Battle of Gvozd Mountain

The Battle of Gvozd Mountain took place in the year 1097 and was fought on Petrova Gora (Peter's Mountain) in central Croatia, between the army of Croatian king Petar Svačić and King Coloman I of Hungary. It was a decisive Hungarian victory and resulted in the death of Petar Svačić.

Battle
In an attempt to win the crown of the Kingdom of Croatia, the Hungarian army crossed the river Drava and invaded the Croatian territory, trying to reach the Adriatic coast. King Peter II of Croatia then moved from his residency at Knin castle in an attempt to defend his kingdom from the Hungarians. King Peter and his army moved north to meet advancing Hungarians, and the two armies met each other in the vicinity of Peter's Mountain. After a fierce battle, King Peter was killed.

Aftermath
The mountain where this bloody battle had taken place was later named Peter's Mountain in honour of the king who fell there. The outcome was disastrous for his army and country because this battle marked the end of the dynasty of Croatian national kings. The winner of the battle, King Coloman of Hungary created a personal union between the kingdoms of Croatia and Hungary. He was then crowned as King of Croatia in the Croatian capital Biograd on the Adriatic coast in 1102. Until the end of the World War I in 1918, the two crowns were united in personal union.
