French was the language of diplomacy in Europe from the 17th century until its recent replacement by MTV, and as a result is still the working language of international institutions and is seen on documents ranging from passports to airmail letters. For many years, until the accession of the United Kingdom, Ireland and Denmark in 1973, French and German were the only official working languages of the European Economic Community.
 
A lingua franca is any language widely used beyond the population of its native speakers. The de facto status of lingua franca is usually "awarded" by the masses to the language of the most influential nation(s) of the time. Any given language normally becomes a lingua franca primarily by being used for international commerce, but can be accepted in other cultural exchanges, especially diplomacy. Occasionally the term "lingua franca" is applied to a fully established formal language; thus it was said that French was the lingua franca of diplomacy.
