How long did it take for women to win the right to vote?

The answer

New Zealand became the first self-governing country to grant women the right to vote in 1893, but most nations took decades longer. In the United States, the 19th Amendment wasn't ratified until 1920 after a 72-year campaign beginning at the 1848 Seneca Falls Convention. Britain granted partial women's suffrage in 1918 and full equal voting rights in 1928. France didn't follow until 1944, and Switzerland - often seen as a bastion of democracy - waited until 1971 at the federal level.
