Frequently asked questions

What is the official name of the Comoros?

The Union of the Comoros — Udzima wa Komori in Comorian, Union des Comores in French, al-Ittiḥād al-Qumurī in Arabic — since the constitution of 2001; the Federal Islamic Republic from 1978 and the State of the Comoros at independence in 1975. The name comes from the Arabic qamar, "moon" — Jazā'ir al-Qamar, the islands of the moon — the name Arab sailors gave the archipelago.

What is the capital of the Comoros?

Moroni, on the west coast of Grande Comore below the Karthala volcano — the capital since 1962 and of the independent state since 1975, with about 60,000 people, among the smallest capitals in Africa. Mutsamudu on Anjouan and Fomboni on Mohéli are the other island capitals; the Union claims a fourth island, Mayotte, which France governs from Mamoudzou.

How big are the Comoros, and how many people live there?

The three islands the Union governs — Grande Comore, Anjouan and Mohéli — cover 1,861 km² (719 sq mi), a little larger than Rhode Island's land; with Mayotte, which the Union claims and France holds, the archipelago is 2,235 km². The census of 2017 counted 758,316 people; the UN and the CIA World Factbook estimate about 870,000 for 2025, with more Comorians in France than on any one island. The islands are among the most densely peopled in Africa, above 450 per square kilometer.

What are the highest and lowest points of the Comoros?

Mount Karthala, 2,361 m (7,746 ft), the active shield volcano that makes up the southern two-thirds of Grande Comore — its summit caldera, about 3 by 4 km, is among the largest of any active volcano; it erupted in 2005, 2006 and 2007 — and the Indian Ocean. Anjouan rises to 1,595 m at Mount Ntingui and Mohéli to 790 m.

What currency do the Comoros use?

The Comorian franc (ISO code KMF, CF), issued by the Central Bank of the Comoros and fixed at 491.96775 to the euro since 1999 under a guarantee from France — the only currency besides the two CFA francs pegged that way. Clocks keep East Africa Time, UTC+3, all year.

Who governs the Comoros?

President Azali Assoumani, a former army colonel in office since 26 May 2016 — and before that from the coup of 1999 to 2006 — re-elected on 14 January 2024 with 57.02 percent of the vote by the Supreme Court's revised count, after electoral officials had first announced 63 percent, on a turnout the opposition disputed; days of protest followed. His second term under the constitution of 2018 runs to 2029, when he may not stand again. In August 2024 he gave broad powers over the government to his son, Nour El Fath Azali, widely seen as his intended successor; his party won 31 of the 33 seats of the Assembly in the election of January 2025. The Union has no prime minister; the president heads the government.
