Origins & Early Life

The Seleucid Empire ( sih-LEW-sid) was a Greek state in West Asia during the Hellenistic period. It was founded by the Macedonian general Seleucus I Nicator in 312 BC, following the division of Alexander the Great's Empire, and was ruled by the Seleucid dynasty from Seleucia and later Antioch until its annexation by the Roman Republic under Pompey in 63 BC. After receiving the Mesopotamian regions of Babylonia and Assyria in 321 BC, Seleucus I began expanding his dominions to include the Near Eastern territories that include modern Iraq, Iran, Afghanistan, Syria and Lebanon, all of which had been under Macedonian control after the fall of the former Achaemenid Empire. At the Seleucid Empire's height, it had consisted of territory that covered Anatolia, Persia, the Levant, Mesopotamia and what are now modern Kuwait, Afghanistan and parts of Turkmenistan in Central Asia. The Seleucid Empire was a center of Hellenistic culture.

Pivotal Works & Achievements

Greek customs and language were privileged; the wide variety of local traditions had been generally tolerated, while an urban Greek elite had formed the dominant political class and was reinforced by steady migration from Greece. The empire's western territories were repeatedly contested with Ptolemaic Egypt—a rival Hellenistic state. To the east, the Seleucid–Mauryan war with the Indian ruler Chandragupta of the Maurya Empire in 305 BC led to a political alliance and the cession of territories conquered by Alexander along the Indus River, east of Bactria. In the early second century BC, Antiochus III the Great fought the Roman–Seleucid war into Hellenistic Greece, but his attempts were thwarted by the Roman Republic and its Greek allies at the Battle of Magnesia. The Seleucids were forced to pay war reparations and had to relinquish territorial claims west of the Taurus Mountains in southern Anatolia, marking the gradual decline of the empire.

Enduring Legacy & Impact

Mithridates I of Parthia conquered much of the remaining eastern lands of the Seleucid Empire in the mid-second century BC, including Assyria and what had been Babylonia, while the independent Greco-Bactrian Kingdom continued to flourish in the northeast. The Seleucid kings were thereafter reduced to a rump state in Syria after a civil war, until their conquest by Tigranes the Great of Armenia in 83 BC, and ultimate overthrow by the Roman general Pompey in 63 BC. Contemporary sources, such as a loyalist decree honoring Antiochus I from Ilium, in Greek language define the Seleucid state both as an empire (ἀρχή, archḗ) and as a kingdom (βασιλεία, basileía). Similarly, Seleucid rulers were described as kings in Babylonia. The rulers did not describe themselves as being of any particular territory or people, but starting from the 2nd century BC, ancient writers referred to them as the Syrian kings, the kings of Syria or of the Syrians, the kings descended from Seleucus Nicator, the kings of Asia, and other designations.
