Đorđe Petrović OSA, known as Karađorđe, founded modern Serbia as the elected leader of the First Serbian Uprising that aimed at liberating Serbia from the Ottoman Empire; he personally led armies against the Ottomans in several battles, which resulted in a short-lived state which he would administer as Grand Leader from 14 February 1804 to 21 September 1813, alongside the newly founded People's Assembly and the Governing Council, simulating a wholly functional state government in war-time. Born into a poor family in Šumadija, at the time part of the Sanjak of Smederevo, Đorđe began working as a servant for affluent Serbs and Turks, but after having killed a local Ottoman aga, his family fled across the Sava into the Military Frontier, a Habsburg-controlled area. He rose to prominence in the Austrian army, participating in Koča's frontier rebellion. He received a medal of honour for his efforts, and when the Austrian army was forced to retreat, and the Ottomans re-occupied Šumadija, he joined the hajduks. He commanded a unit and fought the Ottomans until 1794, when he returned to his family.
