King of Babylonia (145-141). Known as Nicator (“victor”) and son of Demetrius I, Demetrius II rose in revolt against Alexandre I in 147 B.C.E. with support of Ptolemaic Egypt. Successful, Demetrius ascends to the throne in 145. However, the debilitated condition of the Seleucid kingdom allows little resistance to Parthian expansion. After the loss of Seleucia-on-the-Tigris, Uruk (141) and Susa (139) Demetrius is himself taken captive by Parthian forces in 138. Demetrius II is the last Seleucid king to be mentioned in the Babylonian King List of the Hellenistic Period.
