| PER_FINN_TRADITIONAL | Finnish | Finnish Traditional / Pre-Christian | -500 | 1300 | Period of Finnish and Karelian pre-Christian religious practice, from the emergence of the Baltic Finnic culture group (c. 500 BCE) through the completion of formal Christianization (12th–14th centuries CE; Bishop Henry's crusade in Finland c. 1155 CE; full Christianization of Karelia by c. 1300 CE). The religious traditions documented in the Kalevala oral poetry represent this period, though the surviving written attestation comes later: Mikael Agricola's 1551 deity list is the earliest written primary source, and Elias Lönnrot's 1835/1849 Kalevala compilations are the main documentary corpus. The oral runo-song tradition preserved in the Kalevala is estimated to reflect religious practices from the Iron Age through early medieval Finnish/Karelian culture. Pentikäinen (1999) is the standard scholarly reference for this period's religious content. |
