 The emergence of the New Left in the 1950s and 1960s led to a revival of interest in libertarian socialism.The New Left's critique of the Old Left's authoritarianism was associated with a strong interest in personal liberty, autonomy (see the thinking of Cornelius Castoriadis) and led to a rediscovery of older socialist traditions, such as left communism, council communism, and the Industrial Workers of the World.The New Left also led to a revival of anarchism.
