Gods at War examines the role played by religions in starting or supporting wars from ancient Egypt and Israel to the current conflicts in Yemen and the Ukraine. It not only analyses the traditionally recognised wars of religion such as the Crusades and the Thirty Years War and the many Islamic jihads, but also addresses the role played by nearly all religions in encouraging warrior kings, dictators and even democracies to wage wars, supporting them with money, promises of paradise in the after-life, guarantees of victory (God is on their side) and ceremonial to keep up morale.
