evidence: - Mayotte (also known as or Maore) became independent from The Comoros Islands in 1978, (Comoros continues to lay claim to Mayotte, supported by many UN states), but elected to remain a French overseas territory and subsequently a département of France. - Mayotte is the newest of the five French overseas départements, having changed from an overseas collectivity with OCT status on 31 March 2011. It became an outermost region, and thus part of the EU, on 1 January 2014 - The currency is the euro and the official language (of course) is French. Fluent French is almost a necessity for travellers. Most of the locals do not have French as their first language, though nearly all of them speak French. Those locals who do speak English are not very interested in using this knowledge. [...] - Mayotte is a département of France, so its official flag is the tricolore of France. This is its unofficial flag, the coat of arms of the island.
