Mayotte became an overseas department of France in March 2011 in consequence of a 29 March 2009 referendum. The outcome was a 95.5 percent vote in favour of changing the island's status from a French "overseas community" to become France's 101st département. Its non-official traditional Islamic law, applied in some aspects of the day-to-day life, will be gradually abolished and replaced by the uniform French civil code. Additionally, French social welfare and taxes apply in Mayotte, though some of each will be brought in gradually. Comoros continues to claim the island, while criticising the French military base there.
