Comoros
The Comoros also lays claim to the "Îles Éparses" or "Îles éparses de l'océan indien" (Scattered Islands in the Indian Ocean) – Glorioso Islands, comprising Grande Glorieuse, Île du Lys, Wreck Rock, South Rock, Verte Rocks (three islets) and three unnamed islets – one of France's overseas districts. 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 and France each still view the Banc du Geyser as part of the Glorioso Islands and, thus, part of its particular exclusive economic zone.
History of the Comoros
Apart from a visit by the French Parmentier brothers in 1529, for much of the 16th century the only Europeans to visit the islands were Portuguese; British and Dutch ships began arriving around the start of the 17th century and the island of Ndzwani soon became a major supply point on the route to the East. Ndzwani was generally ruled by a single sultan, who occasionally attempted to extend his authority to Mayotte and Mwali; Ngazidja was more fragmented, on occasion being divided into as many as 12 small kingdoms.
