The Shiners' Wars were violent outbreaks in Bytown (now Ottawa) from 1835 to 1845 between Irish-Catholic immigrants, led by Peter Aylen, and French Canadians, led by Joseph Montferrand. The war began when Aylen, a major Irish timber operator, organized a group of Irishmen to attack other timber operations—this group was known as the "Shiners." The Shiners attacked French-Canadian timber rafts and the town's political institutions, as well as brawling with French Canadians on the streets. In an attempt to control the violence, the citizens of Bytown created the Association of the Preservation of the Public Peace in Bytown, which included armed patrols; however, the violence continued. In the spring of 1837, the violence was brought under control after the government deployed troops to arrest the Shiners. Occasional violence still occurred until 1845 by groups claiming to be the Shiners.
