In 1920, an international conference on passports and through tickets held by the League of Nations recommended that passports be issued in the French language, historically the language of diplomacy, and one other language. Currently, the ICAO recommends that passports be issued in English, French, and Spanish; or in the national language of the issuing country and in either English, French, or Spanish. Many European countries use their national language, along with English and French.
