The Roman Catholic Diocese of Minsk was a territorial unit of the Latin Church, with its seat in the city of Minsk. It was established by imperial ukase on 28 April 1798, and approved by the Apostolic See by decree on 29 July 1798. It was abolished by imperial ukase in 1869.
The Diocese of Minsk was established in the territories of present-day Belarus, which in the 19th century belonged to the Russian Empire as part of the Russian Partition. Its boundaries were delineated by a triangle, with the northern (upper) vertex being the mouth of the river into the Daugava, and the base being a line to the south of the Pripyat river. It encompassed the area of the Minsk Governorate and bordered the dioceses of Vilnius, Lutsk, Zhytomyr, and Mogilev. Ecclesiastically, the Minsk diocese was part of the Mogilev ecclesiastical province. Its area at the beginning of its existence was over 90,000 km2.
The period after the January Uprising was the decline of the diocese. It was abolished in 1869. The areas under its care were re-incorporated into the Vilnius diocese but later, after 1882, the territory was governed as apostolic administrator by the Archbishop of Mohilev.
The diocese of Minsk was revived as an independent see in 1917 (Zygmunt Łoziński was the Bishop of Minsk until 1925) but it was vacant between 1925 and 1991 when it merged with Mohilev to form the current Archdiocese of Minsk-Mohilev.
Catholics in the Russian Empire in the second half of the 18th century
Catholics in Russia before the First Partition of Poland
In the middle of the 18th century, there were about 10,000 Latin Catholics living in the Orthodox Russian Empire. They were exclusively foreigners – Germans, French, Italians, and Poles. They gathered around churches in Moscow and St. Petersburg, as well as in the colonies of foreign evoys, workers, factories, and merchants.
Catholic mission stations operating in various parts of the Russian Empire were subject to the Sacred Congregation for the Propagation of the Faith. By the decree of Catherine the Great on 6 November 1766, Catholic missions and communities were subordinated to the Inflanck-Estonian-Finnish Justiz College. On 12 February 1769, the empress signed the Dannyj Sanktpetersburgsoj Rimsko-Katoličeskoj Cerkvi regulation, specifying the conditions for the activities of Catholic communities in Russia.
As a result of the First Partition of Poland in 1772, Russia expanded its territory by about 92,000 km2, inhabited by about 1.3 million people, including about 100,000 Roman Catholics and about 800,000 Greek Catholics. In terms of the administrative structures of the Roman Catholic Church, Russia received the Diocese of Smolensk and parts of the dioceses of Vilnius and Inflanty belonging to the province of the Archdiocese of Gniezno.
Catherine the Great's policy toward Catholics As a result of the First Partition of Poland in 1772, Russia acquired eastern territories with a significant Catholic population. This posed a challenge for organizing the Catholic Church. Anticipating demands from the Roman Curia and having a negative attitude towards the papacy, Catherine the Great decided to address this issue independently. Not recognizing the papal authority over the Catholic Church in the Russian Empire and desiring to eliminate any external influence over it in Russia, Catherine the Great established, by decree on 22 November 1773, the Belarusian Diocese with its seat in Mogilev on the Dnieper river. She appointed Stanisław Bohusz Siestrzeńcewicz, a suffragan bishop of Vilnius, who was to implement her policies towards the Catholic Church and its followers. On the empress' orders, the bishop, among other things, did not announce the papal brief of Clement XIV on the suppression of the Jesuits, as Catherine the Great believed that the order would positively contribute to the development of education in Russia. With authority over the orders in Russia, Siestrzeńcewicz opened a novitiate for the Jesuits in Polotsk. The Belarusian Diocese did not receive canonical approval from the Apostolic See because it was established in violation of canon law principles.
In the 1770s, Catherine the Great introduced restrictions on the contacts of the Catholic clergy in Russia with the Apostolic See, subjected the monastic clergy to the Belarusian bishop, and prohibited the Metropolitan of the Ruthenian Uniate Church, who remained in the Commonwealth, from assuming jurisdiction over the Saint Sophia Cathedral in Polotsk. There was a real threat to the Greek Catholic faithful, as there were discussions in St. Petersburg about appointing an Orthodox bishop to the Uniate diocese. The decree of 13 July 1780 defined Catherine the Great's policy towards the Greek Catholic Church in Russia, condemning it to gradual absorption by the Orthodox Church. As a result of such activities, the Pope, fearing the abolition of the Union and the loss of about 1.2 million faithful, was forced to seek ways of agreement with Catherine the Great. Diplomatic relations between Russia and the Apostolic See were established after 17 January 1782, when the empress unilaterally established the archbishopric of Mogilev headed by Siestrzeńcewicz. The Mogilev archdiocese encompassed the entire Russia, without suffragan dioceses. This issue was to be resolved in the future. The metropolitan's endowment was a government salary of 10,000 silver rubles. To put an end to the uncertain situation in relations between Russia and the Apostolic See, the empress demanded the Pope's approval of the new archbishopric. After more than a year of negotiations, the Pope finally legitimized the archbishopric of Mogilev with the papal brief Onerosa pastoralis officii dated 15 April 1783. In 1784 the Empress appointed Heraclius Lisovsky as Uniate Archbishop of the Archeparchy of Polotsk-Vitebsk.
Second and Third Partitions of Poland and their consequences
As a result of the Second and Third Partitions of Poland, Russia absorbed approximately 370,000 km2 of territory inhabited by about 5.6 million people, including approximately 2 million Roman Catholics and about 800,000 Greek Catholics. In terms of the administrative division of Roman Catholic dioceses in the Polish–Lithuanian Commonwealth, as a result of the Second and Third Partitions, the Russian Empire annexed from the Lviv ecclesiastical province the Kyiv, Kamianets-Podilskyi, and the larger part of the Lutsk dioceses, which was fragmented by the borders of all three partitioning powers. From the Archdiocese of Gniezno, the remaining part of the Inflanty diocese, almost the entire Vilnius and Samogitia dioceses, fell within the borders of Russia.
After the annexation to Russia in 1793 and 1795 of parts of the Vilnius, Samogitia, Kamianets-Podilskyi, Lutsk dioceses, as well as the entire Inflanty and Kyiv dioceses, it was necessary to reorganize the existing territorial structures of the Catholic Church in the Russian Empire. This matter became very urgent because all the partitioning powers prohibited bishops from exercising jurisdiction beyond the borders of their state. After the occupation of the Grand Duchy of Lithuania, in accordance with the prevailing practice, a homage delegation representing all social groups, including the clergy of Vilnius, was sent to St. Petersburg to pay homage and present the society's demands. As part of this delegation, the Inflanty bishop suggested to the government the idea of expanding the Inflanty diocese at the expense of the extensive Vilnius diocese.The homage delegation of the clergy of Vilnius to St. Petersburg is considered by as the beginning of J. N. Kossakowski's career. Catherine the Great acted differently than Kossakowski anticipated, but nevertheless, Kossakowski was appointed by her as the bishop of Inflanty. The Inflanty bishopric with its seat in Vilnius was established as a result of the abolition of the Vilnius bishopric. Temporarily, the ecclesiastical matters in the territories annexed to Russia as a result of the Second and Third Partitions of Poland were regulated by the decree of Catherine the Great on 6 September 1795, which abolished the Vilnius, Lutsk, Kamianets-Podilsky, and Kyiv dioceses. The non-canonical Inflanty, Pinsk, and Letychiv dioceses were established, with the bishopric in Vilnius (headed by J. N. Kossakowski), Pinsk, and Letychiv. The Samogitia diocese continued to function unchanged. Kossakowski, however, went to Grodno, where all administrative matters of the country were concentrated. With the permission of Governor Nikolai Repnin and Catherine the Great, the bishop applied to the Pope for recognition of the September acts, but without success.
Population and religions of Minsk in the 19th century In terms of religious affiliation, at the turn of the 18th and 19th centuries, the area of the Minsk diocese was inhabited by Catholics of two rites: Latin (mainly Poles) and Uniate (Belarusians). The latter, constituting the decisive majority of the population in this area before the partitions of Poland, during Catherine the Great's policy of destroying the Union, under strong pressure from the authorities and the Orthodox clergy, were incorporated into the church prevailing in Russia. Since then, Orthodoxy has again become the dominant religion in these areas. This is evidenced by the establishment of the Orthodox Diocese of Minsk. A significant number of Jews adhering to Judaism were present, both in towns and in the countryside. In the second half of the 19th century, especially after the January Uprising, the Roman Catholic community in Belarus was greatly reduced. As a result, the Latin Catholics, who in the first half of the 19th century ranked second among the denominations in the Minsk Governorate, found themselves in the third place in the second half of the century, after the adherents of Orthodoxy and the Jewish religion. In the 1860s, the Catholic population in the Minsk diocese was just over 200,000. Experiencing losses in the following decades, by around 1900, they constituted only 3% of the population of the Minsk Governorate.
Reorganization of the structure of the Latin Church of Poland in the Russian Empire
After the death of Catherine the Great and the ascension of Tsar Paul I to the throne of the Russian Empire, there was a final and lasting organization of the structures of the Catholic Church. Paul I's attitude toward Catholics and the papacy differed from the policy pursued by his mother, Catherine the Great, but in priority matters, the new tsar did not deviate from the previous assumptions of the empress' church policy. The church in Russia was to continue functioning without being subject to any external influences. Due to the general international situation (Napoleon's occupation of the Papal States), the Roman Curia was inclined to make concessions regarding the Catholic Church in Russia.
