The article aims at assessing the impact of extra taxes on the Swedish peasantry in the early 16th century in qualitative terms, as reflected in contemporary correspondence letters. While the total tax pressure without doubt rose in the period, the resilience of Swedish peasants was remarkably high. Despite harvest failures, they managed to endure the hardships, largely thanks to their diligent use of the instrument of negotiations over terms and levels of extra taxes and the delicacy with which the Crown exacted them. This can be seen as a reflection of adjustments within the framework of the prevalent medieval system, and an acceptance on both sides of the principle of mutuality.
