evidence: Mayotte is an overseas département (department) of France. From 1976 into the 21st century, Mayotte had a special status with France as a collectivité territoriale (territorial collectivity), conceived as being midway between an overseas territory and an overseas département. Its status was changed to collectivité départementale (departmental collectivity) in 2001 and then to overseas département in 2011. Mayotte’s status as an administrative unit of France has been disputed by Comoros, which has claimed Mayotte since Comoros’s declaration of independence from France in 1975. [...] In the 15th century Arabs invaded the island and converted its inhabitants, who were probably descendants of earlier peoples speaking Bantu and Malay and Indonesian languages, to Islam; in the 16th century the Portuguese and French visited Mayotte. At the end of the 18th century the Sakalava, a Malagasy tribe from Madagascar, invaded and populated the island, bringing a Malagasy dialect. The French gained colonial control over Mayotte in 1843, and, together with the other islands of the Comoros archipelago and Madagascar, Mayotte became part of a single French overseas territory in the early 20th century.
