In 1958, the Independent Socialist League led by Max Shachtman dissolved to join the Socialist Party of America. Shachtman had written that Soviet communism was a new form of class society, bureaucratic collectivism, in which the ruling class exploited and oppressed the population and therefore he opposed the spread of communism. Shachtman also argued that democratic socialists should work with activists from labor unions and civil rights organizations to help build a social democratic "realignment" of the Democratic Party. Though he died on November 4, 1972, and had little involvement with the Socialist Party in the year proceeding his death, his followers, identitified as "Shachmanites", exercised a tremendous amount of influence on the party.
