The main plot of the film "The Principality of Serbia" was put in the first seven decades of the nineteenth century when the state was being formed and strengthened together with its historical fate. This film shows the Serbs as people who fought during the two Risings while trying to liberate by themselves hardly and for a long time. It also shows how they hardly got the recognition to their liberty and the international recognition to the right to have their own state.
