Perea (region)

Perea or Peraea (Greek: Περαία, "the country beyond"), was the portion of the kingdom of Herod the Great occupying the eastern side of the Jordan River valley, from about one third the way down from the Sea of Galilee to about one third the way down the eastern shore of the Dead Sea; it did not extend very far to the east. Herod the Great's kingdom was bequeathed to four heirs, of which Herod Antipas received both Perea and Galilee. He dedicated the city Livias in the north of the Dead Sea. In 39 CE, Perea and Galilee were transferred from disfavoured Antipas to Agrippa I by Caligula. With his death in 44 CE, Agrippa's merged territory was made province again, including Judaea and for the first time, Perea. From that time Perea was part of the shifting Roman provinces to its west: Judaea, and later Syria Palaestina, Palaestina and Palaestina Prima. Attested mostly in Josephus' books, the term was in rarer use in the late Roman period. It appears in Eusebius' Greek language geographical work, Onomasticon, but in the Latin translation by Jerome, Transjordan is used.

Gadara of Perea (identified as Tell Jadur near Al-Salt ) was the chief city or metropolis of Perea (not to be confused with Gadara of the Decapolis−a Hellenistic city). Following the Roman conquest of Judea led by Pompey in 63 BCE, Aulus Gabinius, proconsul of Syria, split the former Hasmonean Kingdom into five districts of legal and religious councils known as Sanhedrin and based at Jerusalem, Jericho, Sepphoris (Galilee), Amathus (Perea) and Gadara (Perea—Al-Salt or Decapolis—Umm Qais).
