Libertarianism
Contemporary libertarian socialism

A surge of popular interest in libertarian socialism occurred in Western nations during the 1960s and 1970s. Anarchism was influential in the counterculture of the 1960s and anarchists actively participated in the protests of 1968 which included students and workers' revolts. In 1968, the International of Anarchist Federations was founded in Carrara, Italy during an international anarchist conference held there in 1968 by the three existing European federations of France, the Italian and the Iberian Anarchist Federation as well as the Bulgarian Anarchist Federation in French exile.

Around the turn of the 21st century, libertarian socialism grew in popularity and influence as part of the anti-war, anti-capitalist and anti-globalisation movements. Anarchists became known for their involvement in protests against the meetings of the World Trade Organization (WTO), Group of Eight and the World Economic Forum. Some anarchist factions at these protests engaged in rioting, property destruction and violent confrontations with police. These actions were precipitated by ad hoc, leaderless, anonymous cadres known as black blocs and other organizational tactics pioneered in this time include security culture, affinity groups and the use of decentralized technologies such as the Internet. A significant event of this period was the confrontations at WTO conference in Seattle in 1999. For English anarchist scholar Simon Critchley, "contemporary anarchism can be seen as a powerful critique of the pseudo-libertarianism of contemporary neo-liberalism. One might say that contemporary anarchism is about responsibility, whether sexual, ecological or socio-economic; it flows from an experience of conscience about the manifold ways in which the West ravages the rest; it is an ethical outrage at the yawning inequality, impoverishment and disenfranchisment that is so palpable locally and globally". This might also have been motivated by "the collapse of ' really existing socialism ' and the capitulation to neo-liberalism of Western social democracy ".

Since the end of the Cold War, there have been at least two major experiments in libertarian socialism: the Zapatista uprising in Mexico, during which the Zapatista Army of National Liberation (EZLN) enabled the formation of a self-governing autonomous territory in the Mexican state of Chiapas; and the Rojava Revolution in Syria, which established the Autonomous Administration of North and East Syria (AANES) as a "libertarian socialist alternative to the colonially established state boundaries in the Middle East."

In 2022, student activist and self-described libertarian socialist Gabriel Boric became head of state of Chile after winning the 2021 Chilean presidential election with the Apruebo Dignidad coalition.
