Seleucid dynasty
The Seleucid dynasty or the Seleucidae was a Macedonian Greek royal family, which ruled the Seleucid Empire based in West Asia during the Hellenistic period. It was founded by Seleucus I Nicator, a general and successor of Alexander the Great, after the division of the Macedonian Empire as a result of the Wars of the Successors.
Through its history, the Seleucid dominion included large parts of the Near East, as well as of the Asian territory of the earlier Achaemenid Persian Empire. A major center of Hellenistic culture, it attracted a large number of immigrants from Greece who, encouraged by the Seleucids, formed a dominant political elite under the ruling dynasty. After the death of Seleucus I, his successors maintained the empire's strength establishing it as a Greek power in West Asia; the empire reached its height under emperor Antiochus III. From the mid-second century BC, after its defeat at the hands of the resurgent Parthian Empire, the polity entered a state of instability with slow territorial losses and internecine civil wars. The Seleucids, now reduced to a rump state occupying a small part of Syria succumbed to the Roman Republic's annexation of their territory in 64 BC under Pompey the Great.
History
Background
served as an officer of Alexander the Great, commanding the elite infantry corps in the Macedonian army: the "Shield-bearers", later known as the "Silvershields". After the death of Alexander in 323 BC, the Partition of Triparadisus assigned Seleucus as satrap of Babylon in 321 BC. Antigonus, the satrap of much of Asia Minor, forced Seleucus to flee from Babylon, but, supported by Ptolemy, the Satrap of Egypt, Seleucus returned in 312 BC. Seleucus' later conquests included Persia and Media. He agreed to a peace treaty with the Indian King Chandragupta Maurya. Seleucus defeated Antigonus in the Battle of Ipsus in 301 BC and Lysimachus in the battle of Corupedium in 281 BC. Ptolemy Ceraunus assassinated Seleucus later in the same year. Seleucus' eldest son Antiochus I succeeded him as ruler of the Seleucid territories in 281 BC.Seleucid rulers
