The Women's Trade Union League, established in 1903 in Boston, Massachusetts, was pivotal in reforming New York City and America itself in the aftermath of the Triangle Shirtwaist Factory Fire. This League, comprised of only a few hundred at the time, lobbied for legislative reforms such as shorter work hours and fire safety. It called many conferences, especially after the Triangle Shirtwaist Factory Fire, that led to the formation of committees that would prove to be critical in helping establish proper legislation. The WTUL was a proponent of the McManus Bill, which mandated regular fire drills, outward opening unlocked doors, adequate and accessible fire escapes, and expanded inspection requirements to enforce these new rules. It was critical in mobilizing people for protests, generally done in conjunction with other groups such as the International Ladies' Garment Workers' Union.
