What year did the northern crusades begin particularly in Finnmark,Norrbotten and Finland?

Question

I read once an edict from the Pope in 1020 began it for those in northern Sweden and Anund Jakob led an army in 1050 north, but is there proof this is when it started or was it a century later in Finland? Keep in mind,the northern crusades,not middle east.

Answer 1

Approximately 1154.
