House of Waldburg
Waldburg is a princely family of Upper Swabia, founded some time previous to the 12th century; the cadet lineages are comital families. Eberhard von Tanne-Waldburg (? - 1234) was the steward, or "seneschal", and adviser of the Staufen dukes of Swabia, and later the adviser of the Emperor Friedrich II. During the anti-Staufen uprising, he and his brother Friedrich von Tanne took opposing sides. Friedrich was killed in 1197 in Montefiascone and Eberhard became the guardian of his nephew, Heinrich, until 1220. Subsequently, he and his nephew administered Swabia during the absence of the emperors. He was  entrusted with the imperial regalia that was kept at Waldburg from 1220–1225, hence the name "seneshal," or "steward". Eberhard was the founding "father" of the Waldburg lines, and from him the medieval, early modern, and modern lines descend. History. Alttrauchburg. In 1258 the fief of Alttrauchburg had been given to the stewards of Waldburg, who purchased it outright in 1306 from the count, who had run into debt. The tower-like core structure was now extended and built on. To the south, the large outer bailey was laid out together with its strong, rectangular, advanced tower. As a result, the  Waldburgs mostly lived in the castle by themselves or let had it managed by vogts (1418 Hans von Mühlegg). In 1429, the Trauchburg went to the Jacobian line of the family. Some lords are referred to in the sources as "bad stewards", i.e. were in constant financial difficulties. As a result of suffering capture and damage in various conflicts, the castle of Alttrauchburg was expanded and strengthened in the 16th century and upgraded into a representative seat of territorial lordship and government. In 1628, the Waldburgs became imperial counts and moved in 1690 to their "schloss" at Kißlegg, abandoning their  seat at Trauchburg and using it as a quarry for the new "schloss" at Kißlegg. In 1772 the Jacobian line of the Waldburgs died out with Count Francis Charles Eusebius. The estate went to the line of the counts of Waldburg-Zeil and the castle is still owned by this family today.
