At what age do citizens gain the right to vote in the United States?

Citizens in the United States gain the right to vote at the age of 18, which is solidified in the 26th Amendment to the Constitution, ratified in 1971. This amendment was a significant milestone, as it ensured that all citizens, regardless of age, who are at least 18 years old, would have the opportunity to participate in the democratic process through voting.

This change reflected a societal belief that young adults, who could serve in the military and take on other adult responsibilities, should also have a say in the governance of their country. The emphasis on 18 as the voting age underscores the recognition of individuals at this age as mature enough to make informed decisions about their leaders and policies.

While there have been various voting age requirements at different times in U.S. history, including 21 in earlier periods, the establishment of 18 as the standard age for voting has remained since the amendment's ratification.
