In the early ‘60s and into the ‘70s, Americans of many backgrounds were unified over a shared opposition to the Vietnam War. The most well-known demonstration for many is the Kent State University protest where four students were killed by the Ohio National Guard on May 4, 1970. Among the many forms of resistance during this time, the most enduring product of this movement is the United States voting age being lowered from 21 to 18 years of age.
