Árpád dynasty in the context of Turul

The Kingdom of Hungary was a monarchy in Central Europe that existed for nearly a millennium, from 1000 to 1946. The Catholic kingdom emerged as a continuation of the Grand Principality of Hungary upon the coronation of the first king Stephen I at Esztergom around the year 1000; his family (the Árpád dynasty) led the monarchy for 300 years. By the 12th century, the kingdom had become a European power.

Due to the Ottoman occupation of the central and southern territories of Hungary in the 16th century, the country was partitioned into three parts: the Habsburg Royal Hungary, Ottoman Hungary, and the semi-independent Principality of Transylvania. The House of Habsburg held the Hungarian throne after the Battle of Mohács in 1526 continuously until 1918 and also played a key role in the wars against the Ottoman Empire and the eventual expulsion of the Turks during and after the Great Turkish War.

The Grand Principality of Hungary or Duchy of Hungary (Hungarian: Magyar Nagyfejedelemség: "Hungarian Grand Principality", Byzantine Greek: Τουρκία) was the earliest documented Hungarian state in the Carpathian Basin, established in 895 or 896, following the 9th century Magyar invasion of the Carpathian Basin.

The Hungarians, a semi-nomadic people, formed a tribal alliance led by Árpád (founder of the Árpád dynasty) who arrived from Etelköz, their earlier principality east of the Carpathians.

Árpád (Hungarian pronunciation: [ˈaːrpaːd]; c. 845 – c. 907) was the head of the confederation of the Magyar tribes at the turn of the 9th and 10th centuries. He might have been either the sacred ruler or kende of the Hungarians, or their military leader or gyula, although most details of his life are debated by historians, because different sources contain contradictory information. Despite this, many Hungarians refer to him as the "founder of our country", and Árpád's preeminent role in the Hungarian conquest of the Carpathian Basin has been emphasized by some later chronicles. The dynasty descending from Árpád ruled the Kingdom of Hungary until 1301.

Stephen I, also known as King Saint Stephen (Hungarian: Szent István király [ˌsɛnt ˈiʃtvaːn kiraːj]; Latin: Sanctus Stephanus; Slovak: Štefan I. or Štefan Veľký; c. 975 – 15 August 1038), was the last grand prince of the Hungarians between 997 and 1000 or 1001, and the first king of Hungary from 1000 or 1001 until his death in 1038. The year of his birth is uncertain, but many details of his life suggest that he was born in, or after, 975, in Esztergom. He was given the pagan name Vajk at birth, but the date of his baptism is unknown. He was the only son of Grand Prince Géza and his wife, Sarolt, who was descended from a prominent family of gyulas. Although both of his parents were baptized, Stephen was the first member of his family to become a devout Christian. He married Gisela of Bavaria, a scion of the imperial Ottonian dynasty.

After succeeding his father in 997, Stephen had to fight for the throne against his relative, Koppány, who was supported by large numbers of pagan warriors. He defeated Koppány with the assistance of foreign knights including Vecelin, Hont and Pázmány, and native lords. He was crowned on 25 December 1000 or 1 January 1001 with a crown sent by Pope Sylvester II. In a series of wars against semi-independent tribes and chieftains—including the Black Hungarians and his uncle, Gyula the Younger—he unified the Carpathian Basin. He protected the independence of his kingdom by forcing the invading troops of Conrad II, Holy Roman Emperor, to withdraw from Hungary in 1030.

The Kingdom of Croatia (Modern Croatian: Kraljevina Hrvatska, Hrvatsko Kraljevstvo; Latin: Regnum Croatiæ), and since 1060 known as Kingdom of Croatia and Dalmatia (Latin: Regnum Croatiae et Dalmatiae), was a medieval kingdom in Southern Europe comprising most of what is today Croatia (without western Istria, some Dalmatian coastal cities, and the part of Dalmatia south of the Neretva River), as well as most of the modern-day Bosnia and Herzegovina. The Croatian Kingdom was ruled for part of its existence by ethnic dynasties, and the Kingdom existed as a sovereign state for nearly two centuries. Its existence was characterized by various conflicts and periods of peace or alliance with the Bulgarians, Byzantines, Hungarians, and competition with Venice for control over the eastern Adriatic coast. The goal of promoting the Croatian language in the religious service was initially introduced by the 10th century bishop Gregory of Nin, which resulted in a conflict with the Pope, later to be put down by him. In the second half of the 11th century Croatia managed to secure most coastal cities of Dalmatia with the collapse of Byzantine control over them. During this time the kingdom reached its peak under the rule of kings Peter Krešimir IV (1058–1074) and Demetrius Zvonimir (1075–1089).

The state was ruled mostly by the Trpimirović dynasty until 1091. At that point the realm experienced a succession crisis and after a decade of conflicts for the throne and the aftermath of the Battle of Gvozd Mountain, the crown passed to the Árpád dynasty with the coronation of King Coloman of Hungary as "King of Croatia and Dalmatia" in Biograd in 1102, uniting the two kingdoms under one crown.

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.
