The Vietnam era was marked by student anti-war protests and the counterculture movement. But in 1970 the "silent majority" organized the era's largest pro-war demonstration, simultaneously protesting against President Nixon's Vietnam War policies and "hippies and yippies everywhere."

Jeannette Rankin

The Jeannette Rankin Brigade

In 1916, Jeannette Rankin made history as the first woman elected to Congress. A renowned pacifist, Rankin was the only member of Congress to vote against U.S. involvement in World War II. At age 87, Rankin made one final push for peace by leading an anti-Vietnam march: the Jeannette Rankin Brigade.

May 1970: College Park Explodes

The May 4, 1970 antiwar protest at Kent State University in Ohio, in which National Guard troops fired into a crowd of demonstrators protesting the Nixon Administration's invasion of Cambodia and shot four of them dead, was a traumatic event that burned itself into the American collective memory.  A photo of a teenage girl crying out in shock over the body of one of the slain students became, for many, the iconic image that captured a frighteningly turbulent time.

But it's almost forgotten that the University of Maryland's flagship campus in College Park was rocked by a protest that was bigger and possibly more raucous than the one at Kent State.

Arlington's First Official Unknown Soldier

At Arlington National Cemetery, the subject of a new WETA program that premieres Feb. 5 at 8 p.m., one of the most haunting features is the Tomb of the Unknowns, also known as the Tomb of the Unknown Soldier.

On the rear of the monument, there's a haunting inscription: Here rests in honored glory, an American soldier known but to God.

But the story of how the first official unknown soldier from World War I was selected for burial in the graves alongside the monument is a strange one. For one, he wasn't actually the first unidentified casualty to be entombed at Arlington.
