The Obrenović Dynasty was a Serbian royal family that played a significant role in the modern history of Serbia. Founded in the early 19th century, the dynasty emerged during the Serbian Revolution against Ottoman rule. Key figures include Prince Miloš Obrenović, who established the dynasty's prominence, and his descendants who ruled Serbia intermittently until the early 20th century. The dynasty is known for its efforts to modernize Serbia, including reforms in administration, education, and military. However, it faced challenges, including rivalries with the Karađorđević Dynasty and internal conflicts. The Obrenović family ultimately lost power in 1903, leading to the establishment of a new royal line.
