1971: North Carolina becomes the 38th state to ratify the 26th Amendment to the U.S. Constitution, reducing the voting age from 21 to 18, thereby putting the amendment into effect. The ratification process took three months and eight days from the time the amendment was submitted to the states, making this amendment the quickest to be ratified.
