Origins to early modern period

Turjak Castle (Auersperg Castle)

The former edelfrei family was first mentioned as Ursperch in a deed of 1162 issued by Duke Herman II of Carinthia at his residence St. Veit. The family's ancestral seat was Turjak Castle (German: Burg Ursperg, later Burg Auersperg) in the March of Carniola, according to an engraving on site built in 1067 by one Conrad of Auersperg. Above the engraving stands the original Auersperg coat of arms, displaying an aurochs (German: Auerochs(e) or Ur, Slovene: Tur). The family name may derive from Ursberg in Swabia, and their ancestors probably settled in Lower Carniola after the victory of King Otto I of Germany over the Hungarian forces at the 955 Battle of Lechfeld. They held large estates from Grosuplje in the north down to Velike Lašče and Ribnica, rivalling with the Meinhardiner counts of Görz, the Carinthian Ortenburg dynasty and the Patriarchs of Aquileia.

In the 13th century, the high noble line became extinct and was succeeded by a dynasty of ministeriales. In the mid 15th century, this line split into two eponymous branches with the brothers Pankraz II (1441–1496) and Volkhard VIII (1442–1508). The Auerspergs inherited the estate of Žužemberk and Šumberk in the Windic March, which passed on to a cadet branch. Pankraz II of Auersperg held Turjak Castle in the Duchy of Carniola and married Anne of Frankopan. His son Trojan (1495–1541) served at the Habsburg courts in Ljubljana and the Austrian capital Vienna as a Carniolan chamberlain and regent, Imperial Hofrat and commander during the Ottoman Siege of Vienna in 1529. Trojan's son Herbard VIII von Auersperg (1528–1575), called Hervard Turjaški in Slovene, was Carniolan Landeshauptmann and commander of the Croatian and Slavonian Military Frontier, he played a vital role as a patron of Primož Trubar, Jurij Dalmatin and the Protestant Reformation in the Slovene Lands. He received the noble rank of an Imperial Baron (Reichsfreiherr) in 1550, his descendants were elevated to Imperial Counts (Reichsgrafen) in 1630.

The Auersperg cadet branch, named after the castle of Šumberk in Lower Carniola, was influential throughout the 16th century. Wilhelm Auersperg (called "the Rich", cca. 1462–1507) and his nephew Hans (1480–1529) were regents (Landeshauptmann) of Carniola. Hans's son Wolfgang-Engelbert was considered one of the most educated noblemen in Carniola, and a strong supporter of Lutheranism.^[1] His son Andreas von Auersperg was one of the military commanders during the decisive Battle of Sisak against the Ottomans, gaining the nickname "Carniolan Achilles". In the early 17th century, the Šumberk cadet line, which was considered wealthier and more influential than the main one,^[2] died out; its estates were transferred back to the main line, and were later mostly inherited by the so-called "princely branch" of the family.

Count Johann Weikhard of Auersperg (1615–1677) served as head of the Aulic Council (Reichshofrat), as envoy of Emperor Ferdinand III in the negotiations preparing the 1648 Peace of Westphalia, and as a tutor to young King Ferdinand IV.^[3] Emperor Ferdinand III elevated Johann Weikhard to a hereditary Prince of the Holy Roman Empire in 1653 and enfeoffed him with the Silesian Duchy of Münsterberg in the Lands of the Bohemian Crown the next year. In 1663, Johann Weikhard received in pawn the lands of the extinct Counts of Tengen (Thengen), a Habsburg possession in Further Austria since 1522, and reached Imperial immediacy as Gefürsteter Graf with a seat in the Imperial Diet the next year.

The Duchy of Münsterberg was conquered by Prussia in the course of the First Silesian War with Austria in 1742, but the Auerspergs at first could retain their possessions as a Silesian state country. In 1791, Karl Joseph of Auersperg finally sold Münsterberg to King Frederick William II of Prussia. In the same year, Emperor Leopold II granted Karl Joseph the title of Duke of Gottschee and elevated the Auersperg-owned County of Gottschee to be the Duchy of Gottschee (German: Herzogtum Gottschee, Slovene: Kočevska Vojvodina). Upon the dissolution of the Holy Roman Empire in 1806, the Auersperg territory at Tengen was mediatised to the Grand Duchy of Baden.
