from Wikipedia, the free encyclopedia

Adalbero von Eppenstein (* around 980; † November 28, 1039 in Ebersberg ) was Margrave of the Carinthian Mark (approx. 1000-1011) and Duke of Carinthia and Margrave of Verona (1011 / 1012-1035).


Adalbero came from the Eppenstein family, who were wealthy in the Enns and Mürz valleys . He was the son of Markwart III. and the Hadmud von Ebersberg , daughter of Count Adalbero. Through his marriage to Beatrix († after 1025), a daughter of Hermann II of Swabia from the Konradin family , he was related by marriage to Emperor Konrad II . Beatrix was the sister of Empress Gisela , another sister was Mathilde, the wife of Conrad I , who was Duke of Carinthia until 1011.

As the successor to his father Markwart, Adalbero was entrusted with the margravate in the Karantanermark around 1000 . He was also Count in the Ennstal and Judenburg (Count of Eppenstein). He also owned goods in the county of Mürz Valley. In 1012 King Heinrich II transferred the Duchy of Carinthia and the margraviate of Verona with Friuli / Carniola and Trento to him . Adalbero also took over the county of Gorizia and the protective vogtei over the Patriarchate of Aquileia . In 1012 Krain was spun off from the Duchy of Carinthia , and in 1025 Windische Mark an der Sann .

In 1019 Adalbero near Ulm was defeated in a dispute over the inheritance of his father-in-law by Konrad the Younger , who was allied with Konrad the Elder , and who had been passed over as Duke of Carinthia in his father's successor. Adalbero had to withdraw from Swabia. In 1003/1025 the first monastery in Carinthia, St. Georgen am Längsee , was founded. Adalbero became its first Vogt. He accompanied the emperor in 1027 and took part in the coronation of Henry III in Aachen . part and acted in September 1027 at the Synod of Frankfurt as the emperor's sword-bearer. He only reappears in the sources when he was deposed as Duke of Carinthia.

In May 1035, a break between Adalbero and Emperor Konrad II can be seen in the sources. The background cannot be illuminated; the accusation of high treason noted in the sources is not further explained. Adalbero lost all offices and fiefs in Bamberg in 1035. Immediately afterwards, the Carinthian mark fell to Count Arnold von Wels-Lambach . Carinthia was only given to Konrad the Younger on February 2, 1036 .

In 1036 Adalbero tried to fight his opponents in Carinthia. In revenge, he murdered the loyal margrave Wilhelm von Friesach-Zeltschach, lord of Sannmark and husband of Hemma von Gurk . He had to retreat to Ebersberg / Eresburg, the ancestral seat of his mother's house, and went into exile. He only returned after Konrad II's death. Henry III. but did not put him in his old dignity. In the monastery Geisenfeld Adalbero found his final resting place. His descendants are the cleric Adalbero , who later became Bishop of Bamberg (1053-1057), Count Markwart IV and perhaps the Willibirg. His rich allodial property remained with his son Markwart and formed the basis for the resurgence of his family.
