Answer:
anytime before 1919
Explanation:
1919 was when the 19th amendment, the women's right to vote, was added to the constitution. so women were not able to vote before 1919. this was unfair because men were able to vote but women were not allowed to.
this shows the unfair treatment of women as they were treated as less than men until 1919 (because they were not allowed to vote).
