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).
The Albany Plan of Union was a plan to place the British North American colonies under a more centralized government. The plan was adopted on July 10, 1754, by representatives from seven of the British North American colonies. Although never carried out, it was the first important plan to conceive of the colonies as a collective whole united under one government.
