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, as the last standing Kingdom, the Tsardom of Vidin, was conquered in 1396. As a result of the wars the Ottoman Empire greatly expanded its territory on the Balkan peninsula, stretching from Danube to the Aegean Sea.
