The joining of the Archdiocese of Russian Orthodox churches in Western Europe to the Moscow Patriarchate was the process of the Archdiocese of Russian Orthodox churches in Western Europe (AROCWE), formerly part of the Patriarchate of Constantinople, entering the jurisdiction of the Moscow Patriarchate. The decision to join the Moscow Patriarchate was not supported by all the clergy and laity of the archdiocese. Some parishes and clerics of the abolished Exarchate joined the local dioceses of the Patriarchate of Constantinople, as well as other local Eastern Orthodox churches.
