 The crusade is only known from later legends that presented the expedition (if it ever took place) as a Christian mission, headed by a saint king to baptize heathens.However, it seems to have followed the exceptionally edgy 1140s with both the Yem and Swedes fighting against Novgorod.Some historians have seen it as a direct reaction to the failed Yem expedition in 1149, associating it with the co-operation mentioned by the Pope 20 years later.
