The Rent Strike is a method of protest commonly employed against large landlords.
Generally a group of tenants come together and refuse payment until a specific demand is met.
It an be a useful tactic as a last resort.
In 1915 there was a massive rent strike in Glasgow. One of the leaders was Mary Barbour. She and an "army" of supporters pelted bailiffs trying to enter tenements with flour bombs. In the end the Government relented and on 27 November 1915 legislation was introduced restricting rents to the pre-war level.
Sean Damer (1996) compares the 1915 rent strikes to the struggles in the late 1980s and early 1990's against the poll tax. Both are depicted as popular movements championing justice.
