Although Susan B. Anthony worked on several local projects during this period, she remained deeply involved in national activities as president of the National American Woman Suffrage Association, working for an amendment to give women the right to vote. Generally known as the Anthony Amendment, it became the Nineteenth Amendment to the U.S. Constitution in 1920. When the Anthony sisters traveled to Berlin in 1904 for the founding of the International Woman Suffrage Alliance, Susan B. Anthony was declared its first member and Mary Anthony its second.
