Bousies was part of
County of Hainaut, an enclave in
Cambrésis of which it was one of the 12 peerages. In 1007, Jean, Lord of Bousies, as peer of Cambrésis, pledged fidelity to
bishop Herbin Ist, Count of Cambrai. In 1095, the bishop Gaucher put the castle of Bousies under siege, and lord Wiband helped by a few locals resisted for 3 days before the castle was taken and later destroyed. Rebuilt, it was again taken in 1185 and in 1665. Later, it was purchased by French statesman
Marshal Mortier to be used as a hunting place. Sadly, its inheritors sold it to wreckers who destroyed it for building materials. Joseph-Gaspard de Tascher,
Napoleon III's Maternal Great-grandfather, was born in Bousies. The family of Bousies became prominent in Scotland and can still be found in parts of Northern Ireland, but under the name of Bowsie after George Bousie changed the spelling in the 1800s because he didn't like the spelling of his surname. Another branch of the family emigrated to Belgium, in the Hainaut Province and later to Flanders, where they can still be found today. ==Population==
