Eastern Orthodoxy by country
Based on the numbers of adherents, the Eastern Orthodox Church (also known as Eastern Orthodoxy) is the second largest Christian communion in the world after the Roman Catholic Church. The most common estimates of the number of Eastern Orthodox Christians worldwide is approximately 200–260 million. The numerous Protestant groups in the world, if taken all together, outnumber the Eastern Orthodox, but they differ theologically and do not form a single communion.
History of the Eastern Orthodox Church
Although many of them have adopted Lamaism – which is the mainstream form of Tibetan Mahayana Buddhism – the Evenks of both the Russian Federation and the People's Republic of China are a nominally Orthodox Christian people. Along with their Evenks cousins and a few other tribes in Siberia or in China, they are some of the only Asiatic peoples who nominally practice Orthodox Christianity, which they had voluntarily (as opposed to being coerced to do so) adopted during contacts from Russian expansion into Siberia.
