who was the first martyr and how were they persecuted
Christian martyrs Religious martyrdom is considered one of the more significant contributions of Second Temple Judaism to western civilization. It is believed that the concept of voluntary death for God developed out of the conflict between King Antiochus Epiphanes IV and the Jewish people. 1 Maccabees and 2 Maccabees recount numerous martyrdoms suffered by Jews resisting the Hellenizing of their Seleucid overlords, being executed for such crimes as observing the Sabbath, circumcising their children or refusing to eat pork or meat sacrificed to foreign gods. With few exceptions, this assumption has lasted from the early Christian period to this day, accepted both by Jews and Christians.
Constantine the Great and Christianity Constantine's decision to cease the persecution of Christians in the Roman Empire was a turning point for early Christianity, sometimes referred to as the Triumph of the Church, the Peace of the Church or the Constantinian shift. In 313, Constantine and Licinius issued the Edict of Milan decriminalizing Christian worship. The emperor became a great patron of the Church and set a precedent for the position of the Christian emperor within the Church and the notion of orthodoxy, Christendom, ecumenical councils, and the state church of the Roman Empire declared by edict in 380. He is revered as a saint and isapostolos in the Eastern Orthodox Church, Oriental Orthodox Church, and various Eastern Catholic Churches for his example as a "Christian monarch."
