Alexander the Great founded numerous settlements on his military campaigns (map pictured), during which he created one of the largest empires in history. His settlements have been the subject of intense debate, as the accounts of historical scholars differ wildly and are often contradictory. Plutarch provides the maximum estimate of seventy cities in his Life of Alexander, but most texts attest to between ten and twenty foundations, which Alexander named after himself or his close companions. The accounts of Alexander's campaigns, primarily those of Arrian, Plutarch, Diodorus, Curtius Rufus, and Justin, help to provide evidence. The most important of the settlements he founded include Alexandria in Egypt, Boukephala and Nikaia on the Indus River, Alexandria Eschate in Central Asia, and Alexandria Ariana in modern Afghanistan.
