In Poland, the acute class contradictions of the period preceding the bourgeois revolution were intertwined with the contradictions generated by the national oppression and dismemberment of Poland. The restoration of national independence and the reunification of Polish lands became during this period, when the formation of the Polish bourgeois nation was intensively going on, important conditions for the progressive development of the Polish people. All this determined both the severity of the development of the social movement in Poland, and its complexity, its internal inconsistency. It was attended by representatives of the so-called "middle class" - the bourgeoisie and the bourgeois intelligentsia. At the end of this period, especially during the uprising of 1830-1831, a democratic trend is outlined in the social movement, expressing the interests of the urban lower classes and the peasantry.
