Fifth Syrian War
The Fifth Syrian War was fought from 203 to 195 B.C. when Antiochus III conspired with Philip V of Macedon to strip the Ptolemaic Empire of most of its holdings due to the recent death of Ptolemy IV and the accession of the infant Ptolemy V to the throne. In Palestine and Syria Antiochus was successful with the crowning victory coming at the Battle of Panium. Philip was less successful being repulsed by Pergamum and Rhodes, both allies of the Egyptian Ptolemys and on sea he was defeated in the naval Battle of Chios in 201 B.C. He then became involved in the disastrous Second Macedonian War with Rome and was too busy to fight further.
