As a result of France's extensive colonial ambitions between the 17th and 20th centuries, French was introduced to the Americas, Africa, Polynesia, South-East Asia, as well as the Caribbean. French is the second most studied foreign language in the world after English, and is a lingua franca in some regions, notably in Africa. The legacy of French as a living language outside Europe is mixed: it is nearly extinct in some former French colonies (The Levant, South and Southeast Asia), while creoles and pidgins based on French have emerged in the French departments in the West Indies and the South Pacific (French Polynesia). On the other hand, many former French colonies have adopted French as an official language, and the total number of French speakers is increasing, especially in Africa.
