Anarchism is a political tradition that unites a number of different anti-authoritarian currents and is seen as an alternative to the Leninist tradition. However, anarchism itself has been divided historically, to an extent over the ultimate goal, but largely over important issues of political analysis, strategy and tactics. The situation is the same today. This session will look at the distinct tradition of communist anarchism to explore how it is both similar and different to other currents. Some of these differences are far from trivial and often put our current in opposition to those who have been grouped under what we call big tent anarchism. It is not a question of sectarianism, as we work with a wide range of anarchists in grass roots campaigns and projects, but with how we can best build an effective revolutionary anarchist movement. The issues we will discuss are not just of interest to anarchists. Questions such as the role of organisation, insurrectionism, analysis of class, freedom and collective responsibility, attitude towards Labour, support for national liberation are relevant to all who are concerned with social transformation. We will address these questions in the context of specific contexts, from the Russian Revolution to today’s pandemic.
