The Bulgarian–Hungarian wars are a series of conflicts that take place between the Bulgarian Empire and the Kingdom of Hungary between the 9th and 14th centuries.
The areas of the conflict encompass the northern and western Balkans, more specifically modern northwestern Serbia, Romania and northern Bulgaria.During the first clashes in the late 9th century, the Hungarians are forced to migrate to the west.
During the Hungarian conquest in the 10th century the Magyars overrun the Bulgarian dukes of what is now Transylvania and eliminate the Bulgarian rule in the eastern parts of the Pannonian plain.
Their plunder raids against Bulgaria continue until the end of the first end of the century when peace is concluded.
Both countries sustain friendly relations until 1003 when another war breaks out.After the reestablishment of the Bulgarian Empire in 1185 both states fight numerous conflicts for control over the provinces of Belgrade, Branicevo, Vidin and Severin Banat.
