September 16, 1920
Manhattan, New York City, New York
A horse-drawn wagon carrying 100 lbs. of dynamite and 500 lbs. of cast iron shrapnel explodes in front if the J.P. Morgan bank on Wall Street, killing 38 people as well as the horse carrying the bomb, and injuring 143
The bombing was believed to be carried out by Galleanist anarchists, a group of anarchists who followed Luigi Galleani. Galleani was an Italian anarchist living in the United States who advocated “propaganda of the deed,” using violence to attemp to overthrow governments and tyrants. The attack is thought to be in retaliation to Galleani being deported.
The attack killed 38 people, most of whom were younger people working as messengers, couriers, clerks, brokers, and stenographers. At the time of the attack, it was the deadliest act of terrorism in the United States, surpassing the 21 deaths of the Los Angeles Times bombing in 1910. The Bath School disaster in 1927 which claimed the lives of 44 victims, in turn, surpassed the Wall Street Bombings.
