Seleucus I Nicator 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. In the power struggles that followed Alexander's death, Seleucus rose from being a secondary player to becoming the total ruler of Asia Minor, Syria, Mesopotamia, and the Iranian plateau, assuming the title of basileus (emperor). 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, or Silver-Shields, an elite Macedonian infantry unit. After the death of Alexander in June 323 BC, Seleucus initially supported Perdiccas, the regent of Alexander's empire, and was appointed Commander of the Companions and chiliarch at the Partition of Babylon in 323 BC. However, after the outbreak of the Wars of the Diadochi in 322, Perdiccas' military failures against Ptolemy in Egypt led to the mutiny of his troops in Pelusium. Perdiccas was betrayed and assassinated in a conspiracy by Seleucus, Peithon and Antigenes in Pelusium sometime in either 321 or 320 BC. At the Partition of Triparadisus in 321 BC, Seleucus was appointed Satrap of Babylon under the new regent Antipater. But almost immediately, the wars between the Diadochi resumed and one of the most powerful of the Diadochi, Antigonus, forced Seleucus to flee Babylon. Seleucus was only able to return to Babylon in 312 BC with the support of Ptolemy. From 312 BC, Seleucus ruthlessly expanded his dominions and eventually conquered the Persian and Median lands. Seleucus ruled not only Babylonia, but the entire eastern part of Alexander's empire. Seleucus further made claim to the former satrapies in Gandhara and in eastern India. However these ambitions were contested by Chandragupta Maurya, resulting in the Seleucid–Mauryan War (305–303 BC). The conflict was ultimately resolved by a treaty resulting in the Maurya Empire annexing the eastern satrapies. Additionally, a marriage alliance was formed, with Chandragupta marrying a daughter of Seleucus, according to Strabo and Appian. Furthermore, the Seleucid Empire received a considerable military force of 500 war elephants with mahouts, which would play a decisive role against Antigonus at the Battle of Ipsus in 301 BC.
