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

1530 - 1794

The Polish-Lithuanian Commonwealth (formalized by the Union of Lublin in 1569) reshaped the region's cultural landscape from the top down. The local nobility — powerful families like the Radvilas (Radziwiłłs), who owned Jašiūnai from the 15th century — adopted Polish language, Catholic piety, and the Commonwealth's political culture. This was not a simple imposition: the region's landowning class chose Polish identity as the language of prestige and statecraft, and their manors became outposts of Polish-language Catholic ritual. The Tabariškės Carmelite monastery, founded by Mykolas Vazinskis (Skarbek-Ważyński) in the 1770s, served as both a religious house and a Polish-language cultural institution — running a school, hospital, and shelter while maintaining devotions that transmitted Polish Catholic practice to the rural population. The Eišiškės parish school (documented from 1524) educated local youth in a Polish Catholic framework. The result was a layered community: noble manors and parish churches operating in Polish, while the surrounding peasantry spoke what would later be called prostaya mova (simple speech) and identified as tutejszy — 'people from here.' The festival calendar was already bilingual in practice, even if parish records recorded only the Polish liturgical layer.

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.
