Which amendment guarantees that citizens eighteen years and older can vote?

The Twenty-sixth Amendment guarantees that citizens who are eighteen years and older have the right to vote. Ratified in 1971, this amendment was primarily a response to the argument that if individuals were old enough to be drafted for military service, they should also have the right to participate in the electoral process. By lowering the voting age from twenty-one to eighteen, the amendment aimed to enfranchise younger voters and ensure that they could have a say in the policies that affect their lives.

The other amendments listed serve different purposes: the First Amendment deals with the freedoms of speech, religion, press, assembly, and petition; the Nineteenth Amendment grants women the right to vote; while the Twenty-fourth Amendment prohibits the use of poll taxes in federal elections. Each of these amendments tackles significant civil rights issues, but it is the Twenty-sixth Amendment that specifically addresses voting rights for those eighteen and older.
