Where did Russian orthodox Christianity begin?

Answer 1

The Eastern Orthodox (EO) Church was begun in Constantinople (Istanbul, Turkey) by Constantine of Rome. He ordered that Rome's Religion be changed from paganism to Christianity (at the time there was only gonna be one)

He gathered the numerous churches (i.e. Greek, Palestinean, Egyptian, Roman) and sat them down to form the new church traditions. This then became the Orthodox Church. This all occured around 350 AD. Around 1032 AD the Western Churches, (Rome, France, Spain) united and split from the Orthodox church to form a church with one head king. While the orthodox churches each had a king who met in a religious council to decide issues (religious republic). The new church in the west was eventually called the Holy See or Holy Catholic Church. Today Eastern Orthodoxy has spread and incorperated new churches like Brazil, Ethiopia, Kenya, Turkey, Russian, and more. The largest of which is Russian and today Constantiniple (Istanbul)is still the center of the eastern faith.
