Most of the liberated lands, with the exception of the Lvov region, became incorporated into the Duchy through the peace treaty of 14 October 1809. Prince Józef himself, celebrated by the residents of the old royal capital of Poland, remained in Kraków until the end of December, supervising the provisional Galician government in existence from 2 June to 28 December. The Austrians kept demanding the return of Kraków and he felt that his presence there was the best assurance that the city would remain in Polish hands.
