National Day in Serbia is observed on February 15 every year, commemorating the First Serbian Uprising in 1804 and the adoption of the first Serbian Constitution in 1835. The First Serbian Uprising aimed to gain independence from over three centuries of Ottoman rule and, despite its failure, set the stage for the successful Second Serbian Uprising two years later. The adoption of the constitution, known as the Candlemas constitution, occurred under Prince Miloš Obrenović I and is significant in Serbian history, even though it was canceled shortly after its adoption. This public holiday is marked by various celebrations and events that honor Serbia's struggle for autonomy and the establishment of its legal framework.
