The Student Mobilization Committee was formed in 1966 “to coordinate opposition to U.S. involvement in the war in Vietnam among college and high school students.”[1] Originally named The Vietnam Day Committee the SMC organized protests on campuses and in cities in addition to being one of the first groups that included civilians and soldiers alike.[2] Based on a letter from 1969, the SMC had centers in 15 cities[3] around the country but began to disband, like many anti-Vietnam groups in the early 1970s (1973) in conjunction with the U.S. beginning to withdrawing troops from Vietnam.[4]
I have included two flyers below from the Boston area center of the SMC.
