In the 20th century leadership of the suffrage movement passed to two organizations. The first, the National American Woman Suffrage Association (NAWSA), under the leadership of Carrie Chapman Catt, was a moderate organization. The NAWSA undertook campaigns to enfranchise women in individual states, and simultaneously lobbied President Wilson and Congress to pass a woman suffrage Constitutional Amendment. In the 1910s, NAWSA’s membership numbered in the millions.
