Throughout history, it feels as though the Anglo-sphere’s view of the lands surrounding the Baltic has been understandably shaped by the Viking cultures and the progenitors of the contemporary Swedish, Norwegian, Icelandic and Danish states.
Information on Finland, however, during this ancient and early-Medieval period before the Swedish crusades seems really sparse, and altogether lacking - at least in popular history.
What was Finland like during this broad period, and was it roughly analogous to the Vikings? Did they have a similar culture, did they practice raiding, etc. The Finnic pantheon seems similar to their Norse neighbours, was this due to cultural exchange? What were the events and customs that shaped life for them?
While more can always be said on the topic, I summarized some links to relevant answers by /u/platypuskeeper, also with a brief answer by myself, before in: What was life like in Finland some time before the Swedes arrived in the 1100s?

This specific topic indeed attracts more and more attention in recent scholarship: To give an example, an Estonian researcher Marika Mägi argues that some inhabitants of now Finland and Balts adapted the warrior way of the life of the Viking Age Scandinavians together with the weapon by trade, and shared the similar warrior culture around the (northern) Baltic (if you are interested in this aspect of the warrior culture based on the archaeology, check [Mägi 2019] in the linked post).
As for the impact and continuity of this Viking-like warrior culture among the Baltic peoples down to around 1200 CE, I also posted a answer before to: How active were baltic raiders prior to the Livonian and Teutonic orders arrival?.
