When Patriarch Tikhon died in 1925, the Soviet authorities forbade patriarchal election. Patriarchal "locum tenens" (acting Patriarch) Metropolitan Sergius (Stragorodsky, 1887–1944), going against the opinion of a major part of the church's parishes, in 1927 issued a declaration accepting the Soviet authority over the church as legitimate, pledging the church's cooperation with the government and condemning political dissent within the church. By this declaration Sergius granted himself authority that he, being a deputy of imprisoned Metropolitan Peter and acting against his will, had no right to assume according to the XXXIV Apostolic canon, which led to a split with the Russian Orthodox Church Outside Russia abroad and the Russian True Orthodox Church (Russian Catacomb Church) within the Soviet Union, as they allegedly remained faithful to the Canons of the Apostles, declaring the part of the church led by Metropolitan Sergius schism, sometimes coined "Sergianism". Due to this canonical disagreement it is disputed which church has been the legitimate successor to the Russian Orthodox Church that had existed before 1925.
