Define "Swing" riot.
The Swing Riots got their name from the deliberately cryptic message "Lord John Russell Swing" which was scrawled on the walls of rural homes by protesting agricultural laborers in 1830s England, during the riots. The message was intended to be a coded call to action for other laborers to join the protest against low wages and poor working conditions.
