Polish-Lithuanian Commonwealth & Catholic Polonization

The Jagiellonian commonwealth, its multi-confessional frontier and the Partitions.

1385 - 1529

The Jagiellonian dynasty's conversion of Lithuania to Christianity in 1387 planted the parish network that still organizes festival life in this region today. Jogaila (Władysław Jagiełło) founded one of Lithuania's first churches at Nemenčinė in 1387, and Grand Duke Vytautas built a church at Eišiškės around 1398. Over the next century, parishes appeared at Dieveniškės (mentioned 1471), Rudamina (by 1500), and Turgeliai (first church 1500). These were not just houses of worship — they were the grid on which the entire ritual calendar of the region was laid out: baptism, marriage, burial, patronal feasts, and the agricultural liturgical year all ran through the parish. The language of these earliest services was likely Old Church Slavonic, Latin, or Ruthenian rather than Polish or Lithuanian as we know them; the Polish-language character of parish life developed later. But the parish boundaries Jogaila and Vytautas drew are, in many cases, the same ones that still govern where Corpus Christi processions walk and where pamaldos lenkų kalba (services in Polish) are held today.

1795 - 1863

After the Commonwealth's partition in 1795, the region fell under the Russian Empire — but the Polish-speaking nobility remained the local power brokers. Ignacy Baliński purchased Jašiūnai Manor from the Radvilas in 1811 and built a neoclassical residence (1824–1828) that became the region's most brilliant cultural salon. Adam Mickiewicz, the poet associated with Polish, Lithuanian, and Belarusian literary traditions, was a frequent guest — in 1821 he watched Vėlinės (All Souls' Day) rituals at the Šalčininkai cemetery, an experience that later surfaced in his poetry. Jan Śniadecki and Juliusz Słowacki also visited. The manor's library and ceramics workshop spread Polish-language culture through the district. Meanwhile, the Tabariškės Carmelites continued maintaining Polish devotions, and parish churches kept their liturgical calendars intact. The rural population — many still speaking prostaya mova and identifying as tutejszy — participated in Catholic feasts whose language was Polish but whose folk elements carried older, unrecorded local layers. The estate system meant that festival life was shaped by two parallel institutions: the noble manor's cultural patronage and the parish's liturgical authority.

1864 - 1918

The January Uprising of 1863 triggered the Russian Empire's most aggressive assault on Catholic and Polish identity in the Vilnius region. Churches were forcibly converted to Orthodox worship: Rudamina's predecessor church was consecrated as an Orthodox church of the Transfiguration in 1866, after 603 Catholics were registered as Orthodox. A new brick Orthodox church was built there in 1876. The Tabariškės Carmelite monastery had already been closed in 1832, but the parish church survived — and it is in this period that the parish became the sole institutional vessel for Polish-language continuity. When Polish schools were banned and public use of Polish restricted, the church remained the only place where the community could hear and speak Polish in a liturgical setting. After the 1905 Edict of Toleration, Catholic communities could build new churches: the current wooden church at Rudamina was constructed between 1907 and 1909, replacing the lost one. Dieveniškės saw Lithuanian-language sermons introduced from 1886 and 1897–1898, revealing that the parish's linguistic identity was not monolithic — the same community could hear both Polish and Lithuanian from the pulpit. The Jašiūnai Manor, after Baliński's death and the 1863 suppression, lost its position as a cultural centre; its valuable library was transported to Poland or lost during the wars. The festival calendar survived — but it was now carried exclusively by the parish, without the parallel patronage of the noble estate.

1919 - 1939

For two decades between the wars, this region was part of Poland's Wilno Voivodeship — a period that consolidated Polish-language institutions and Catholic parish life but also saw the coexistence of Jewish and Catholic calendars in the same market towns. The 1931 census recorded 59.7% Polish, 22.7% Belarusian, 8.5% Jewish, and 5.2% Lithuanian in the voivodeship. In Eišiškės, Jews constituted 28.84% of the population (687 people) by 1921, though their share had declined from a peak of 80% in 1820; the town maintained separate Polish and Lithuanian high schools. The market square in Eišiškės operated on a rhythm shaped by both the Catholic liturgical calendar and the Jewish commercial calendar — Shabbat, market days, and High Holidays structured the week alongside Sunday Mass and patronal feasts. Dieveniškės was 75% Jewish in the 1897 census and still had a significant Jewish community with two synagogues. Nemenčinė's parish school (founded 1777) continued under Polish administration. The parish churches — now operating freely in Polish — celebrated Corpus Christi processions, May devotions, and patronal feasts as public, visible expressions of community identity. But the tutejszy population still spoke prostaya mova at home, and the gap between standard Polish liturgical language and local vernacular remained. This was the last era before the destruction of the Jewish communities and the Soviet suppression of public Catholic practice erased two of the three calendars that had structured town life.
