The women's suffrage movement fought to gain women the right to vote, which they lacked during colonial times when only adult male property owners could vote. As more women became educated and involved in reform movements in the early 19th century, they and their supporters called suffragists began questioning why women could not also vote. Though some men harassed and intimidated suffragists, the women continued their struggle and achieved the right to vote with the 19th amendment in 1920.
