Despite problems with the NAWSA, the early 20th century was a time of great political activity for women. Many women initiated reform movements to address problems associated with urbanization, industrialization, and mass immigration. Women joined reform clubs and lived in settlement houses, such as the Hull House, founded by Jane Addams, in Chicago.
Many women sought to pass reform legislation. Over time, they realized that women would be better able to lobby politicians to pass reform legislation if women exercised the right to vote. Thus, women in the reform movement gradually became committed to winning the right to vote. By the end of the first decade of the 20th century, woman suffrage had become a mass political movement for the first time.
