Which amendment grants 18 year olds the right to vote?

The amendment that grants 18-year-olds the right to vote is the 26th Amendment to the United States Constitution. Ratified in 1971, this amendment lowered the voting age from 21 to 18, ensuring that younger citizens could participate in the electoral process. The motivation behind this change was largely influenced by the context of the Vietnam War, where young individuals were being drafted to fight but were not allowed to vote on the decisions affecting their lives.

This amendment represents a significant milestone in expanding democratic participation and recognizing the rights of younger citizens to engage in shaping their government. The passage of the 26th Amendment emphasized the principle that if individuals are deemed responsible enough to serve in the military and defend the nation, they should also have the right to vote and influence the governance of that nation.
