The Herodian dynasty was a royal dynasty of Idumaean (Edomite) descent, ruling the Herodian Kingdom and later the Herodian Tetrarchy, as vassals 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 long Hasmonean Kingdom. His kingdom lasted until his death in 4 BCE, when it was divided between his sons as a Tetrarchy, which lasted for about 10 years.
