The Territory of Wyoming passes the first law giving women over age 21 the right to vote. When Wyoming joins the Union in 1890, it becomes the first state to permit women the right to vote in all elections, although in 1887, Kansas permitted women to vote in municipal elections. In 1893, Colorado grants women the right to vote, followed by Utah and Idaho in 1896; Washington state in 1910; California in 1911; Oregon, Kansas and Arizona in 1912; Illinois in 1913; Montana and Nevada in 1914; New York in 1917; Michigan, South Dakota and Oklahoma in 1918.
