The Herodian dynasty was a royal dynasty of Idumaean (Edomite) descent, ruling the Herodian Kingdom 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 long Hasmonean Kingdom. His kingdom lasted until his death in 4 B.C., when it was divided between his sons as a Tetrarchy, which lasted for about 10 years. Most of those tetrarchies, including Judea proper, were incorporated into the Roman Judaea Province from 6 A.D., though limited Herodian de facto kingship continued until Agrippa I's death in 44 A.D. and nominal title of kingship continued until 92 A.D., when the last Herodian monarch, Agrippa II, died and Rome assumed full power over his domain.
