The Comoros (/ˈkɒməroʊz/ (About this soundlisten); Arabic: جزر القمر, Juzur al-Qumur / Qamar), officially the Union of the Comoros (Comorian: Umoja wa Komori, French: Union des Comores, Arabic: الاتحاد القمري al-Ittiḥād al-Qumurī / Qamarī), is an island country in the Indian Ocean located at the northern end of the Mozambique Channel off the eastern coast of Africa between northeastern Mozambique, the French region of Mayotte, and northwestern Madagascar. The capital and largest city in Comoros is Moroni. The religion of the majority of the population is Sunni Islam.
At 1,660 km2 (640 sq mi), excluding the contested island of Mayotte, the Comoros is the fourth-smallest African nation by area. The population, excluding Mayotte, is estimated at 795,601. As a nation formed at a crossroads of different civilisations, the archipelago is noted for its diverse culture and history. The archipelago was first inhabited by Bantu speakers who came from East Africa, supplemented by Arab and Austronesian immigration.
The sovereign state is an archipelago consisting of three major islands and numerous smaller islands, all in the volcanic Comoro Islands. The major islands are commonly known by their French names: northwestern-most Grande Comore (Ngazidja), Mohéli (Mwali), and Anjouan (Nzwani). In addition, the country has a claim on a fourth major island, southeastern-most Mayotte (Maore), though Mayotte voted against independence from France in 1974, has never been administered by an independent Comoros government, and continues to be administered by France (currently as an overseas department). France has vetoed United Nations Security Council resolutions that would affirm Comorian sovereignty over the island. In addition, Mayotte became an overseas department and a region of France in 2011 following a referendum passed overwhelmingly.
