The annual marches began in 1886 when more than 300,000 people in the United States ditched work to protest in favor of an eight-hour work day, a battle that had began two years earlier.

Two days after the May Day strike, police fired upon another protest at a Chicago factory and killed four people. The next day people gathered in Haymarket Square to protest the killings.

When officers arrived and began to disperse the crowd, a bomb was thrown at the police — killing one immediately. Â Seven more died from injuries over the following weeks.

Eight anarchists were convicted of murder for the bombings, though they maintained their innocence. Four of the men were hanged and another took his own life by placing an explosive in his mouth. The remaining three were pardoned six years later.
