 France officially ceded Mauritius including all its dependencies to the United Kingdom (UK) through the Treaty of Paris, signed on 30 May 1814 and in which Réunion was returned to France.The British colony of Mauritius consisted of the main island of Mauritius along with Rodrigues, Agalega, St Brandon, Tromelin and the Chagos Archipelago, while the Seychelles became a separate colony in 1906.The sovereignty of Tromelin is disputed between Mauritius and France as some of the islands such as St. Brandon, Chagos, Agalega and Tromelin were not specifically mentioned in the Treaty of Paris.
