Romas katoḷu Baznīcas Mariāṇu kongregācijas Latvijas kopienas izmaiṇas personāla sastāvā pēc oficiāliem kongregācijas datiem: 1926-1939

ENOne of the most important sources of research in the history of the Roman Catholic Church is the official statistics that helps to deduce the dynamics of changes in institutions. In the framework of this paper, there will be presented the origin, publication, and accessibility of the statistics about Congregation of Marian Fathers, as well as quantitative analysis of the personnel structure of Latvian Congregation community from the first official publication of statistics data in Official Congregationís annual "Elenchus" from 1926 till from 1939, when the last time before World War II the leadership of the Marian Congregation refused from publication of the statistics data. An analysis of data in the publication of official statistics provides an insight into the dynamics of monastic community development. The Marian Community of Latvia at the beginning of its existence in 1924, had only two priests, in 1926, when the first statistics was published, the community consisted of 13 persons, but in 1939 according to last published data before the war, in Latvia there were 45 Marians, and among them were 7 priests. Detailed analysis reveals that dynamics of the personnel structure was not equable and approximately half of those, who acceded into Congregation, later withdrew from it, however, the number of priests remained relatively stable, although there is noticed a growing dynamics. The official statistics can provide the researcher with basic data, which can be used as a basis for profound investigation of Marian activity in Latvia. Key words: Congregation of Marian Fathers, Roman Catholic Church in Latvia, monastic life, statistics, personnel structure.
