In November 1920, after the final defeat of the Russian Army in South Russia, a number of Russian bishops evacuated from Crimea to Constantinople, then occupied by British, French, and Italian forces. After learning that General Pyotr Wrangel intended to keep his army, they likewise decided to keep the Russian ecclesiastical organization as a separate entity abroad. The Temporary Church Authority met on 19 November 1920 aboard the ship "Grand Duke Alexader Mikhailovich" (), presided over by Metropolitan Antony (Khrapovitsky). Metropolitan Antony and Bishop Benjamin (Fedchenkov) were appointed to examine the canonicity of the organization. On 2 December 1920, they received permission from Metropolitan Dorotheos of Prussia, Locum Tenens of the Ecumenical Patriarchate of Constantinople, to establish "for the purpose of the service of the population [...] and to oversee the ecclesiastic life of Russian colonies in Orthodox countries a temporary committee (epitropia) under the authority of the Ecumenical Patriarchate"; the committee was called the Temporary Higher Church Administration Abroad (THCAA).
