The festival of Hanukkah is instituted by Judas Maccabeus and his brothers to celebrate this event (1 Maccabees 4:59). More wars involving Judas and his brothers Simon and Jonathan are reported in chapters 5, 6 and 7. Chapter 6 reports the last days of Antiochus Epiphanes and the accession of his young son Antiochus V Eupator to the throne. In chapter 8, Judas seeks an alliance with the Roman Republic, aiming to remove the Greeks. Verses 23–32 record an agreement between Rome and the nation of the Jews, whereby each party would act as a willing ally of the other and refuse to supply their enemies in time of war, specific warning being given to Demetrius I Soter that this pact would be activated against him if requested by the Jews. Jewish historian asserts that "the majority of scholars today accept the authenticity of this document". After the death of Judas and a period of lawlessness, he is succeeded by his brother Jonathan Apphus, whose battles with the Greek general Bacchides are recounted in chapter 9. Jonathan becomes high priest (1 Maccabees 10:20). Demetrius' death is reported in 1 Maccabees 10:50, and Ptolemy VI Philometor and Alexander Balas, claimant to the Seleucid throne, enter into an agreement under which Alexander marries Cleopatra Thea, Ptolemy's daughter (1 Maccabees 10:58). The relationship between Jonathan and Demetrius' son and successor, Demetrius II Nicator, is covered in chapter 11: Jonathan provides military support to Demetrius at the latter's request (verse 44), and a successful engagement against a popular revolt at Antioch enables the Jews to "gain glory in the sight of the king" (verse 51). Maccabees does not mention the involvement of the mercenaries who are mentioned in other accounts, whereas other accounts do not mention the Jewish involvement. Ultimately the relationship between Jonathan and Demetrius breaks down: Maccabees' opinion is that Demetrius "broke his word about all that he had promised; he became estranged from Jonathan and did not repay the favors that Jonathan had done him, but treated him very harshly". Proposed alliances with Rome and with Areus of Sparta are covered in 1 Maccabees 12:1–23. Jonathan's capture in 143 BC, having been double-crossed by Diodotus Tryphon, is recorded in 1 Maccabees 12:48. Simon follows Jonathan as the next Jewish leader "in place of Judas and your brother Jonathan", taking on civil, military and liturgical roles: "great high priest, governor, and leader
