The Principality of Serbia was a semi-independent state in the Balkans that came into existence as a result of the Serbian Revolution which lasted between 1804 and 1817. Its creation was negotiated first through an unwritten agreement between Miloš Obrenovic, leader of the Second Serbian Uprising and Ottoman official Marashli Pasha. It was followed by the series of legal documents published by the Porte in 1828, 1829 and finally, 1830 — the Hatt-i Sharif.
