The Comoros /ˈkɒməroʊz/ (Arabic: جزر القمر‎, Ǧuzur al-Qumur/Qamar), officially the Union of the Comoros (Comorian: Udzima wa Komori, French: Union des Comores, Arabic: الاتحاد القمري‎ al-Ittiḥād al-Qumurī/Qamarī) is an archipelago island nation in the Indian Ocean, located off the eastern coast of Africa, on the northern end of the Mozambique Channel, between northeastern Mozambique and northwestern Madagascar. Other countries near to the Comoros are Tanzania to the northwest and the Seychelles to the northeast. The capital is Moroni on Grande Comore.

At 1,862 km (719 sq mi) (excluding Mayotte), the Comoros is the third-smallest African nation by area. With a population estimated at 798,000 (excluding Mayotte). Its name derives from the Arabic word قمر qamar ("moon"). The archipelago is notable for its diverse culture and history, as a nation formed at the crossroads of many civilizations. It is the southernmost member state of the Arab League. Though in the contested island of Mayotte the sole official language is French, the "Union of the Comoros" has three official languages: Comorian, Arabic, and French.

The country officially consists of the four islands in the volcanic Comoros archipelago: northwesternmost Grande Comore or Ngazidja, Mohéli or Mwali, Anjouan or Nzwani, and southeasternmost Mayotte or Maore, as well as many smaller islands. However, the government of the Comoros (or its predecessors, since independence) has never administered the island of Mayotte, which France administers as an overseas department. Mayotte was the only island in the archipelago that voted against independence from France in 1974; the latter has vetoed United Nations Security Council resolutions that would affirm Comorian sovereignty over the island. In addition, a 29 March 2009 referendum on Mayotte's becoming an overseas department of France in 2011 was passed overwhelmingly by the people of Mayotte.

The Comoros is the only state to be a member of all of the following: African Union, Francophonie, Organisation of Islamic Cooperation, Arab League, and Indian Ocean Commission. The country has had a history marked by numerous coups d'état since independence in 1975. As of 2008 about half the population lives below the international poverty line of US$1.25 a day.

Precolonial inhabitation

The first human inhabitants of the Comoros Islands are thought to have been African and Austronesian settlers who traveled to the islands by boat. These people arrived no later than the sixth century AD, the date of the earliest known archaeological site, found on Nzwani, although settlement beginning as early as the first century has been postulated. The islands of Comoros became populated by a succession of diverse groups from the coast of Africa, the Persian Gulf, the Malay Archipelago, and Madagascar. Swahili settlers first reached the islands as a part of the greater Bantu expansion that took place in Africa throughout the first millennium.

According to a famous pre-Islamic mythology: A jinni (possibly Spirit) dropped a jewel, which formed a great circular inferno. This became the Kartala volcano which, created the island of Comoros. The early inhabitants of the islands worshiped nature and most probably the moon which they believed controlled the tides, these beliefs unified the islands.

Development of the Comoros is divided into phases, beginning with Swahili influence and settlement in the Dembeni phase (ninth to tenth centuries), during which each island maintained a single, central village. From the eleventh to the fifteenth centuries, trade with the island of Madagascar and merchants from the Middle East flourished, smaller villages emerged, and existing towns expanded. The citizens and historians of the Comoros state that early Arab settlements date to even before their known arrival to the archipelago, and Swahili historians frequently trace genealogies back to Arab ancestors who had traveled from Yemen mainly Hadhramawt and Oman.

In the year 933 Al-Masudi mentions Omani sailors, who call the Comoros islands "The Perfume Islands" and sing of waves that break rhythmically along broad, pearl-sand beaches, the light breezes scented with Vanilla and ylang-ylang, a component in many perfumes.

In 1154, Arab geographer al-Idrisi depicted the Comoros on a map and mentioned how its sailors sold metal tools for gold and ivory in East Africa; he considered the island more stable and individually prosperous than the busy coastal ports of Mombasa, Zanzibar, Kilwa and Kitao. In the 15th century, the Arab seafarer Ahmad ibn Majid drew the individual routes among these islands.

Medieval Comoros

According to legend, in 632, upon hearing of Islam, islanders are said to have dispatched an emissary, the navigator Qumralu, to Mecca—but by the time he arrived there, the Prophet Muhammad had died. Nonetheless, after a stay in Mecca, he returned to Qanbalu and led the gradual conversion of his islanders to Islam.

Some of the earliest accounts on the island of Comoros were derived from the works of Al-Masudi, that mentions the importance of the Comoro Islands, like other coastal areas in the region, along early Islamic trade routes and how the islands were frequently visited by Muslims including Persian and Arab merchants and sailors from Basra in search of coral, vanilla, ylang-ylang, ivory, beads, spices, gold, they also brought Islam to the people of the Zanj including Comoros. As the importance of Comoros grew along the East African coast small mosques and large mosques were constructed. Despite its distance from the coast, Comoros is situated along the Swahili Coast in East Africa. It was a major hub of trade and an important location in the sea route between Kilwa (an outlet for Zimbabwean gold) in Mozambique and Mombasa in Kenya.

After the arrival of the Portuguese and the collapse of East African sultanates, the powerful Omani Sultan Saif bin Sultan began to defeat the Dutch and the Portuguese. His successor Said bin Sultan increased Omani Arab influence in region especially when nearby Zanzibar came under Omani rule, and Comorian culture, especially architecture and religion also inhibited features that were unique to the plurality of the region. Sultans on the Comoros a large community of rival rulers controlled much of the islands in the sixteenth and seventeenth centuries.

By the time Europeans showed interest in the Comoros, the traditional Muslim, Swahili and Arab heritage islands began to adopt to the changes introduced by European colonization. More recent western scholarship by Thomas Spear and Randall Pouwells emphasizes black African historical predominance over the diffusionist perspective.

European contact and French colonization

Portuguese explorers first visited the archipelago in 1505.

By the year 1506 the Portuguese landed on the islands and began to challenge the Bajas (Bantu Muslim chiefs) and Fanis (lesser chiefs). In the years that followed the islands were sacked by the forces of Afonso de Albuquerque in the year 1514 by the Portuguese. The ruler of the Comoran Muslims barely survived after hiding in an extinct volcanic crater and despite the inadequacy of their cover, the Portuguese miraculously never found them. In the year 1648 the islands were raided by the Malagasy pirates, they sacked Iconi, a coastal trading hub near Ngazidja after defeating the weak Sultan.

In 1793, Malagasy warriors from Madagascar first started raiding the islands for slaves, and later settled and seized control in many locations. On Comoros, it was estimated in 1865 that as much as 40% of the population consisted of slaves. France first established colonial rule in the Comoros in 1841. The first French colonists landed in Mayotte, and Andrian Tsouli, the Malagasy King of Mayotte, signed the Treaty of April 1841, which ceded the island to the French authorities.

In 1886, Mohéli was placed under French protection by its Queen Salima Machimba. That same year, after consolidating his authority over all of Grande Comore, Sultan Said Ali agreed to French protection of his island, though he retained sovereignty until 1909. Also in 1909, Sultan Said Muhamed of Anjouan abdicated in favor of French rule. The Comoros (or Les Comores) was officially made a French colony in 1912, and the islands were placed under the administration of the French colonial governor general of Madagascar in 1914.

The Comoros served as a way station for merchants sailing to the Far East and India until the opening of the Suez Canal significantly reduced traffic passing through the Mozambique Channel. The native commodities exported by the Comoros were coconuts, cattle and tortoiseshell. French settlers, French-owned companies, and wealthy Arab merchants established a plantation-based economy that now uses about one-third of the land for export crops. After its annexation, France converted Mayotte into a sugar plantation colony. The other islands were soon transformed as well, and the major crops of ylang-ylang, vanilla, coffee, cocoa bean, and sisal were introduced.

Agreement was reached with France in 1973 for Comoros to become independent in 1978. The deputies of Mayotte abstained. Referendums were held on all four of the islands. Three voted for independence by large margins, while Mayotte voted against, and remains under French administration. On July 6, 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.

Independence

The next 30 years were a period of political turmoil. On 3 August 1975, mercenary Bob Denard, with clandestine support from Jacques Foccart and the French government, removed president Ahmed Abdallah from office in an armed coup and replaced him with United National Front of the Comoros (UNF) member Prince Said Mohammed Jaffar. Months later, in January 1976, Jaffar was ousted in favor of his Minister of Defense Ali Soilih.

At this time, the population of Mayotte voted against independence from France in two referendums. The first, held in December 1974, won 63.8% support for maintaining ties with France, while the second, held in February 1976, confirmed that vote with an overwhelming 99.4%. The three remaining islands, ruled by President Soilih, instituted a number of socialist and isolationist policies that soon strained relations with France. On 13 May 1978, Bob Denard returned to overthrow President Soilih and reinstate Abdallah with the support of the French and South African governments. During Soilih's brief rule, he faced seven additional coup attempts until he was finally forced from office and killed.

In contrast to Soilih, Abdallah's presidency was marked by authoritarian rule and increased adherence to traditional Islam and the country was renamed the Federal Islamic Republic of Comoros (République Fédérale Islamique des Comores; جمهورية القمر الإتحادية الإسلامية ). Abdallah continued as president until 1989 when, fearing a probable coup d'état, 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. Although Denard was also injured, it is suspected that Abdallah's killer was a soldier under his command.

A few days later, Bob Denard was evacuated to South Africa by French paratroopers. Said Mohamed Djohar, Soilih'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. The French removed Djohar to Reunion, and the Paris-backed Mohamed Taki Abdulkarim became president by election. He led the country from 1996, during a time of labor crises, government suppression, and secessionist conflicts, until his death November 1998. He was succeeded by Interim President Tadjidine Ben Said Massounde.

The islands of Anjouan and Mohéli 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. 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 d'état since independence in 1975. Azali, however, 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 Anjouan to help broker negotiations and effect reconciliation. The official name of the country was changed to the Union of the Comoros and a new system of political autonomy was instituted for each island, plus a union government for the three islands was added.

Azali 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, Azali led the Comoros through constitutional changes that enabled new elections. 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. Azali honored the election results, thus allowing the first peaceful and democratic exchange of power for the archipelago.

Colonel Mohammed Bacar, a French-trained former gendarme, seized power as President in Anjouan in 2001. 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 March 25, 2008 hundreds of soldiers from the African Union and Comoros seized rebel-held Anjouan, generally welcomed by the population: there have been reports of hundreds, if not thousands, of people tortured during Bacar’s tenure. 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 the French Indian Ocean territory of Mayotte to seek asylum. Anti-French protests followed in Comoros (see 2008 invasion of Anjouan).

Since independence from France, the Comoros experienced more than 20 coups or attempted coups.

The Comoros is formed by Ngazidja (Grande Comore), Mwali (Mohéli), Nzwani (Anjouan), and Maore (Mayotte), the major islands in the Comoros Archipelago, as well as many minor islets. The islands are officially known by their Comorian language names, though international sources still use their French names (given in parentheses above). The capital and largest city, Moroni, is located on Ngazidja. The archipelago is situated in the Indian Ocean, in the Mozambique Channel, between the African coast (nearest to Mozambique and Tanzania) and Madagascar, with no land borders.

At 2,235 km (863 sq mi), it is one of the smallest countries in the world. The Comoros also has claim to 320 km (120 sq mi) of territorial seas. The interiors of the islands vary from steep mountains to low hills. The climate is generally tropical and mild, and the two major seasons are distinguishable by their relative raininess. The temperature reaches an average of 29–30 °C (84–86 °F) in March, the hottest month in the rainy season (called kashkazi, December to April), and an average low of 19 °C (66 °F) in the cool, dry season (kusi, May to November). The islands are rarely subject to cyclones.

Ngazidja is the largest of the Comoros Archipelago, approximately equal in area to the other islands combined. It is also the most recent island, and therefore has rocky soil. The island's two volcanoes, Karthala (active) and La Grille (dormant), and the lack of good harbors are distinctive characteristics of its terrain. Mwali, with its capital at Fomboni, is the smallest of the four major islands. Nzwani, whose capital is Mutsamudu, has a distinctive triangular shape caused by three mountain chains, Sima, Nioumakele, and Jimilime, emanating from a central peak, Ntringi (1,575 m or 5,167 ft).

The oldest of the islands, Maore has the richest soil as well as good harbors and local fish populations, due to its ring of coral reefs. Dzaoudzi, the previous capital of all the colonial Comoros, is located on Pamanzi, (French: Petite-Terre), the largest islet of Maore. Maore's current capital is at Mamoudzou. The term Mayotte (or Maore) may also refer to the group of islands, of which the largest is known as Maore (French: Grande-Terre), and it includes Maore's surrounding islands, most notably Pamanzi (Petite-Terre).

The islands of the Comoros Archipelago were formed by volcanic activity. Mount Karthala, an active shield volcano located on Ngazidja, is the country's highest point, at 2,361 m or 7,748 ft (2,362 m) It contains the Comoros' largest patch of its disappearing rainforest. Karthala is currently one of the most active volcanoes in the world, with a minor eruption in May 2006, and prior eruptions as recently as April 2005 and 1991. In the 2005 eruption, which lasted from April 17 to 19, 40,000 citizens were evacuated, and the crater lake in the volcano's 3 by 4 km (1.9 by 2.5 mi) caldera was destroyed.

The Comoros also lays claim to the Glorioso Islands, comprising Grande Glorieuse, Île du Lys, Wreck Rock, South Rock, Verte Rocks (three islets), and three unnamed islets, one of France's Îles Éparses or Îles éparses de l'océan indien (Scattered islands in the Indian Ocean) possessions. The Glorioso Islands were administered by the colonial Comoros before 1975, and are therefore sometimes considered part of the Comoros Archipelago. Banc du Geyser, a former island in the Comoros Archipelago, now submerged, is geographically located in the Îles Éparses, but was annexed by Madagascar in 1976 as an unclaimed territory. The Comoros now claims it as part of its exclusive economic zone.

The Comoros constitute an ecoregion in their own right, Comoros forests.
