What significant action did Wyoming take concerning women's rights?

Wyoming is historically significant for being the first U.S. territory to grant women the right to vote, which it did in 1869. This milestone was a crucial step in the women's suffrage movement and highlighted Wyoming's progressive stance on women’s rights for its time. Allowing women to vote was not just about providing a voice in electoral matters; it symbolized broader recognition of women’s roles in society and allowed for a greater push toward gender equality.

While the other actions listed are important in the context of women's rights, they either occurred later or were not specific to Wyoming’s early accomplishments. Wyoming's early suffrage law set a precedent that would encourage other states to follow suit, ultimately culminating in the constitutional right to vote for women nationwide with the 19th Amendment in 1920.
