Question

What type of event led to the growth of the International Ladies' Garment 'Workers' Union?

Answer 1

The Triangle shirtwaist fire.

Explanation:

On March 25 1911 a fire at the Triangle Factory in New York City saw the death of 146 women, many of whom jumped to their death to avoid being consumed by the fire.

Unions in general were extremely weak in the early 20th Century but this tragedy so polarized people over the horror of the fire that ILGWU quickly gained purchase with those employed in the industry.
