Book excerpt: This book analyses how humour in political activism contributes to facilitating outreach, mobilisation and the sustaining of cultures of resistance. Drawing on examples of attention-grabbing stunts from around the world, Humour in Political Activism demonstrates how they succeed in turning relations of power upside down. The ambiguity and unpredictability of humour, Sørensen argues, makes it difficult to respond to this form of political activism when it is performed in public. Humorous political stunts can therefore challenge state power, help influence changes in law and make significant contributions to the conversations about how societies should be organised. The book also investigates the potential risks and limitations of using humour in nonviolent action and what makes humour unique compared with other forms of non-humorous political activism.
