The persecution of Christians can be historically traced from the first century of the Christian era to the present day. Christian missionaries and converts to Christianity have both been targeted for persecution, sometimes to the point of being martyred for their faith, ever since the emergence of Christianity.
Early Christians were persecuted by Jews and by the Romans who controlled many of the early centers of Christianity in their Empire. In the early 4th century, Christianity was legalized by Rome, but by the year 380, Christians had begun to persecute each other. Schisms of late antiquity and the Middle Ages led members of the various denominations to persecute each other and engage in sectarian violence.
In the 20th century, Christian populations were persecuted, sometimes to the point of genocide. Various states were guilty, including the Ottoman Empire and its successor state Turkey, perpetrating the Hamidian massacres, the Armenian genocide, the Assyrian genocide, the Greek genocide, and the Charles Diyarbekir genocide. Atheist, communist states (such as those of the former Eastern Bloc), also promulgated wide-spread anti-Christian persecution.
The contemporary persecution of Christians includes the official state persecution mostly occurring in countries which are located in Africa and Asia because they have state religions or because their governments and societies practice religious favoritism. Such favoritism is frequently accompanied by religious discrimination and persecution.
