Rabel II Soter (ar-Rabil) was the last ruler of the Nabataean kingdom, ruling from 70 to 106.
After the death of his father, Malichus II, ar-Rabil still a child, ascended to the throne. His mother, Shaqilath, assumed control of the government in the early years. His sister Gamilath became queen of the Nabataeans. Ar-Rabil gave himself the Greek title "Soter", meaning "Savior", or "the one who has given life and deliverance to his people".
After his death in 106, the Roman emperor Trajan faced practically no resistance and conquered the kingdom on 22 March 106. It became the Roman province of Arabia Petraea, with Bosra becoming its provincial capital.
