Bulgarian–Ottoman wars

The Bulgarian–Ottoman wars were fought between the kingdoms remaining from the disintegrating Second Bulgarian Empire, and the Ottoman Empire, in the second half of the 14th century. The wars resulted with the collapse and subordination of the Bulgarian Empire, and effectively came to an end with the Ottoman conquest of Tarnovo in July 1393, although other Bulgarian states held out slightly longer, such as the Tsardom of Vidin until 1396 and the Despotate of Dobruja until 1411. As a result of the wars the Ottoman Empire greatly expanded its territory on the Balkan peninsula, stretching from the Danube to the Aegean Sea.
