The Orthodox civilization consists of Armenia, Belarus, Bulgaria, Cyprus, Georgia, Greece, Moldova, Montenegro, Republic of Macedonia, Romania, Russia, Serbia and Ukraine.
Orthodoxy is considered a distinctive civilization of its own. Orthodoxy is an Eastern branch of Christianity, which was separated from Western Christianity early in history in a schism, and developed in its own unique way. Orthodox people have Orthodoxy as their religion, and live in Russia and parts of Eastern Europe.
The civilization was separated from Western Europe ever since it was being invaded in the Middle Ages. Hence, the orthodox civilization had never been through The Renaissance or The Reformation, which had brought much change to the Western world.
It inherited its orthodox culture from the Byzantium Empire, when Ivan the Great married the niece of Constantine XI, the last Byzantine emperor. Russia adopted the two-headed eagle of Byzantium as their emblem. Russia considered them self the Third Rome (second being the Byzantium Empire).
Orthodox Christianity from the Byzantium Empire was earlier adopted as the religion of Russians. Being isolated from the West and directly controlled by Tatars from the East, the Russians and Eastern Europeans developed a brand new culture consisting of pieces of Western and Eastern culture.
