Caesar was assassinated in 44 BCE and unrest and confusion spread throughout the Roman world, including Judaea. Antipater the Idumean was assassinated in 43 BCE by the Nabatean king, Malichus I, who had bribed one of Hyrcanus’ cup-bearers to poison and kill Antipater. However, Antipater's sons managed to maintain their control over Judea and their father's puppet Hasmonean, Hyrcanus.
