This book raises the question of how the Church of England, in its role as an established church, has responded to British military interventions since the early 1950s. It asks questions about how Anglicans have participated in debates over war, what they have been saying, and whether they have been able to influence public discussion or policy. Of particular concern is how or whether religious establishment continues to give them a degree of access to policy makers not available to other religious groups, and whether this brings with it constraints as well as advantages. After raising these questions, the introduction offers a brief overview of how the Church of England engages in the public sphere and how this has evolved over time, before looking at the wider foreign policy context within which church leaders operate.
