On this day, 12 January 1919 workers and university students in Lima, Peru, walked out on a mass general strike for a maximum 8-hour working day. Although the government arrested and tortured anarcho-syndicalist strike leaders, the stoppage and street clashes continued for 3 days until the government caved in.
