The history of Eastern Orthodox Christian theology begins with the life of Jesus and the forming of the Christian Church. Major events include the Chalcedonian schism of 451 with the Oriental Orthodox miaphysites, the Iconoclast controversy of the 8th and 9th centuries, the Photian schism (863-867), the Great Schism (culminating in 1054) between East and West, and the Hesychast controversy (c. 1337-1351). The period after the end of the Second World War in 1945 saw a re-engagement with the Greek, and more recently Syriac Fathers that included a rediscovery of the theological works of St. Gregory Palamas, which has resulted in a renewal of Orthodox theology in the 20th and 21st centuries.
