County of Boulogne

The County of Boulogne was a medieval territory in what is now northern France, centered around the town of Boulogne-sur-Mer. Established in the 10th century, it became significant due to its strategic location on the English Channel. The county was ruled by counts who were often involved in regional power struggles and alliances, particularly with England. Boulogne played a key role in trade, military campaigns, and the broader political landscape of the time, serving as a bridge between France and England during periods of conflict and cooperation, especially during the Crusades and the Hundred Years' War.
