government-owned ORTC (Office de Radio et Télévision des Comores) provides national radio and television service. There is a TV station run by the Anjouan regional government, and regional governments on the islands of Grande Comore and Anjouan each operate a radio station. There are also a few independent and small community radio stations that operate on the islands of Grande Comore and Mohéli, and these two islands have access to Mayotte Radio and French TV.^[136]
