People & Culture

The Comoros gathers four volcanic islands into the channel between Madagascar and the East African coast: Grande Comore, also called Ngazidja, Anjouan or Nzwani, Moheli or Mwali, and Mayotte or Maore, the last of them governed from Paris rather than from Moroni, a split that runs through everything else in this history. Grande Comore carries the youngest and largest of the group's volcanoes, Karthala, an active shield volcano rising 2,361 metres to a summit caldera roughly three by four kilometres wide, among the largest calderas on any active volcano on the planet. Karthala has erupted more than twenty times since the nineteenth century, most recently in January 2007, and has shown renewed seismic unrest since 2021 without a confirmed eruption. People reached these islands from more than one direction. Austronesian sailors out of island Southeast Asia arrived between the eighth and thirteenth centuries, carrying Asian crops such as rice and cotton, while Bantu-speaking communities from the neighbouring East African coast settled alongside and eventually intermarried with them, and genetic studies estimate roughly a fifth of Comorian ancestry as Austronesian with the rest predominantly African. The clearest window onto this early period is the archaeological site of Dembeni, occupied across the ninth to twelfth centuries in two distinct phases, where excavators have found early Chinese and Persian ceramics, Mecca-oriented burials pointing to Islam's arrival by the eleventh or twelfth century, a necropolis holding individuals identified as both Austronesian and Bantu, and a lime kiln built with Austronesian firing technology. The pottery alone marks the islands as already plugged into Indian Ocean trade routes centuries before any sultan ruled here. From the fifteenth century, oral tradition credits the islands' ruling houses to Shirazi migrants from the Persian Gulf, reinforced from the sixteenth century by Hadhrami Arab lineages, and Islam consolidated alongside them as the framework for law and legitimacy. Most historians now treat that Shirazi origin story less as a literal migration record than as a legitimising narrative, a claim to prestige that Swahili and Comorian elites across the wider coast adopted in strikingly similar form, and while genetic sampling has found some markers consistent with medieval Persian contact, modern Comorian ancestry remains overwhelmingly African by both maternal and paternal lines, so the genetics support contact rather than settling the question of a founding dynasty. Grande Comore's own version of the story bends further still, since local tradition holds that it was Shirazi princesses rather than princes who married into ruling families, an adaptation that let a patrilineal Swahili legend fit a matrilineal Comorian society. By the seventeenth century Grande Comore alone had fragmented into eleven competing sultanates, Itsandra and Bambao the strongest among them, a pattern of small rival courts that would leave the islands poorly placed to withstand what came next. What came next was integration into the wider Swahili trading world, the string of coastal city-states and island ports running from southern Somalia down through the Comoros to Madagascar and Mozambique. Anjouan in particular functioned as a trans-shipment hub rather than as a producer in its own right, since Comorian sewn ships crossed to Madagascar for rice, millet, ambergris and ivory, added cowries fished from local reefs, and carried the cargo on to Pate, Lamu, Hadramaut and India, returning with silk cloth and iron weapons. Imported ceramics and glass beads found at Comorian sites suggest the islands also sat on a route toward Chibuene on the Mozambican coast, a further link in a trade network that had already made the Comoros cosmopolitan long before any European ship appeared offshore. That prosperity broke down in the late eighteenth and early nineteenth centuries under a sustained assault from Madagascar. From 1785, Sakalava war fleets from Madagascar's west coast began seasonal slaving raids on the Comoros, sacking Mutsamudu on Anjouan in 1796, 1798, 1803 and 1808, and hitting Mayotte in 1797 and Grande Comore in 1798. Thousands of islanders were carried off to work the sugar plantations of French Madagascar, Mauritius and Reunion, whole villages were depopulated, and the archipelago's sultanates emerged from the raids too weakened to resist the European powers now circling the western Indian Ocean. France took its first foothold in 1841, when Andriantsouly, the Malagasy ruler installed on Mayotte, ceded the island in exchange for French protection against both the Sakalava raiders and Anjouan's territorial ambitions, plus a lifetime pension, with formal cession following in 1843. Protectorate treaties extended French control over the remaining islands across the following decades, with Grande Comore's last sultan, Said Ali, signing his own treaty in 1886, and full colonial administration of all four islands was in place by 1912. French settlers, companies and Arab merchants then built a plantation economy across roughly a third of the arable land, sugar first on Mayotte and soon after ylang-ylang, vanilla, coffee, cocoa and sisal across the group, an export structure the islands never fully left behind. Independence arrived in two contradictory pieces. A referendum across the whole archipelago on 22 December 1974 returned 96 percent in favour of leaving France, but Mayotte alone had voted the other way, and the two governments read the outcome differently, since Paris treated the independence accord of 1973 as requiring an island-by-island result while Moroni and the United Nations read it as one nationwide count. The Comorian parliament broke the impasse unilaterally, declaring independence for all four islands, Mayotte included, on 6 July 1975, with Ahmed Abdallah as president. France responded by legislating, on 31 December 1975, to grant independence to the other three islands while carving Mayotte out, and put the question to Mayotte alone on 8 February 1976, when 99.4 percent voted to stay French, a vote France defended by casting its only Security Council veto in the organisation's history to stop the UN blocking it. Mayotte has remained French ever since and has been a full overseas department since 2011, even as the UN General Assembly passed resolution after resolution through the late 1970s, the 1980s and into the 1990s calling on France to respect the unity and territorial integrity of the archipelago as all four islands together and to negotiate Mayotte's return to Comorian sovereignty. France recognises none of it. The dispute remains open today, and it sits at the centre of how Comorians understand their own borders. Abdallah's government did not last the summer. On 3 August 1975, less than a month after independence, the French mercenary Bob Denard led a coup that deposed him, installing Ali Soilih in his place, reportedly on instruction from Jacques Foccart, the longtime Africa adviser at the Elysee. Soilih's turn toward radical socialism cost him Denard's backing in turn, since Denard returned with forty-three men on 13 May 1978, Soilih died two weeks later in disputed circumstances, and Abdallah, recalled from exile, took back the presidency. Denard then stayed on for over a decade as commander of the presidential guard, the country's real power behind an elected front, his position underwritten in part by apartheid-era South Africa. That arrangement ended in bloodshed, since after a referendum in November 1989 extended Abdallah's rule, Abdallah was shot dead in his residence on the night of 26 to 27 November, reportedly on Denard's order, and Denard's guard staged a further coup two days later before international pressure forced him out of the country on 15 December 1989. He tried a fourth time on 28 September 1995, landing at Moroni harbour with thirty-three men in inflatable boats, but this time Paris sent its own troops and the mercenaries surrendered within days. Four coups, one Frenchman, twenty years: few countries anywhere have had their politics shaped so continuously by a single outside operator. Instability outlived Denard. In August 1997 Anjouan and Moheli declared independence from the union, resentful of Grande Comore's grip on national politics and revenue, and a government force sent to retake Anjouan that September was routed. Colonel Azali Assoumani, who seized national power in a coup in 1999, chose negotiation over reconquest, and the Fomboni accords of 2000 and 2001 rebuilt the state as a union in which the presidency rotates among the three islands and each retains its own local president and assembly, a settlement approved by referendum in December 2001 and tested at the polls for the first time in 2002. Against that turbulent record, the islands built one genuinely singular export industry. The Comoros, alongside Madagascar and Mayotte, ranks among the world's leading sources of ylang-ylang, the yellow flower distilled into the essential oil behind classic perfumes including Chanel No. 5, with around ten thousand growers, most of them on Anjouan, supplying a trade worth several million dollars annually to France, Switzerland, the United States and Britain, while the country also stands as the world's second largest vanilla producer. Agriculture built on these two crops, alongside cloves, still accounts for roughly a third of GDP, a smallholder inheritance of the plantation economy the French laid down two centuries ago. The islands earned a stranger kind of fame in 1952, when a coelacanth was caught in Comorian waters, only the second confirmed specimen anywhere since a South African museum curator first identified the species from a trawler's catch in 1938. The find, after a fourteen-year search, established the Comoros as the true stronghold of a lobe-finned fish once thought to have gone extinct alongside the dinosaurs, and coelacanths are still occasionally landed by local fishermen working deep water off Grande Comore and Anjouan today. A visitor standing at Karthala's crater rim today looks down into a caldera four kilometres across, quiet since 2007 but still watched closely by the island's seismologists. In Moroni's medina, the Old Friday Mosque's coral-stone walls and carved wooden doors date to 1427, with its minaret a later addition from 1921, which makes it the oldest building in a quarter of narrow lanes that has changed shape only slowly since. Off Moheli's southern coast, the marine park created in 2001 out of a village-led turtle-protection campaign still draws green sea turtles to nest on the beaches at Itsamia. On Anjouan, Mount Ntringui rises over a national park holding a crater lake and the island's largest surviving forest, while Moheli's own volcanic crater lake at Dziani Boundouni sits inside steep green-walled cliffs on the island's southern lowlands. Back on Grande Comore, the saline crater lake known as Lac Sale lies a short walk from Chomoni's black volcanic rock and white sand, with Bouni beach, among the most photographed stretches of coastline in the country, close by. Move through this history carefully. The Old Friday Mosque is a working place of prayer rather than a museum exhibit, so dress modestly and ask before photographing anyone in the medina's residential lanes. At Moheli's nesting beaches, keep to the marine park's guides and its rules on distance, light and timing around the turtles, since the same shoreline was fought over long before conservation gave it a name. And on the question of Mayotte, let Comorians set the terms of that conversation rather than arriving with a settled opinion, since for a country whose parliament and whose flag still count four islands it remains an open matter rather than a closed one.
