Many people are familiar with how the Catholic Church persecuted Protestants, heretics, and other Catholics; but is there a similar history to the Orthodox Churches? Did the Orthodox persecute other groups (or even themselves)? I have no clue, I hope some of you can fill me in. Thanks.
Yes. Some of the main examples include (drawing from the entire history of the Eastern Church):
Persecution of Jews, pagans, and heretics (particularly Monophysites in Egypt) by Justinian and Heraclius (6th and 7th centuries)
Vicious persecution of the Paulicians and later Bogomils by the medieval Byzantine Empire
The persecution of the Old Believers in 17th-century Russia
Persecution of Stundists, Doukhobors, Molokans, and other dissenting groups in 19th-century Russia
Persecution of the “Lord’s Army” during the Communist years in Romania–admittedly the Communist government was the main actor here, but the Orthodox hierarchy stood back and even aided and abetted the persecution
Persecution of Byzantine Catholics in several Eastern European countries, including Romania (the one I know best)
Discrimination against various non-Orthodox groups, especially “neo-Protestant sects,” in post-Communist Orthodox countries (in Romania, mob violence against Baptists is fairly common in the more rural areas, or was in the 90s)
