The Seattle General Strike of 1919 began as a shipyard strike on January 21st, 1919 involving 30,000 union members demanding higher wages. As labor conditions worsened after World War I with layoffs and declining wages, frustration among laborers grew. By February 6th, the strike had expanded to a general strike involving over 50,000 people shutting down the city of Seattle. The strike ended on February 11th without major demands being met, partly due to pressure from the military presence in Seattle supporting a return to work. Though inconclusive, the week-long general strike demonstrated the growing power of organized labor and was an important event in the history of labor movements in the United States.
