For our freedom and yours (Polish: Za naszą i waszą wolność) is one of the unofficial mottos of Poland. It is commonly associated with the times when Polish soldiers, exiled from the partitioned Poland, fought in various independence movements all over the world. First seen during a patriotic demonstration to commemorate the Decembrists, held in Warsaw on January 25, 18311, it was most probably authored by Joachim Lelewel. The initial banner has the inscription in both Polish and Russian, and was meant to underline that the victory of Decembrists would also have meant liberty for Poland. The slogan got shorter with time; the original had the form 'In the name of God, for our freedom and yours' ('W imię Boga za Naszą i Waszą Wolność'). The original banner has been preserved in the collection of Muzeum Wojska Polskiego in Warsaw.
One of the first prominent examples of Poles embodying the slogan and assisting other nations freedom struggles in addition to fighting for Polish causes were Tadeusz Kosciuszko and Kazimierz Pulaski who both fought on the American side in the American War of Independence (1775–1783). Kosciuszko later returned to Poland lead an insurrection against Russia and the partitioning of Poland among Russia, Prussia and Austria. Pulaski had already led an earlier Polish uprising against Russian influence in Poland and died in battle against British troops in Georgia in 1779. The slogan soon became very popular and became among the most commonly seen on military standards during the November Uprising (1830–1831). During the war against Russia, the slogan was to signify that the Polish victory would also mean liberty for the peoples of Russia and that the uprising was aimed not at the Russian nation but at the despotic tsarist regime. Following the failure of the uprising the slogan was used by a variety of Polish military units formed abroad out of refugees. Among them was the unit of Józef Bem, which featured the text in both Polish and Hungarian during the Hungarian Revolution of 1848 and wherever Poles fought during the Spring of Nations.
