Women's suffrage [SEP] Introduction
Women's suffrage is the right of women to vote in elections. Beginning in the mid-19th century, aside from the work being done by women for broad-based economic and political equality and for social reforms, women sought to change voting laws to allow them to vote. National and international organizations formed to coordinate efforts towards that objective, especially the International Woman Suffrage Alliance (founded in 1904 in Berlin, Germany), as well as for equal civil rights for women. Many instances occurred in recent centuries where women were selectively given, then stripped of, the right to vote. The first province in the world to award and maintain women's suffrage continuously, was Wyoming Territory in 1869, and the first sovereign nation was Norway in 1913.
