Marxist scholars (e.g., Aleksandr Khoroshev) often spoke of class struggle in Novgorod. There were some 80 major uprisings in the republic, which often turned into armed rebellions. The most notable among these took place in 1136, 1207, 1228–29, 1270, 1418, and 1446–47. The extent to which these were based on "class struggle" is unclear. Many were between various boyar factions or, if a revolt did involve the peasants or tradesmen against the boyars, it did not consist of the peasants wanting to overthrow the existing social order, but was more often than not a demand for better rule on the part of the ruling class. There did not seem to be a sense that the office of prince should be abolished or that the peasants should be allowed to run the city.
