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. [...] The French administered Mayotte separately from the remainder of the Comoros beginning in 1975, when the three northernmost and predominantly Muslim islands of the Comoros declared independence, and the Muslim and Christian inhabitants of Mayotte chose to remain with France. In 1976 the French government introduced a special status of collectivité territoriale for the island. In 1979 the United Nations passed a resolution affirming the sovereignty of Comoros over Mayotte. The African Union also supported Comoros’s claim to the island.
