The Second Serbian Uprising (1815-1817) was a second phase of the Serbian revolution against the Ottoman Empire, which erupted shortly after the re-annexation of the country to the Ottoman Empire, in 1813. The occupation was enforced following the defeat of the First Serbian Uprising (1804-1813), during which Serbia existed as a de facto independent state for over a decade. The second revolution ultimately resulted in Serbian semi-independence from the Ottoman Empire. The Principality of Serbia was established, governed by its own parliament, constitution and royal dynasty. De jure independence followed during the second half of the 19th century.
