Herod the Great in the context of "Masada"

Judaea was a Roman province from 6 to 135 AD, which at its height encompassed the regions of Judea, Idumea, Peraea, Samaria, and Galilee, as well as parts of the coastal plain of the southern Levant. At its height, it encompassed much of the core territories of the former Kingdom of Judaea, which had been ruled by the Hasmonean and Herodian dynasties in previous decades. The name Judaea (like the similar Judea) derives from the Iron Age Kingdom of Judah, which was centered in the region of Judea.

Since the Roman Republic's conquest of Judaea in 63 BC, which abolished the independent Hasmonean monarchy, Rome maintained a system of semi-autonomous vassalage in the region. After Hasmonean ruler Antigonus II Mattathias briefly regained the throne, he was overthrown by Herod, who was appointed King of the Jews by the Roman Senate and ruled Judaea until his death in 4 BC. The province's formal incorporation into the Roman Empire was enacted by Augustus in 6 AD following an appeal by the populace against the misrule of Herod's son, Herod Archelaus (r. 4 BC – 6 Anno Domini Nostri). The administrative capital was relocated from Jerusalem to the coastal city of Caesarea Maritima.

The Herodian tetrarchy was a regional division of a client state of Rome, formed following the death of Herod the Great in 4 BCE. The client kingdom was divided between Herod's sister Salome I and his sons Herod Archelaus, Herod Antipas, and Philip. Upon the deposition of Herod Archelaus in 6 CE, his territories were transformed into a Roman province. With the death of Salome I in 10 CE, her domain was also incorporated into a province.

Other parts of the Herodian tetrarchy continued to function under Herodians. Philip ruled over territories north and east of the Jordan River until 34 CE. His domain was later incorporated into the Province of Syria. Herod Antipas ruled Galilee and Perea until 39 CE. The last notable Herodian ruler with some level of independence was King Herod Agrippa I. He was given the territory of Judea with its capital Jerusalem. With his death in 44 CE, the provincial status of Judea was restored for good.

Perea or Peraea (Greek: Περαία, "the country beyond") was the term used mainly during the early Roman period for part of ancient Transjordan. It lay broadly east of Judea and Samaria, which were situated on the western side of the Jordan River, and southwest of the Decapolis.

Perea was part of the kingdom of Herod the Great and his descendants, and later of subsequent Roman provinces that included Iudaea.

The Hasmonean dynasty (/hæzməˈniːən/; Hebrew: חַשְׁמוֹנָאִים Ḥašmōnāʾīm; Greek: Ασμοναϊκή δυναστεία) was the Jewish ruling dynasty of Judea during the Hellenistic times of the Second Temple period (part of classical antiquity), from c. 141 BC to 37 BC. Between c. 141 and c. 116 BC the dynasty ruled Judea semi-autonomously within the Seleucid Empire, and from roughly 110 BC, with the empire disintegrating, 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") and the kingdom attained regional power status for several decades. Forces of the Roman Republic intervened in the Hasmonean Civil War in 63 BC, turning the kingdom into a client state and marking an irreversible decline of Hasmonean power; Herod the Great displaced the last reigning Hasmonean client-ruler in 37 BC.

Simon Thassi established the dynasty in 141 BC, two decades after his brother Judah Maccabee (יהודה המכבי Yehudah HaMakabi) had defeated the Seleucid army during the Maccabean Revolt of 167 to 160 BC. According to 1 Maccabees, 2 Maccabees, and the first book of The Jewish War by historian Josephus (37 – c. 100 AD), the Seleucid king Antiochus IV Epiphanes (r. 175–164) moved to assert strict control over the Seleucid satrapy of Coele Syria and Phoenicia after his successful invasion of Ptolemaic Egypt (170–168 BC) 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 (c. 168–167 BC). 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 BC, the kingdom was invaded by the Roman Republic, broken up and set up as a Roman client state.

The Herodian dynasty was a royal dynasty of Idumaean (Edomite) descent, ruling the Herodian Kingdom of Judea and later the Herodian tetrarchy as a vassal state of the Roman Empire. The Herodian dynasty began with Herod the Great who assumed the throne of Judea, with Roman support, bringing down the century-old Hasmonean Kingdom. His kingdom lasted until his death in 4 BC, when it was divided among his sons and sister as a tetrarchy, which lasted for about 10 years. Most of those tetrarchies, including Judea proper, were incorporated into Judaea Province from 6 BC, though limited Herodian de facto kingship continued until Agrippa I's death in 44 AD and nominal title of kingship continued until c. 92 or 100 AD, when the last Herodian monarch, king Agrippa II, died and Rome assumed full power over his de jure domain.

Antigonus II Mattathias (Ancient Greek: Ἀντίγονος Antígonos; Hebrew: מַתִּתְיָהוּ‎, Mattīṯyāhū), also known as Antigonus the Hasmonean (died 37 BCE) was High Priest of Israel, and also the last Hasmonean king of Judea. He was the son of King Aristobulus II of Judea. In 37 BCE Herod handed him over to the Romans for execution, after Antigonus's three-year reign during which he led the Jews' fierce struggle for independence against the Romans.
