The Twenty-Sixth Amendment

Section 1. The right of citizens of the United States, who are eighteen years of age or older, to vote shall not be denied or abridged by the United States or by any State on account of age. Section 2. The Congress shall have the power to enforce this article by appropriate legislation.

The Twenty-sixth Amendment limited the minimum voting age to no more than 18. It was adopted in response to student activism against the Vietnam War.
