{{Main|True Orthodoxy}}
Starting in the 1920s, [[Greek Old Calendarists|parallel hierarchies]] formed in opposition to local Orthodox churches over ecumenism and other matters. These jurisdictions sometimes refer to themselves as being "True Orthodox". In Russia, underground churches formed and maintained solidarity with the Russian Orthodox Church Outside Russia until the late 1970s. There are now traditionalist Orthodox in every area, though in Asia and Egypt their presence is negligible.
