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. Journals like "Radical America" and "Black Mask" in America, "Solidarity", "Big Flame" and "Democracy & Nature", succeeded by "The International Journal of Inclusive Democracy", in the UK, introduced a range of left libertarian ideas to a new generation. Social ecology, autonomism and, more recently, participatory economics (parecon), and Inclusive Democracy emerged from this.
