How Catholic Was the Grand Duchy of Lithuania in the Later Eighteenth Century?

Abstract

In 1784 King Stanisław August Poniatowski undertook a splendid progress across the south-western parts of the Grand Duchy of Lithuania. The official account of the journey prompts the reflection that even in this linguistically and confessionally mixed part of the Polish-Lithuanian Commonwealth, the precedence over other confessions of the Catholic Church of both rites, Latin and Ruthenian, was axiomatic. By the mid-eighteenth century, about five-sixths of the Commonwealth’s population, the vast majority of the noble citizenry, and the entire legislature were Catholic. However, Catholics of the Latin rite constituted only about half of the population. Most Catholics of the Ruthenian rite (Uniates) were in only nominal obedience to Rome; they were the object of a struggle for the allegiance and salvation of souls, conducted between an advancing Catholic Church and a retreating Orthodox Church. The fault line between Eastern and Western Christendom ran through both the Polish Crown and the Grand Duchy of Lithuania; Orthodoxy retained strongholds in both parts of the Commonwealth. However, the position of the ‘Latin’ Church was, in most ways, significantly weaker in the Grand Duchy, where the majority of the inhabitants were Uniates. Adapting recent mutations in ‘confessionalization theory’, this paper first reviews the confessional balance, and the privileges, structures, educational institutions, and missionary work of the Catholic Church (of both rites) in the Grand Duchy of Lithuania in the second half of the eighteenth century. It then asks how the dramatic events of Stanisław August’s reign (1764–95) affected Catholic supremacy. These changes included the enforced removal of the Catholic monopoly of the legislature in 1768, the impact of the first partition of the Commonwealth in 1772, the Orthodox revivals under Bishops Georgii Konisskii and Viktor Sadkovskii, as well as the formulation of new policies intended to promote loyalty to the Commonwealth and social cohesion during the Four Years’ Sejm (1788–92). It concludes that the partial ‘deconfessionalization’ of the polity had (or might have had) a proportionately greater impact on the Grand Duchy of Lithuania than on the Polish Crown.
