A History of War explains the dark but compelling story of warfare, from its emergence in prehistoric tribal disputes, through great imperial and global wars, to present-day counterinsurgency and ''hybrid'' conflicts. Two factors sit at the heart of this story: technology - including weapons, vehicle systems, vehicles and tactics. A History of War charts the rise of the army, explaining how primitive tribal war parties evolved through seasonal levies and feudal armies to professional standing armies and mass conscription forces, with formal organisational structures. The narrative of A History of War is sewn together by the conflicts that have periodically reshaped history and created the roots of current conflict, from the crusades and two world wars to Cold War and the conflicts in the Middle East. The book provides summaries and insights into these disputes while recognising the human drama of conflict, with first-hand insight into the experience of combat.
