Creation On 20 September 1918, the
Local Council of the Russian Orthodox Church "for the sake of resolving difficulties on the path to unity and to possibly facilitate [...] the achievement of the ultimate goal" (that is, restoring unity and communication) instructed the Synod to form a standing commission under the Synod with branches in Russia and far abroad to interact with non-Eastern-Orthodox churches. However, it was not possible to establish that Commission. On 4 April 1946, by decision of the
Holy Synod of the Russian Orthodox Church, the Department for external church relations was formed and had as its goal "the management of foreign institutions of the Russian Orthodox Church (dioceses, parishes, exarchates, metropolitan districts, spiritual missions, etc.; relations with
autocephalous Eastern Orthodox Churches; correspondence with foreign institutions; processing of foreign correspondence: translation into Russian, preparation of answers, preparation of archival and scientific references; preparation of reports on all fundamental issues arising in connection with the management of foreign institutions, the relationship of the Russian Church with other autocephalous Churches and the leadership of non-Eastern-Orthodox religions". Initially, the department had a small staff; along with Metropolitan Nicholas, the first employee of the department was (
clerk since May 1946). According to David Gzgyan, member of the : "under the new Patriarch,
Alexy I, in 1945 a special body was created in the structure of the Moscow Patriarchate: the Department for External Church Relations [...] since then, its head has been the 'person number two' of the Russian Orthodox Church. This situation is unique in the whole history of the church throughout the world: the key role in the activities of the Church belonged to the department of external relations, which normally should occupy the most modest place. Today, the DECR, of course, is not the same, but the general veil of "special status" remains. In the second half of the 1940s, the Department was allocated colossal funds to carry out numerous contacts with the Middle Eastern patriarchates and churches of Europe, including non-Eastern-Orthodox (for example,
Anglican). In addition, it was given a large-scale task: to create an anti-
Vatican block." The work to strengthen the department in 1960-1961 was carried out by the under the
Council of Ministers of the USSR, "fulfilling the decision of the
Central Committee of the CPSU of July 25, 1960." In accordance with the decision of the
Holy Synod of 16 March 1961, the head of the department should always be in the
episcopal dignity and a permanent member of the
Holy Synod of the Russian Orthodox Church. In the first half of 1962, the DECR purchased a building on , which became its headquarter for many years. From 1967) to 2009, the DECR of the MP published the
Information Bulletin of the Department for External Church Relations of the Moscow Patriarchate ().
1970s to 2009 On July 25, 1979, by the decision of the Holy Synod in
Leningrad, another branch of the DECR was established under the Metropolitan of Leningrad and Novgorod., with the building of the Department for External Church Relations of the Moscow Patriarchate behind (in

Moscow Danilov Monastery which had been the transferred to the Church on the eve of the anniversary of the 1000th anniversary of the
baptism of Rus'. On 21 August 1997, in connection with the restructuring of the department, "instead of the pre-existing sectors responsible for certain narrow areas of the Department's activities", new divisions appeared: the secretariat for inter-Eastern-Orthodox relations and foreign institutions, the secretariat for inter-Christian relations, the secretariat for relations between the Church and society and the administrative and financial secretariat; sectors for foreign institutions, Eastern Orthodox pilgrimage, and later the communication service and publication sector.
Since 2009 Patriarch Kirill's decentralisation On 31 March 2009, the
Holy Synod, at its first meeting under the chairmanship of the newly elected
Patriarch Kirill, reformed the DECR, forming new synodal institutions, which were entrusted with certain areas of activity previously dealt with by the DECR. The post-graduate department of the
Moscow Theological Academy, which operated under the DECR, was transformed into the . In 2011, on the occasion of its 65th anniversary, with funds allocated by the Saint Gregory the Theologian's Charity Foundation, the DECR facade was decorated with a
