The Hasmonean dynasty (; Ḥašmōnaʾīm) was a ruling dynasty of Judea and surrounding regions during the Hellenistic times of the Second Temple period (part of classical antiquity), from BCE to 37 BCE. Between and BCE the dynasty ruled Judea semi-autonomously in the Seleucid Empire, and from roughly 110 BCE, with the empire disintegrating, Judea gained further autonomy and expanded into the neighboring regions of Perea, Samaria, Idumea, Galilee, and Iturea. The Hasmonean rulers took the Greek title basileus ("king") as the kingdom became a regional power for several decades. Forces of the Roman Republic intervened in the Hasmonean Civil War in 63 BCE and made it into a client state, marking the decline of Hasmonean dynasty; Herod the Great displaced the last reigning Hasmonean client-ruler in 37 BCE.
Simon Thassi established the dynasty in 141 BCE, two decades after his brother Judas Maccabeus ( Yehudah HaMakabi) had defeated the Seleucid army during the Maccabean Revolt of 167 to 141 BCE. According to 1 Maccabees, 2 Maccabees, and the first book of The Jewish War by historian Flavius Josephus (37 CE–), the Seleucid king Antiochus IV () moved to assert strict control over the Seleucid satrapy of Coele Syria and Phoenicia after his successful invasion of Ptolemaic Egypt (170–168 BCE) 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 ( 168–167 BCE). The steady collapse of the Seleucid Empire under attacks from the rising powers of the Roman Republic and the Parthian Empire allowed Judea to regain some autonomy; however, in 63 BCE, the kingdom was invaded by the Roman Republic, broken up and set up as a Roman client state.
Hyrcanus II and Aristobulus II, Simon's great-grandsons, became pawns in a proxy war between Julius Caesar and Pompey. 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, rapidly crushed by the Romans under Mark Antony and Augustus.
The Hasmonean 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 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).
Etymology
The family name of the Hasmonean dynasty originates with the ancestor of the house, whom Josephus Flavius called by the Hellenised form Asmoneus or Asamoneus (), said to have been the great-grandfather of Mattathias, but about whom nothing more is known. The name appears to come from the Hebrew name Hashmonay (חַשְׁמוֹנַאי Ḥašmōnaʾy). An alternative view posits that the Hebrew name Hashmona'i is linked with the village of Heshmon, mentioned in . Gott and Licht attribute the name to "Ha Simeon," a veiled reference to the Simeonite Tribe.
Background
The lands of the former Kingdom of Israel and Kingdom of Judah (–586 BCE), had been occupied in turn by Assyria, Babylonia, the Achaemenid Empire, and Alexander the Great's Hellenic Macedonian empire ( BCE), although Jewish religious practice and culture had persisted and even flourished during certain periods. The entire region was heavily contested between the successor states of Alexander's empire, the Seleucid Empire and Ptolemaic Egypt, during the six Syrian Wars of the 3rd–1st centuries BCE: "After two centuries of peace under the Persians, the Hebrew state found itself once more caught in the middle of power struggles between two great empires: the Seleucid state with its capital in Syria to the north and the Ptolemaic state, with its capital in Egypt to the south...Between 319 and 302 BC, Jerusalem changed hands seven times."
