The emergence and rise of the Pirate Parties across Europe remains an under-studied phenomenon, despite it being one of the rare new transnational movements that succeeded in establishing itself in several countries, with Pirate Parties registered in a total of 62 countries. This book offers a detailed analysis of the emergence and rise of Pirate politics across Europe, from 2005 to 2015. Based on a thorough content analysis of official Pirate Parties documents across Europe and interviews with key members of this movement, the book offers a balanced mix between theoretical and practical chapters. It shows how throughout the early 2010s, Pirate Parties have played key roles in transnational anti-austerity and anti-Transatlantic Trade and Investment Partnership (TTIP) movements. Most importantly, it demonstrates how Pirate Parties in Sweden, Germany and Iceland became influential on the national and European stages. This text will be of key interest to students and scholars of political parties and party politics, European politics, comparative politics and more broadly to the social sciences and law.
