Many maps reveal that the Ard[dubious – discuss] of Batanea was at the east of the Leja region[1] (the common Herodian Trachonitis).
Today, as it was during Greco-Roman times, Batanaea is more commonly considered to be the area east of the Leja.
In the 1st century BCE, the land was acquired by Herod the Great, who established a community of Jews from Babylon who were brought to Batanaea for the purpose of maintaining order against the banditry of the Trachonites.
[3] Upon Herod's death in 4 BCE, Batanaea passed to his son Philip as part of his inheritance.
In some sources, Philip is referred to as the "Tetrarch of Batanea" with the capital at Caesarea Philippi, although his lands were more extensive than this.
