Temperance movement. They were instrumental in the passage of the 18th Amendment in 1920, which prohibited the sale and consumption of alcohol.
I attended UC Berkeley from September, 1965 to January, 1966 and I spent a lot of time on Sproul Plaza getting involved with different progressive and revolutionary groups.
Some groups involved in the 60’s civil rights struggle were:
CORE (Congress Of Racial Equality).
Martin Luther King Jr’s group, the SCLC (Southern Christian Leadership Conference).
Stokely Carmichael’s group, the SNCC (Student Nonviolent Coordinating Committee), which was more militant than CORE and SCLC.
Even more militant than any of the above was RAM, the Revolutionary Action Movement. They eschewed the pacifist approach of the above civil rights groups (derisively referring to them as “civil rites”), and said that blacks should arm themselves to fight their racist oppressors.
Some of the Marxist groups on campus:
YSA (Young Socialist Alliance). They were the student division of the Socialist Workers’ Party and claimed to be adherents of Leon Trotsky. While they opposed the Stalinist governments of the USSR, China, North Korea, and North Vietnam, they supported the Stalinist government of Fidel Castro in Cuba.
Spartacist League. They were another and more militant Trotskyist group. They criticized the YSA for supporting Castro, and said all of the Stalinist governments needed overthrowing.
Independent Socialist Club. They claimed that Marx would have opposed the Bolshevik Revolution, because Russia was still a primarily agrarian country and therefore had not undergone the prerequisite transition to a capitalist economy.
Progressive Labor Movement. A Maoist (Stalinist) group that was strongly aligned with Mousey Tongue (aka Mao Zedong), who was the leader of Communist China from 1949–1976.
Communist Party (Marxist–Leninist): These guys were hyper-militantly Stalinist-Maoist. A YSA member told me they tried to give some YSA literature to a CP M-L. Instead of saying, “No thanks.”, the intended recipient snarled in reply, “I don’t read Trotskyite garbage!”.
