The Hasmonean dynasty was a ruling dynasty of Judea and surrounding regions during the Hellenistic times of the Second Temple period, from c. 140 BCE to 37 BCE. Between c. 140 and c. 116 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.

Judea or Judaea is a mountainous region of the Levant. Traditionally dominated by the city of Jerusalem, it is now part of Palestine and Israel. The name's usage is historic, having been used in antiquity and still into the present day; it originates from Yehudah, a Hebrew name. Yehudah was a son of Jacob, who was later given the name "Israel" and whose sons collectively headed the Twelve Tribes of Israel. Yehudah's progeny among the Israelites formed the Tribe of Judah, with whom the Kingdom of Judah is associated. Related nomenclature continued to be used under the rule of the Babylonians, the Persians, the Greeks, and the Romans. Under the Hasmoneans, the Herodians, and the Romans, the term was applied to an area larger than the historical region of Judea. In 132 CE, the Roman province of Judaea was merged with Galilee to form the enlarged province of Syria Palaestina.
