The rise of the worldwide anti-globalization movement has led to a renewed interest in anarchism, but many are still unsure of what it is that anarchists stand for. In this clear and penetrating study, Ruth Kinna goes right to the heart of the ideology, explaining the influences that have shaped anarchism, and the tactics and strategies that anarchists have used to bring about their goals. Drawing on a wide range of sources, from the classic accounts of Kropotkin and Bakunin to the work of modern anarchist thinkers, this insightful work will provide the perfect introduction to anarchism, the anti-globalization movement and the issue of whether anarchist ideals can ever be consistent with justifying violence for political ends.
