The Serbian Revolution starts.
The First Serbian Uprising was an uprising of Serbs in the Sanjak of Smederevo against the Ottoman Empire from 14 February 1804 to 7 October 1813. Initially a local revolt against renegade janissaries who had seized power through a coup, it evolved into a war for independence (the Serbian Revolution) after more than three centuries of Ottoman rule and short-lasting Austrian occupations.
The janissary commanders murdered the Ottoman Vizier in 1801 and occupied the sanjak, ruling it independently from the Sultan. Tyranny ensued; the janissaries suspended the rights granted to Serbs by the Sultan earlier, and increased taxes, and imposed forced labor, among other things. In 1804 the janissaries feared that the Sultan would use the Serbs against them, so they murdered many Serbian chiefs. Enraged, an assembly chose Kara?or?e as leader of the uprising, and the rebel army quickly defeated and took over towns throughout the sanjak, technically fighting for the Sultan. The Sultan, fearing their power, ordered all pashaliks in the region to crush them. The Serbs marched against the Ottomans and, after major victories in 1805–06, established a government and parliament that returned the land to the people, abolished forced labor and reduced taxes.
Military success continued over the years; however, there was dissent between Kara?or?e and other leaders—Kara?or?e wanted absolute power while his dukes, some of whom abused their privileges for personal gain, wanted to limit it. After the Russo-Turkish War ended and Russian support ceased, the Ottoman Empire exploited these circumstances and reconquered Serbia in 1813.Although the uprising was crushed, it was continued by the Second Serbian Uprising in 1815, which resulted in the creation of the Principality of Serbia, as it gained semi-independence from the Ottoman Empire in 1817.
