all but collapsed in the wake of the Seleucid defeat. The Hellenizing High Priest Menelaus was removed from office and executed. His successor was another Hellenizer Alcimus. When Alcimus executed sixty priests who were opposed to him, he found himself in open conflict with the Maccabees. Alcimus fled from Jerusalem and went to the Seleucid king, asking for help. Meanwhile, Demetrius I Soter, son of Seleucus IV Philopator and nephew of the late Antiochus IV Epiphanes, fled from Rome in defiance of the Roman Senate, arrived in Syria. Declaring himself the rightful king, he captured and killed Lysias and Antiochus Eupator, taking the throne. It was thus Demetrius to whom the delegation led by Alcimus, complained of the persecution of the Hellenist party in Judea. Demetrius granted Alcimus's request to be appointed High Priest under the protection of the king's army and sent to Judea an army led by Bacchides. The weaker Jewish army couldn't oppose the enemy and withdrew from Jerusalem, so Judah returned to wage guerrilla warfare. Soon after, it was necessary for the Seleucid Army to return to Antioch because of the turbulent political situation. Judah's forces returned to Jerusalem and the Seleucids dispatched another army, again led by Nicanor.

It was the first recorded contract between the Jewish people and the Romans. The agreement with Rome failed to have any effect on Demetrius' policy. On receipt of the news of Nicanor's defeat, he dispatched a new army, again commanded by Bacchides. This time the Seleucid forces of 20,000 men were numerically so superior that most of Judah's men left the field of battle and advised their leader to do likewise and to await a more favorable opportunity. However, Judah decided to stand his ground. In the Battle of Elasa, Judah and those who remained faithful to him were killed. His body was taken by his brothers from the battlefield and buried in the family sepulchre at Modiin. The death of Judah Maccabee (d. 160 BCE) stirred the Jews to renewed resistance.
