Between 1890 and the start of World War I in 1914, there were very significant developments in the efforts to secure woman suffrage.
On the national scene two rival factions — the National Woman Suffrage Association and the American Woman Suffrage Association — merged on Feb. 18, 1890 into the National American Woman Suffrage Association.
Several factors contributed to this merger. Elizabeth Cady Stanton, Susan B. Anthony and Lucy Stone were getting older and were replaced by new emerging leadership — Carrie Chapman Catt, Anna Howard Shaw, Harriot Eaton Stanton Blatch and later Alice Paul. Another factor was that the nation in 1890 was far different from 1848.
