Listy Piotra Hiacynta Śliwickiego do nuncjusza Alberica Archinto z lat 1754–1757 w zbiorach Archiwum Watykańskiego

The article presents the hitherto unknown correspondence of the inspector of the general assembly of missionaries Piotr Hiacynt (Jacek) Śliwicki to the papal nuncio in the Polish-Lithuanian Commonwealth – Alberic Archinto, which is now preserved in the Vatican Archive. It includes three letters – two letters of 1754 and one of 1757, which are the evidence of the cooperation between the Church dignitaries. In the first letter Śliwicki referred to the conflict concerning the tithe, which lasted in the Polish-Lithuanian Commonwealth in the years 1752–1753. In both letters of 1754 he described to the papal nuncio the situation at the court of the bishop of Poznań Teodor Kazimierz Czartoryski, who was surrounded by Lutherans. In the letter of 1757 Śliwicki characterized the situation of Lazarists in Krasław, requesting some support (including financial help) from the Pope. The article was complemented by the source edition of the above-mentioned correspondence in the original language – French.
