Malichus' reign is sometimes perceived as a period of declining Nabataean power, but this view depends in part on Nabataea having controlled Damascus in the period 34–40.[1][2][3] The Romans had, however, diverted the routes of spice and perfume cargo shipments to Egypt. Rome was very powerful, so Malichus cooperated. In 66, a Jewish revolt occurred in Judaea. Malichus sent 5,000 cavalry and 1,000 infantry to help the CaesarTitus crush the rebellion.
Malichus II died in AD 70,[4] and was succeeded by his son, Rabbel II Soter, initially under the regency of his widowed queen (and half sister by his fathers second marriage to Suqailat) Šagīlat II.
