The conflict in Northern Ireland was one of the most devastating in post-war Europe, claiming the lives of 3,500 people and injuring many more. This book is a riveting new history of the radical politics that drove a unique insurgency that emerged from the crucible of 1968. Based on extensive archival research, One Man's Terrorist explores the relationship between the IRA, a clandestine army described as 'one of the most ruthless and capable insurgent forces in modern history', and the political movement that developed alongside it to challenge British rule. From Wilson and Heath to Thatcher and Blair, a generation of British politicians had to face an unprecedented subversive threat whose reach extended from West Belfast to Westminster.
