which amendment lowered the voting age to 18

The amendment that lowered the voting age to 18 in the United States is the Twenty-sixth Amendment. It was ratified on July 1, 1971, and it legally established that citizens 18 years of age or older have the right to vote, which could not be denied or abridged by the United States or any state on account of age. Before this amendment, the minimum voting age was 21 years. The push to lower the voting age was significantly influenced by the Vietnam War and the military draft age being set at 18, which led to the popular slogan "old enough to fight, old enough to vote".
