In the winter of 1236–1237, there was a rebellion by dissatisfied Tavastians against Sweden at a time when the Catholic Church had not yet firmly established its presence in the region.[2] The rebels received assistance from the Novgorod Republic, which sought to diminish Swedish influence in Finland in order to bolster its own position.[2]

Pope Gregory IX described the event in a papal letter dated 9 December 1237 and addressed to Jarler, archbishop of Uppsala.[3]

He describes how the Tavastians returned to their pagan beliefs from Christianity and destroyed the Catholic church in Häme. He goes into detail describing other atrocities committed by the Tavastians.[3] This has been seen as papal propaganda.[4] Finally, he issued a call for a crusade against the rebels.[2][3] Ultimately, harsh measures were employed to quell the uprising.[2]

In 1237, Russia experienced its first Mongol invasion. Although the Mongol incursion did not directly threaten northwestern Russia and Novgorod, the fear of raids still loomed over Novgorod, leading to a decrease in activity in Finland.[2]
