Boulogne
The County of Boulogne was a French fief centred on the Channel port of Boulogne. In 1337 its child countess Joan I also ruled Auvergne.
Joan later married the future King John II of France. The La Tour d'Auvergne family succeeded in 1437, but Louis XI absorbed Boulogne into the royal domain in 1477; the Treaty of Senlis confirmed Habsburg renunciation in 1493.
