"History of Woman Suffrage, Volume I" by Elizabeth Cady Stanton, Susan B. Anthony, and Matilda Joslyn Gage is a historical work published in 1881. Spanning over 5700 pages across six volumes, this monumental project documents the women's suffrage movement from its beginnings through 1920. Written from the perspective of Stanton and Anthony's wing of the movement, it compiles letters, speeches, newspaper clippings, and court documents. The work preserves primary sources of a struggle its authors called "the most momentous reform that has yet been launched on the world."
