Grand Principality of Serbia
Serbian Civil WarBosnia and Herzegovina
The new Pope Innocent III, who in a letter in 1198 called on the entire West to liberate the Holy Land, was not satisfied with the fact that the Serbs were subordinated to the Patriarch of Constantinople, but wanted to return them to Rome through Vukan.
In 1198, the Hungarian dux Andrew conquered Hum (Hercegovina) of grand zoupan Stefan and rebelled against brother king Emeric but did not gain legitimacy from Rome. In any case, the Hungarians became dominant on the eastern Adriatic coast. But Venice, because of its business interests, did not like the eastern coast of the Adriatic to be controlled by the mighty Byzantium or Hungary. Vukan and the Hungarian king Emeric (1196-1204) make an alliance against Stefan, after which a civil war breaks out in Serbia.
