Lotta Continua
In 1969, the "operaismo" approach was active mainly in two different groups: "Lotta Continua", led by Adriano Sofri (which had a very significant Roman Catholic cultural matrix), and "Potere Operaio", led by Antonio Negri, Franco Piperno, Oreste Scalzone, and Valerio Morucci. Mario Capanna was the charismatic leader of the Milan student movement, which had a more classical Marxist-Leninist approach.
