Overview
The County of Boulogne was a countship within the Kingdom of France, founded in 896 CE and centered on the city of Boulogne-sur-Mer. During the 10th century, it was ruled by the counts of Flanders, but an independent House of Boulogne emerged in the 11th century. In 1212, it was merged into the County of Artois by Philip II of France, and later annexed to the royal domain in 1477. The county was dissolved in 1501 CE.
