Simon Thassi, and Simon's son, John Hyrcanus. The doctrine expressed in the book reflects traditional Jewish teaching, without later doctrines found, for example, in 2 Maccabees. The First Book of Maccabees also gives a list of Jewish colonies scattered elsewhere through the Mediterranean at the time. In the first chapter, Alexander the Great conquers the territory of Judea, and is later succeeded by the Seleucid Antiochus IV Epiphanes. After successfully invading the Ptolemaic Kingdom of Egypt, Antiochus IV captures Jerusalem and removes the sacred objects from the Temple in Jerusalem, slaughtering many Jews. He then imposes a tax and establishes a fortress in Jerusalem. Antiochus then tries to suppress public observance of Jewish laws, in an attempt to secure control over the Jews. In 168 BC, he desecrates the Temple by setting up an "abomination of desolation" (establishing rites of pagan observance in the Temple, or sacrificing an unclean animal on the altar in the Holy of Holies). Antiochus forbids both circumcision and possession of Jewish scriptures on pain of death. He forbids observance of the sabbath and the offering of sacrifices at the Temple. He also requires Jewish leaders to sacrifice to idols. While enforcement may be targeting only Jewish leaders, ordinary Jews were also killed as a warning to others. Hellenization included the construction of gymnasia in Jerusalem. Among other effects, this discouraged the Jewish rite of circumcision even further, which had already been officially forbidden; a man's state could not be concealed in the gymnasium, where men trained and socialized in the nude. However, 1 Maccabees also insists that there were many Jews who sought out or welcomed the introduction of Greek culture. According to the text, some Jewish men even engaged in foreskin restoration in order to pass as fully Greek. The narrative reports that news of the desolation reaches Mattathias and his five sons, a priestly family who live in Modein. Mattathias calls upon people loyal to the traditions of Israel to oppose the invaders and the Jewish Hellenizers, and his sons begin a military campaign against them. There is one complete loss of a thousand Jews (men, women, and children) to Antiochus when the Jewish defenders refuse to fight on the Sabbath. The other Jews then reason that, when attacked, they must fight even on the holy day. In 165 BC the Temple is freed and reconsecrated, so that ritual sacrifices may begin again.
