The history of the Eastern Orthodox Church is the formation, events, and transformation of the Eastern Orthodox Church through time. According to the Eastern Orthodox tradition, the history of the Eastern Orthodox Church is traced back to Jesus Christ and the Apostles. The Apostles appointed successors, known as bishops, and they in turn appointed other bishops in a process known as Apostolic succession. Over time, five Patriarchates were established to organize the Christian world, and four of these ancient patriarchates remain Orthodox today. Orthodox Christianity reached its present form in late antiquity, when the ecumenical councils were held, doctrinal disputes were resolved, the Fathers of the Church lived and wrote, and Orthodox worship practices settled into their permanent form.
