Antiochus III (father of Antiochus Epiphanes) (Daniel 11:10-19).
‘And his sons will be stirred up (or ‘will strive' or ‘will make war') and will gather a multitude of great forces, and he will relentlessly come on, and overthrow, and pass through. And he will return and make war (or ‘be stirred up'), even to his fortress.'
First Seleucus II's son, Seleucus III, who succeeded his father on his death in 227 BC, and then when he died not many years later in 223 BC, his brother Antiochus III, were ‘kings of the north'. Both of these sons sought to restore the glory of the Syrian empire, and they mustered their forces and went out raiding in various directions. Seleucus III invaded Asia Minor, and Antiochus III later attacked Egypt (‘his' probably refers to Egypt) and the fortress was probably Gaza, giving him control of Palestine, for although Antiochus III did not invade Egypt proper, he was successful during his campaign of 219-217 BC in gaining control of Israel. Egypt's northern border had until then been Syria, but Antiochus III succeeded in driving the Egyptians, then under Ptolemy IV, back to the southern borders of Israel. He earned the epitaph "the Great" because of his military successes.
But the important thing about this was that it meant that Israel for the first time came under the control of the Syrian empire, the Seleucids. It was to be crucial to their future, especially as outlined by Daniel.
