The political struggle that began as "an issue of constitution" between Prince Milosh Obrenovich and the chiefs (staresina) in the Serbian Principality has become one of the most important international issues around 1835 in the Balkans. In this struggle, England gave support to a solution in which the Prince would not lose his power, while Russia and the Ottoman Empire insisted to establish an administration in which the power of prince should be limited by Soviet, a kind of Senate, in the principality. Finally, in accordance with the Russia's and the Ottoman Empire's demands, the kanunname, which is called Turski Ustav (Turkish Constitution) by the Serbs, was promulgated by Mahmud II in the December of 1838. This kanunname remained as the main judicial and administrative document of the Serbian Principality until 1869. In this article, the international dimension of this struggle, the policy of the Great Powers and the Ottoman Empire on this issue have been examined by using the Ottoman archival sources and the related literatures.
