Biograd na Moru (pronounced [bîoɡraːd na mǒːru]), shortened to simply Biograd, is a town in northern Dalmatia in Croatia. It is significant for being another capital of the medieval Kingdom of Croatia. Biograd is administratively part of the Zadar County. It is located on the Adriatic Sea coast, overlooking the island of Pašman, on the road from Zadar and Sukošan towards Vodice and Šibenik.
The Kingdom of Croatia (Croatian: Kraljevina Hrvatska, Hrvatsko Kraljevstvo; Hungarian: Horvát királyság; Latin: Regnum Croatiae), also known with full diplomatic name Kingdom of Croatia and Dalmatia (Latin: Regnum Croatiae et Dalmatiae), entered a personal union with the Kingdom of Hungary in 1102, after a period of rule of kings from the Trpimirović and Svetoslavić dynasties and a succession crisis following the death of king Demetrius Zvonimir.
With the coronation of King Coloman of Hungary as "King of Croatia and Dalmatia" in 1102 in Biograd, the realm passed to the Árpád dynasty until 1301, when the (male) line of the dynasty died out. Then, kings from the Capetian House of Anjou, who were also cognatic descendants of the Árpád kings, ruled the kingdoms. Later centuries were characterized by conflicts with the Mongols, who sacked Zagreb in 1242, competition with Venice for control over Dalmatian coastal cities, and internal warfare among Croatian nobility. Various individuals emerged during the period, such as Paul I Šubić of Bribir, who was representing the most powerful Croatian dynasty at the time, the Šubić noble family. These powerful individuals were on occasion able to de facto secure great deal of independence for their fiefdoms. The Ottoman incursion into Europe in the 16th century significantly reduced Croatian territories and left the country weak and divided. After the death of Louis II in 1526 during the Battle of Mohács and a brief period of dynastic dispute, both crowns passed to the Austrian House of Habsburg, and the realms became part of the Habsburg monarchy.
The Klis Fortress (Croatian: Tvrđava Klis; Italian: Fortezza di Clissa) is a medieval fortress situated above the village of Klis, near Split, Croatia. From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, to a role as royal castle and seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times throughout its 2,000-year history. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman Empire. It has been a crossroad between the Mediterranean Sea and the Balkans.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia's rulers. His successor, Duke Trpimir I, is significant for spreading Christianity in the Duchy of Croatia. He expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
Peter Krešimir IV (Croatian: Petar Krešimir IV.) was King of Croatia and Dalmatia from 1059 until his death in 1074. He was the last ruler of the Krešimirović branch of the Trpimirović dynasty.
Under Peter Krešimir IV, the Croatian realm reached its peak territorially. He kept his seat at Nin and Biograd na Moru; however, the city of Šibenik holds a statue of him and is sometimes called "Krešimir's city" (Croatian: "Krešimirov grad") because he is generally credited as the founder.
