In the 1389 Battle of Kosovo, they catastrophically defeated the Serbs:
The Greeks
The Albanians
The Turks
The Slavs
The Kosovars
The Turks. In the 1389 Battle of Kosovo, the Turks catastrophically defeated the Serbs. In the battle, the Serb prince Lazar was captured by the Turks and beheaded. The Battle of Kosovo, in which the Serbs chose death rather than surrender, remains a permanent symbol in the Serbian national consciousness. In 1459 the Serbs fell under Turkish rule and all of Serbia became the property of the sultan and all Serbs became bond-slaves to the land. Serbian national identity survived with the restoration in 1557 of the Serbian partiarchate at Pec.
