The Seleucid dynasty or the Seleucidae (from Greek: Σελευκίδαι, Seleukídai) was a Greek Macedonian royal family, founded by Seleucus I Nicator (“the Victor”), which ruled the Seleucid Empire centered in the Near East and regions of the Asian part of the earlier Achaemenid Persian Empire during the Hellenistic period.
Seleucus (ca. 358 – 281 BCE) served as an officer of Alexander the Great, commanding the élite infantry corps in the Macedonian army: the “Shield-bearers” (Hypaspistai), later known as the “Silvershields” (Ἀργυράσπιδες / Argyraspides) metal water jug. After the death of Alexander in 323 BCE, the Partition of Triparadisus assigned Seleucus as satrap of Babylon in 321 BCE. 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 BCE. Seleucus’ later conquests included Persia and Media. He formed an alliance with the Indian King Chandragupta Maurya (reigned 324-297 BCE). Seleucus defeated Antigonus in the Battle of Ipsus in 301 BCE and Lysimachus (King of Thrace waterproof cellphone bag, Macedon and Asia Minor) in the battle of Corupedium (near Sardis) in 281 BCE. Ptolemy Ceraunus assassinated Seleucus later in the same year. Seleucus’ eldest son Antiochus I succeeded him as ruler of the Seleucid territories.
