The Hasmonean dynasty was a ruling dynasty of Judea and surrounding regions during classical antiquity. Between c. 140 and c. 116 BCE the dynasty ruled Judea semi-autonomously from the Seleucids. From 110 BCE, with the Seleucid Empire disintegrating, the dynasty became fully independent, expanded into the neighbouring regions of Samaria, Galilee, Iturea, Perea, and Idumea, and took the title “basileus”. Some modern scholars refer to this period as an independent kingdom of Israel.
The dynasty was established under the leadership of Simon Thassi, two decades after his brother Judas Maccabeus (יהודה המכבי Yehudah HaMakabi) defeated the Seleucid army during the Maccabean Revolt. According to 1 Maccabees, 2 Maccabees, and the first book of The Jewish War by Jewish historian Flavius Josephus (37 CE–c. 100), Antiochus IV moved to assert strict control over the Seleucid satrapy of Coele Syria and Phoenicia after his successful invasion of Ptolemaic Egypt was turned back by the intervention of the Roman Republic. He sacked Jerusalem and its Temple, suppressing Jewish and Samaritan religious and cultural observances, and imposed Hellenistic practices. The ensuing revolt by the Jews (167 BCE) began a period of Jewish independence potentiated by the steady collapse of the Seleucid Empire under attacks from the rising powers of the Roman Republic and the Parthian Empire.
In 63 BCE, the kingdom was invaded by the Roman Republic, broken up and set up as a Roman client state. However, the same power vacuum that enabled the Jewish state to be recognized by the Roman Senate c. 139 BCE was later exploited by the Romans themselves. Hyrcanus II and Aristobulus II, Simon’s great-grandsons, became pawns in a proxy war between Julius Caesar and Pompey the Great. The deaths of Pompey (48 BCE) and Caesar (44 BCE), and the related Roman civil wars temporarily relaxed Rome’s grip on the Hasmonean kingdom, allowing a brief reassertion of autonomy backed by the Parthian Empire. This short independence was rapidly crushed by the Romans under Mark Antony and Octavian.
The dynasty had survived for 103 years before yielding to the Herodian dynasty in 37 BCE. The installation of Herod the Great (an Idumean) as king in 37 BCE made Judea a Roman client state and marked the end of the Hasmonean dynasty. Even then, Herod tried to bolster the legitimacy of his reign by marrying a Hasmonean princess, Mariamne, and planning to drown the last male Hasmonean heir at his Jericho palace. In 6 CE, Rome joined Judea proper, Samaria and Idumea (biblical Edom) into the Roman province of Judaea. In 44 CE, Rome installed the rule of a procurator side by side with the rule of the Herodian kings (specifically Agrippa I 41–44 and Agrippa II 50–100).
