These statements explain what happened during the Haymarket Square incident.
Step-by-step explanation:
The Haymarket Riot that occurred on May 4, 1886 has become a historic representation of the struggle for worker’s rights. The aim of the strike was to demand for an eight hours work per working day, so a group of anarchists announced a peaceful gathering at Haymarket Square, which is said to have crowded 1,500 people.
As the police tried to interfere to separate the workers and diverse the protest, a bomb was thrown from an unknown person, leading to seven police officers and one civilian being killed as well as several injured.
The demand for justice rose right after the incident, and eight men who were known as anarchists and were said to have organized the strike, were arrested with no actual evidence. After the illegal conviction of the eight men, four of them were hung, one kills himself, while the three others were pardoned after spending seven years in jail.
