The Battle of Velbazhd was fought by the Bulgarian Empire and the Kingdom of Serbia on 28 July 1330, near the town of Velbazhd (present day Kyustendil).
The growing power of the Serbian Kingdom from the late 13th century raised serious concerns in the traditional Balkan powers Bulgaria and Byzantine Empire which agreed for joint military actions against Serbia in 1327. Three years later the bulk of the Bulgarian and Serbian armies clashed at Velbazhd and the Bulgarians were caught by surprise. Serbian victory shaped the balance of power in Balkans for the next two decades. The Bulgarians did not lose territory after the battle but were unable to stop the Serbian advance towards Macedonia.
