Which of the following countries was the last to allow women to vote?

Women's suffrage is the right of women to vote in elections. Beginning in the mid-19th century 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.

The first province to continuously allow women to vote was the Pitcairn Islands in 1838, and the first sovereign nation was Norway in 1913. During World War I, Denmark, Canada, Russia, Germany, and Poland also recognized women's right to vote.

Since Saudi Arabia granted voting rights to women (2015), women can vote in every country that has elections.
