Seventeenth: Allowed for regular citizens to vote for their United States Senators, instead of having the state legislature do it.
Nineteenth: Said that civilians could not be prohibited to vote based off of their gender, or in causal terms, gave women the right to vote.
Twenty-Third: Gave the area in which the seat of the government was in (District of Columbia) the right to vote.
Twenty-Fourth: Abolished the "poll taxes," which was a fare that governments required citizens to pay to be able to cast their vote.
