The Triangle Shirtwaist Factory Fire was regarded as one of the most terrible events in American History during the Industrial Revolution. 123 immigrant women and 23 men were killed due to the fire on March 25, 1911.
The aftermath was horrific as safety regulations were either ignored or failed, leading to the death of these women and men.
Many of the girls jumped 9 floors down to their death, others were burned alive, and some suffocated from the smoke caused by the fire.
The outcome of this fire led to many movements to try and change how factories were handled as well as widespread attention to the dangerous sweatshop conditions of factories.

“ of the most infamous incidents in American industrial history, as the deaths were largely preventable... The tragedy brought widespread attention to the dangerous sweatshop conditions... and led to the development of a series of laws and regulations that better protected the safety of workers.”
