The French language became an international language, the second international language alongside Latin, in the Middle Ages, "from the fourteenth century onwards". It was not by virtue of the power of the Kingdom of France: '"... until the end of the fifteenth century, the French of the chancellery spread as a political and literary language because the French court was the model of chivalric culture". Consequently, it was less as a centralising monarch than as a "gentle courtly prince" that the king unwittingly spread his language" and "the methods of expansion were not political"'. This status continued to grow into the 18th century, by which time French was the language of European diplomacy and international relations.
