It was the 44th state, admitted to the union in 1890.
Part of the reason Wyoming was granted statehood was that it was the first territory to grant women the right to vote. That happened in 1869, so you can see that it still took a while to become a state.
Wyoming has two nicknames: the Equality State and the Cowboy State. I'm sure you can guess why each one of those was chosen.
Wyoming is proud of its firsts. In addition to women's suffrage, it's the site of the first national park (Yellowstone in 1872) and the first national monument (Devils Tower in 1906). And in 1925 Nellie Tayloe Ross became Wyoming's -- and the nation's -- first woman governor.
