Ladislaus I of Hungary
After the death of Croatian King Stephen II in 1091, a period of succession crisis followed in Croatia, with King Ladislaus I of Hungary interfering in it. Byzantine Emperor Alexius took advantage of this and joined the old Theme of Dalmatia to the Empire. In 1096 Emperor Alexius, at the time engaged in the First Crusade, granted the administration of Dalmatia to the Doge of Venice.
