In 1886, Mwali was placed under French protection by its Sultan Mardjani Abdou Cheikh. That same year, Sultan Said Ali of Bambao, one of the sultanates on Ngazidja, placed the island under French protection in exchange for French support of his claim to the entire island, which he retained until his abdication in 1910. In 1908 the islands were unified under a single administration ("Colonie de Mayotte et dépendances") and placed under the authority of the French colonial governor general of Madagascar. In 1909, Sultan Said Muhamed of Ndzuani abdicated in favour of French rule. In 1912 the colony and the protectorates were abolished and the islands became a province of the colony of Madagascar.
