Seleucus I Nicator

Seleucus I Nicator (Greek: Σέλευκος Νικάτωρ, Séleukos Nikátōr, "Seleucus the Victorious"; c. 358 BC – 281 BC) was a Macedonian Greek general, officer and successor of Alexander the Great who went on to found the eponymous Seleucid Empire, led by the Seleucid dynasty. Initially a secondary player in the power struggles following Alexander's death, Seleucus rose to become the total ruler of Asia Minor, Syria, Mesopotamia, and the Iranian plateau, assuming the title of basileus (king). The Seleucid Empire was one of the major powers of the Hellenistic world, until it was overcome by the Roman Republic and Parthian Empire in the late second and early first centuries BC. While serving under Alexander, Seleucus was commander of the Hypaspistai, an elite Macedonian infantry unit.
