In one of the most violent strikes against a public utility in the United States, members of the Amalgamated Association of Street and Electric Railway Employees (AASERE) struck the Columbus Railway and Light Company for higher wages and union recognition on April 29, 1910. Violence flared after the company fired several union employees, and escalated with the arrival of 450 guards and strikebreakers from Cleveland. For ten weeks, more than 200 streetcars were idled and 24 were destroyed. More than 100 strikebreakers were injured. In July, the National Guard restored peace, but the strike did not subside until October 18, without recognition for the union.
