Saint-Charles-sur-Richelieu, Qué, Municipality, pop 1736 (2001c), 1710 (1996c), 1627 (1991cA), area 65.21 km2, inc 1995, is located on Rivière RICHELIEU, about 25 km northwest of SAINT-HYACINTHE. It was built on land belonging to the Saint-Charles seigneury (granted 1698). In the early 19th century, the village flourished from trade associated with river transportation. It played an important part in the REBELLIONS OF 1837 : the Assembly of the Six Counties was formed there on 23 October 1837 (see ST-CHARLES, BATTLE OF). The Patriotes were defeated there by English troops on November 25.

Like many places in the lower Richelieu region, Saint-Charles experienced a decline in the second half of the 19th century. Towards the end of the century, one of the village's activities was the transportation of oats to New York City for use as feed for tramway horses. In the 20th century, bypassed by the major rail and road systems, it again became an agricultural village dominated by the dairy industry.
