Today is May Day, also known as International Worker's Day. The first May Day was celebrated here, in America -- with a parade led by one of my personal heroes, anarcho-communist Lucy Parsons -- to commemorate the Haymarket affair . Long story very short, there were protests following an incident at a Chicago factory where striking workers were killed by police. Although they were mostly peaceful, someone threw a bomb (we still don't know who) and eight anarchists, including Parsons' husband Alfred, were found guilty of "conspiracy." Four of them were hanged, and the rest were later pardoned by the governor. While it's still a significant day for laborers across the world, America decided to celebrate its Labor Day in September in order to distance the holiday from its radical roots.
