Human history - from the empires of the ancient world to the superpowers of the 21st century - has been inextricably shaped by conflict and the weapons that have been used to wage it. The technologies that have produced advanced civilizations have also been harnessed to the grim business of warfare. This short history, stretching from the chariot to the Stuxnet virus which disabled Iran's nuclear enrichment programme in 2007, charts some of the most significant weapons, fortifications and tactics that have been developed in the last 2,500 years.
