France also ceded the eastern half of French Louisiana to Britain; that is, the area from the Mississippi River to the Appalachian Mountains. France had already secretly given Louisiana to Spain in the Treaty of Fontainebleau (1762), but Spain did not take possession until 1769. Spain ceded East Florida to Britain. In addition, France regained its factories in India but recognized British clients as the rulers of key Indian native states and pledged not to send troops to Bengal. Britain agreed to demolish its fortifications in British Honduras (now Belize) but retained a logwood-cutting colony there. Britain confirmed the right of its new subjects to practise Catholicism.
