The Toledo Auto-Lite strike was a strike by a federal labor union of the American Federation of Labor (AFL) against the Electric Auto-Lite company of Toledo, Ohio, from April 12 to June 3, 1934. The strike is notable for a five-day running battle between roughly 6,000 strikers and 1,300 members of the Ohio National Guard. Known as the "Battle of Toledo," the clash left two strikers dead and more than 200 injured. The strike is regarded by many labor historians as one of the three most important strikes in U.S. history.
