After the fall of Napoleon, he met with Russia's Tsar Alexander I, in Paris and then in Braunau, Switzerland. The Tsar hoped that Kościuszko could be convinced to return to Poland, where the Tsar planned to create a new, Russian-allied Polish state (the Congress Kingdom). In return for his prospective services, Kościuszko demanded social reforms and restoration of territory, which he wished would reach the Dvina and Dnieper Rivers in the east. However, soon afterwards, in Vienna, Kościuszko learned that the Kingdom of Poland to be created by the Tsar would be even smaller than the earlier Duchy of Warsaw. Kościuszko called such an entity "a joke".
