The Serbian Revolution begins.

The Serbian Revolution (Serbian: Српска револуција / Srpska revolucija) was a national uprising and constitutional change in Serbia that took place between 1804 and 1835, during which this territory evolved from an Ottoman province into a rebel territory, a constitutional monarchy, and modern Serbia. The first part of the period, from 1804 to 1817, was marked by a violent struggle for independence from the Ottoman Empire with two armed uprisings taking place, ending with a ceasefire. The later period (1817–1835) witnessed a peaceful consolidation of political power of the increasingly autonomous Serbia, culminating in the recognition of the right to hereditary rule by Serbian princes in 1830 and 1833 and the territorial expansion of the young monarchy. The adoption of the first written Constitution in 1835 abolished feudalism and serfdom, and made the country suzerain. The term Serbian Revolution was coined by a German academic historiographer, Leopold von Ranke, in his book Die Serbische Revolution, published in 1829. These events marked the foundation of modern Serbia.The period is further divided as follows:

First Serbian Uprising (1804–13), led by Karađorđe Petrović

Hadži-Prodan's rebellion (1814)

Second Serbian Uprising (1815–17), led by Miloš Obrenović

Official recognition of the Serbian state (1815–1833)The Proclamation (1809) by Karađorđe in the capital Belgrade probably represented the apex of the first phase. It called for national unity, drawing on Serbian history to demand the freedom of religion and formal, written rule of law, both of which the Ottoman Empire had failed to provide. It also called on Serbs to stop paying taxes to the Porte, deemed unfair as based on religious affiliation. Apart from dispensing with poll tax on non-Muslims (jizya), the revolutionaries also abolished all feudal obligations in 1806, only 15 years after the French revolution, peasant and serf emancipation thus representing a major social break with the past. The rule of Miloš Obrenović consolidated the achievements of the Uprisings, leading to the proclamation of the first constitution in the Balkans and the establishment of the first Serbian institution of higher learning still in existence, the Great Academy of Belgrade (1808). In 1830 and again in 1833, Serbia was recognized as an autonomous principality, with hereditary princes paying annual tribute to the Porte. Finally, de facto independence came in 1867, with the withdrawal of Ottoman garrisons from the principality; de jure independence was formally recognized at the Congress of Berlin in 1878.
