The Moratorium to End the War in Vietnam was a national series of protests and teach-ins against the Vietnam War that began on this day in 1967. One politician noted it was the first time anti-war protests reached the level of a mass movement.

This protest was followed a month later by a large Moratorium March in Washington, D.C. Socialist politician Fred Halstead wrote that it was "the first time [the anti-war movement] reached the level of a full-fledged mass movement."

Over a quarter of million people attended the Moratorium march in Washington, D.C., where they marched down Pennsylvania Avenue in the evening bearing candles led by Coretta Scott King to the White House. Scott King told the marchers that it would have delighted her assassinated husband, Martin Luther King Jr., to have seen people of all races rallying together for the cause of peace.

Rallies held in New York, Detroit, Boston (where about 100,000 attended a speech by anti-war Senator George McGovern), and Miami were also well attended.
