Croatian nobility in the context of "Zrinski family"

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.

Coloman the Learned, also the Book-Lover or the Bookish (Hungarian: Könyves Kálmán; Croatian: Koloman; Slovak: Koloman Učený; c. 1070 – 3 February 1116), was King of Hungary from 1095 and King of Croatia from 1097 until his death. Because Coloman and his younger brother Álmos were underage when their father Géza I died, their uncle Ladislaus I ascended the throne in 1077. Ladislaus prepared Coloman—who was "half-blind and humpbacked", according to late medieval Hungarian chronicles—for a church career, and Coloman was eventually appointed bishop of Eger or Várad (Oradea, Romania) in the early 1090s. The dying King Ladislaus preferred Álmos to Coloman when nominating his heir in early 1095. Coloman fled from Hungary but returned around 19 July 1095 when his uncle died. He was crowned in early 1096; the circumstances of his accession to the throne are unknown. He granted the Hungarian Duchy—one-third of the Kingdom of Hungary—to Álmos.

In the year of Coloman's coronation, at least five large groups of crusaders arrived in Hungary on their way to the Holy Land. He annihilated the bands who were entering his kingdom unauthorized or pillaging the countryside, but the main crusader army crossed Hungary without incident. He invaded Croatia in 1097, defeating its last native king Petar Snačić. Consequently, he was crowned king of Croatia in 1102. According to the late 14th-century Pacta conventa (the authenticity of which is not universally accepted by scholars), he was only crowned after having ratified a treaty with the leaders of the Croatian nobility. For centuries thereafter, the Hungarian monarchs were also the kings of Croatia.

The Austrian nobility (German: österreichischer Adel) is a status group that was officially abolished in 1919 after the fall of Austria-Hungary. Austria's system of nobility was very similar to that of Germany (see German nobility), as both countries were previously part of the Holy Roman Empire (962–1806).

Any noble living in the Habsburg-ruled lands, and who owed allegiance to the dynasty and therefore to the emperor, was also considered part of the Austrian aristocracy. This applied to any member of the Bohemian, Hungarian, Polish, Croatian, and other nobilities in the Habsburg dominions. Attempting to differentiate between ethnicities can be difficult, especially for nobles during the eras of the Holy Roman Empire and the Austro-Hungarian monarchy (1867–1918). A noble from Galicia, for instance, such as the Count Jordan-Rozwadowski (see section "Noble titles" below under Graf/Gräfin (count/countess)), could call himself a Polish noble, but he also rightfully belonged to the Austrian nobility.

Pacta conventa (lit. 'agreed accords') was an agreement concluded between King Coloman of Hungary and the Croatian nobility in 1102 or afterwards, defining the status of Croatia in the union with Hungary. The earliest manuscript of the document is of the fourteenth century, so some historians believe it is likely a forgery.

The document titled Pacta conventa or Qualiter (the first word in the document) was found in a Trogir library. Until the 19th century it was considered that it dated to 1102. However, historians today hold that it is not an authentic document from 1102 and likely a forgery from the 14th century, but that the contents of the Pacta Conventa still correspond to the political situation of that time in Croatia. The document is preserved in the Hungarian National Museum in Budapest.
