Quizplus · Accepted Answer

The minimum age at which an American may vote was lowered from 21 years old to 18 in 1971. The shift resulted primarily from the anti-war demonstrations of the 1960s and the response to the Vietnam War Draft, which drafted men who were 18 and older. Many activists championed the position that it was unfair to send soldiers to fight in a war when they had no say in the governance of the country for which they fought.
