4. Suffrage parade in New York City, 23 Oct. 1915. In the early 1900s, the struggle for woman suffrage became a mass and public movement. Suffragists organized highly visible and colorful events, such as this pre-referendum parade in which 20,000 women marched in clear order to send a clear message of their determined purpose.
