Ukrainian Autocephalous Orthodox Church
The Ukrainian Autocephalous Orthodox Church is the smallest of the "big three" Orthodox Churches in Ukraine (the others being the Ukrainian Orthodox Church (Moscow Patriarchate), and the Ukrainian Orthodox Church (Kyivan Patriarchate)). This Church was created in 1921 by Ukrainian's, so that the "independant" Ukraine could have a fully Autocephalous Church. Many regard this Church as just a nationalistic institution.
In 1921 an All-Ukraine Sobor (Synod) created the Ukrainian Autocephalous Orthodox Church (UAOC) in Kiev and ordained Metropolitan Vasyl (Lypkivsky) as head of the UAOC. The UAOC was at that point independent of all other churches. It obtained its autocephalous status a few years later in 1924 when Gregory VII, Patriarch of Constantinople, Ecumenical Patriarch, issued a tomos re-establishing the Kievan Rus-Ukrainian) Metropolitan bishop see as an Autocephalous Church. The responsibility of establishing a new Synod of Bishops was given to the Metropolitan-Archbishop of Warsaw, Dionisij Waledynskyj.
In wake of the break up of the Russian Empire some national groups sought autonomy from Moscow. The Soviet government persecuted the UAOC; and the Russian Orthodox Church (ROC) also prevented the UAOC from establishing their ecclesiastical order for some time. Between the wars the UAOC was tolerated by the ROC and it was allowed to exist on Ukrainian Soviet territory.
On October 8, 1942 Archbishop Nikanor and Bishop Mstyslav of the UAOC and Metropolitan Oleksiy (Hromadsky) of the Ukrainian Autonomous Orthodox Church entered into an Act of Union at the Pochaev Lavra uniting these two church hierarchies. German occupation authorities and pro-Russian hierarchs of the Autonomous Church convinced Metropolitan Oleksiy to withdraw his signature. Metropolitan Oleksiy was executed in Volynia on May 7, 1943 by UPA insurgents.
The Russian Orthodox Church regained its general monopoly after World War II in the Ukrainian SSR. Most of the other churches were forced out as the Soviet government only recognized the Moscow Patriarchate, revived at the time of the Russian Revolution, as the only legitimate church in most of the Soviet Union. Many accused it of being a puppet of the Communist Party. After the suspicious death of Tikhon of Moscow these autocephalic churches sought to remain independent; something that Moscow tolerated until after World War Two when many Ukrainian Orthodox clergy not affiliated with Moscow fled to Germany or the United States. The UAOC in Ukraine was then liquidated by the Soviets with the assistance of the Patriarchate of Moscow. Any UAOC hierarchs or clergy who remained in Ukraine and refused to join the Russian Church were executed or sent to concentration camps. A few years later the same thing happened to the Ukrainian Greek Catholic Church in Western Ukraine and Transcarpathia.
Re-gaining the state recongnition in the late 1980s, the Church was initially ruled from abroad by Patriarch Mstyslav and then following his death in 1993 re-established itself as an independent church, following the brief union with the UOC-KP.
Geographically the church operates almost exclusively in the western Galcian provinces with minute support elsewhere. The church used to have a lot of parishes abroad in the Ukrainian emigre communities in Canada and in the United States. However, these parishes now form the separate churches (whom are now under the Ecumenical Patriarchate of Constantinople), the Ukrainian Orthodox Church of Canada and the Ukrainian Orthodox Church of the USA. There is a parish of the church in Canberra, Australia.
