1617 - 1721

Sweden's expansion after the 1617 Treaty of Stolbova brought the entire Karelian isthmus and Ladoga Karelia under Swedish control, creating two simultaneous and opposite population movements. Savonian Lutheran settlers practising slash-and-burn agriculture (kaskiviljely) expanded from their heartland into the forest interior of Kainuu, North Savo, and South Savo, clearing new land and establishing a Lutheran agricultural landscape. Meanwhile, Orthodox Karelians — unwilling to convert to Lutheranism — migrated eastward, many settling in the Tver region of Russia, creating the Tver Karelian diaspora that still maintains a Karelian-language tradition today. Olavinlinna Castle, built in 1475 at Savonlinna to guard the Swedish-Muscovite frontier, was besieged multiple times and captured by Russia in 1714. Kajaani Castle, constructed starting in 1604 on the Kajaani River, served as Sweden's administrative center for the northern frontier until its destruction by Russian forces in 1716. The dual narrative of Lutheran settlement and Orthodox displacement is essential: the same era that created the Savonian agricultural heritage also displaced the Orthodox Karelian communities whose liturgical tradition had structured the region's festival life.

1809 - 1917

Finland's autonomy as a Grand Duchy within the Russian Empire (1809–1917) created the conditions for a Finnish national awakening that would profoundly reshape how Eastern Finland's cultural heritage was understood and used. The Saimaa Canal (built 1845–1856) connected Lappeenranta to Vyborg and the Gulf of Finland, integrating the lakeland into imperial trade networks. Elias Lönnrot's poetry-collecting expeditions to White Karelia (now Russia) produced the Kalevala (Old Kalevala 1835, New Kalevala 1849) — an editorial construction that combined, reordered, and modified material from multiple rune singers across different regions and periods. The Karelianism movement that followed projected a Finnish-national reading onto Karelian Orthodox and Slavic-influenced traditions, framing Karelia as preserving 'Finnishness in its purest state' — a frame that risks erasing the distinctiveness of Karelian Orthodox practice. The Church of Saint Elijah in Ilomantsi was completed in 1891 on the site of a late 15th-century orthodox temple, and the Joensuu Orthodox Parish's St. Nicholas Church was consecrated in 1887. At Koli, national-romantic painters like Eero Järnefelt and composers like Jean Sibelius discovered a landscape they would transform into an icon of Finnish identity — a reading that overlaid Savonian agricultural heritage (kaskiviljely) with a national-aesthetic narrative.

1323 - 1617

The 1323 Treaty of Nöteborg (Teusina) sundered Karelian lands and their inhabitants: western Karelia fell under Swedish sovereignty (eventually becoming Roman Catholic and then Lutheran), while eastern Karelia fell under Novgorodian rule (remaining Eastern Orthodox). This partition created a confessional frontier that still shapes the cultural geography of Eastern Finland. The Swedish crown built Vyborg Castle (1293) and Kexholm Castle (1295) as instruments of territorial control, while the Orthodox Karelian communities on the Swedish side lived under a Catholic and later Lutheran authority that pressed them toward conversion. By the late 15th century, an orthodox temple stood in Ilomantsi — the farthest Orthodox outpost on the Swedish side of the border. The confessional divide meant that two different festival-structuring systems — Lutheran agricultural calendars and Orthodox liturgical calendars — would coexist and sometimes conflict across the same lakeland landscape.

1917 - 1945

Finland's independence in 1917 and the wars that followed (Winter War 1939–1940, Continuation War 1941–1944) violently reshaped the borderland. The Orthodox Church of Finland separated from the Russian patriarchate in 1923, joining the Ecumenical Patriarchate of Constantinople and adopting the Gregorian calendar — a shift that moved fixed feast-day dates by up to 13 days and replaced Church Slavonic with Finnish liturgy, creating a significant transformation in the praasniekka tradition even as its structural continuity was preserved. The evacuation of Valaam Monastery and Lintula Convent from Ladoga Karelia to Heinävesi in 1940 transplanted entire Orthodox institutions — with their liturgical calendars, icon traditions, and monastic communities — into a new landscape. The Ilomantsi Battlegrounds Trail marks the only Finnish municipality that saw major division-level battles in both the Winter and Continuation Wars, with approximately 50,000 men engaged. The post-war settlement ceded Ladoga Karelia to the Soviet Union, displacing over 400,000 Finnish citizens — including the entire Orthodox parish infrastructure of the ceded territories. The Orthodox Karelian communities in present-day Eastern Finland (especially Ilomantsi, with its 17.4% Orthodox population — the highest in any Finnish municipality) maintained their praasniekka practice through the upheaval, but the evacuee narrative came to dominate Finnish memory politics, often reducing Karelian culture to nostalgia for a lost homeland rather than recognizing it as a living tradition.
