Abstract
This chapter discusses the history of the practice of strategy from Antiquity to the First World War. After introducing the reader to the various definitions of strategy, the chapter considers sources of Antiquity about warfare, from ancient Greece and Rome to the time of Rome’s Constantinopolitan (Byzantine) successors, Justinian I and Heraclius. It then examines episodes of European history since Antiquity for which historians claim to have found evidence of the practice of strategy. In particular, it looks at the West European Middle Ages, which saw the rise of complex decision-making involving multiple tools—strategy. It also analyses the transformation of warfare and of strategy in early modern Europe, covering case studies that span the wars involving Philip II of Spain, Louis XIV of France, and Frederick II of Prussia, as well as the American War of Independence and the Napoleonic Wars.
