The Serbian Medieval State emerged in the 12th century, evolving from the Grand Principality of Serbia. It reached its peak during the reign of Stefan Dušan in the 14th century, when it expanded significantly and became a powerful empire in the Balkans. The state was characterized by a feudal system and a strong Orthodox Christian influence. The Serbian Orthodox Church played a crucial role in unifying the people and promoting literacy and culture. The state faced challenges from neighboring powers, including the Ottoman Empire, which eventually led to its decline in the late 15th century. Despite this, the legacy of the Serbian Medieval State remains significant in Serbian history.
