Christianity becoming a state religion and seperation of east- west churches

Christianity, which emerged under the leadership of Jesus Christ in the Palestinian geography, when Judaism was widespread, has attracted attention in every geography since the time it started to spread with it's different discourses and it's unique belief system. The history of Christianity started to follow in the other direction after meeting with the Roman Empire and becoming the official religion of this empire. From this date on, the Christian belief has started to be mentioned with the Roman Empire and has been studied as a whole by both religious history researchers and Byzantine history researchers. Especially with the tolerance policy of Constantine the Great, the spread of Christianity in the Roman Empire and the process of becoming the official religion of the empire with Theodosios the Great was the beginning of the events to be experienced in this religion. As a result of these events that became apparent since 313, different views emerged in the Christian faith and these differences of opinion turned into sectarian conflicts over time. As a result, what happened between the Orthodox and Catholic sects, which emerged with the excommunication of two churches in 1054 and is an unsolved issue even today, is among the most important events in world history. The events between these two Christian churches have been an issue that changed the political, social and economic structure of the Byzantine Empire and occupied Europe for centuries.
