The story of the 100 most influential weapons in history. Our history has been shaped and changed by weapons: the smallest advances in weapons development have helped to build and overthrow empires, changed the course of civilization, driven modern technology, and won wars. For thousands of years, individual pieces of weaponry have come to symbolize struggles and nations, from the Roman gladius to the English longbow, and from the flintlock musket through to the AK47. This book reveals the weapons that had the greatest impact on our history, explaining how and why they came to prominence, and uncovers the lasting effect they had on the world.
