Broad linguistic and cultural grouping of Finno-Ugric-speaking peoples (ancestral to the Finns, Estonians, Karelians, and related Volga-Finnic groups) around the Baltic Sea and northwestern Russia, organized in scattered tribal societies rather than states in this period.
No single terminal event; gradually differentiates into the specifically-named medieval Finnic peoples (Suomi/Finns proper, Karelians, ancient Estonians), several of which are separately named in the historical-basemaps world_1000 snapshot ('Chuds', 'Karelians', 'Suomi').
Modern survey history of Finland that opens with the deep prehistoric and early Finnic-speaking background before the medieval and modern state.
