The territory of what is now the Republic of Serbia was part of the Ottoman Empire throughout the Early Modern period. Ottoman culture significantly influenced the region, in architecture, cuisine, linguistics, and dress, especially in arts, and Islam.
In the 14th and 15th centuries, the Serbian Despotate was subdued by the Ottoman conquest of the Balkans. The Ottomans defeated the Serbs at the Battle of Maritsa in 1371, making vassals of the southern governors, soon thereafter, the Emperor died. As Uroš was childless and the nobility could not agree on the rightful heir, the Empire was ruled by semi-independent provincial lords, who often were in feuds with each other. The most powerful of these, Tsar Lazar, a Duke of present-day central Serbia (which had not yet come under Ottoman rule), stood against the Ottomans at the Battle of Kosovo in 1389. The result was indecisive, but it resulted in the subsequent fall of Serbia.Stefan Lazarević, the son of Lazar, succeeded as ruler, but had by 1394 become an Ottoman vassal. In 1402 he renounced Ottoman rule and became an Hungarian ally, the years following are characterized by the Ottomans and Hungary battling over the territory of Serbia. In 1453, the Ottomans conquered Constantinople, and in 1458 Athens was taken. In 1459, Serbia was annexed, Greece as well, a year later.
