About Burchard I, duke of Swabia


Burchard I, Duke of Swabia

From Wikipedia, the free encyclopedia

Burchard I (died 5 or 23 November 911) was the duke of Swabia from 909 to his death and margrave of Rhaetia, as well as count in the Thurgau and Baar. Born between 855 and 860, he was the son of Adalbert II, count in the Thurgau. He himself married Liutgard of Saxony.

By 900, Burchard was already the most powerful man in Swabia. In 904, he was the administrator of the lands of the abbey of Lorsch in Swabia. He succeeded, around 909, Ruadulf (a Welf) as dux or marchio (duke of margrave) of Raetia Secunda (the borderlands of Rhaetia). Burchard entered into a conflict with the Count Palatine Erchanger and Bishop Solomon III of Constance, who were loyal to King Conrad I. Burchard was captured and charged with high treason. He was found guilty by the tribal council and executed, along with his brother, Adalbert III of Thurgau. His son, Burchard II, and daughter-in-law, Regelinda, left for Italy, either exiled or taking refuge. Their Rhaetian estates were lost, though later recovered. Burchard I's second son, Odalric, had already died young.

The state of Swabia relative to the other stem duchies was highly disorganized at the time of Burchard I and he was never duke in the sense of the later dukes. He is usually called such only to distinguish him as the most powerful man in the duchy and the forerunner of the later dukes: the first being Erchanger, proclaimed duke by the nobility, but not the king, in 915.

The primary source which confirms his parentage has not yet been identified. Markgraf in Rätien 891/911. "Hludowicus…rex" confirmed privileges to Kloster St Gallen by charter dated 24 Jun 903 in which among "fidelium nostrum" was listed "Purchart marchio Curiensis Rætiæ"[33]. "Hludowicus…rex" confirmed an exchange of properties between Kloster Fulda and Kloster Echternach after consulting "fidelium nostrorum comitum vero Kebeharti, Liutpoldi, Burcharti, Eginonis, Liutfredi, Iringi et Cunpoldi" by charter dated 19 Mar 907[34]. "Hludowicus…rex" donated property "in pago Palanichoge in comitatu Egenonis in loco Ingilinstat" to Hatto Archbishop of Mainz after consulting "fidelium nostrorum comitum vero Burchardi, Egenonis et Ysaac" by charter dated 8 Jun 908[35]. [Duke of Swabia]. Herimannus records the death in 911 of "Burchardus dux Alamanniæ…orto tumultu occisus est"[36].

m ---. The name of Burkhard's wife is not known.

Burkhard [I] & his wife had three children:

1. ULRICH (-30 Sep ----). The Annales Alamannicorum name (in order) "Purchardo et Uodalricho" as sons of "Purghart comes et princeps Alamannorum" specifying that they were expelled from Swabia when their father was killed in 911[38]. Graf im Zürichgau 902/[914/15]. Graf im Thurgau 912/17.

It is not certain that "Burchardi" refers to the duke of Swabia, although the charter is dated during the period during which the title dux was not consistently used in contemporary documentation and no other Burkhard has yet been identified to whom it can refer. He was killed during an expedition to northern Italy in support of his son-in-law Rudolf King of Burgundy[42]. Herimannus records that "Burghardus dux" was killed in 926[43]. The Annales Sangallenses specify that he was killed in Italy[44]. m (before 911) as her first husband, REGINLIND, daughter of [EBERHARD [I] Graf im Zürichgau] & his wife Gisela --- (-Ufenau Island 958 after 29 Apr).

Duke Burkhard II & his wife had three children:

He was installed in 954 as BURKHARD III Duke of Swabia after the duchy was confiscated from Liudolf, son of Otto I King of Germany.

The Casus Monasterii Petrishusensis records a donation by "Burchardus religios dux et Hadiwich eius coniunx", recording that they founded a monastery "in monte Duello"[56]. Her parentage is deduced from the Vita Oudalrici which records that the mother of the wife of "Purchardo duce Alamannorum" was "filiam materteræ" of "Heinricus filius Purchardi comitis" who was installed as Bishop of Augsburg in 973[57]. "Otto…rex" donated land "Scaleia…in pago Brisggouue in comitatu Birhtilonis" to the church at Worms by charter dated 18 Jun 990 on the petition of "Hadeuige ducis nostræ…consanguineæ"[58].

3. DIETPIRCH (-17 or 22 Mar after 923, bur Wittislingen). Dietpirch is named as wife of Hupald in the Vita S. Oudalrici[66].

aus Wikipedia, der freien Enzyklopädie

Burchard I. von Schwaben (* zwischen 855 und 860; † 5. November oder 23. November 911, hingerichtet) war Herzog von Schwaben (909-911), Markgraf in Rätien sowie Graf im Thurgau und der Baar.


Burchard wurde als Sohn des Grafen Adalbert II. des Erlauchten im Thurgau (825–905), Urenkel des Markgrafen Hunfried I. von Istrien und Rätien, und Judiths von Friaul (830–902) geboren. Aus seiner Ehe mit einer unbekannten Frau gingen die Kinder Burchard II., (* um 885; † gefallen 29. April 926 vor Novara) und Udalrich von Schwaben (* 884 oder 885; † unbekannt) hervor. Burchard trat um 909 die Nachfolge von Ruadulf aus dem Geschlecht der Welfen als Dux, Markgraf bzw. Comes für das Grenzgebiet der Region Rätien an. Burchard verwaltete zudem eine Grafschaft in der Baar.

Burchard war um 900 der mächtigste Herrscher in Schwaben. In einem Tauschvertrag von 904 findet man Burchard auch als Vogt der schwäbischen Güter des Klosters Lorsch. Um seine Macht auszuweiten, begann er gegen Pfalzgrafen Erchanger, einen treuen Untergebenen von Konrad I., und den Bischof Salomo III. von Konstanz, Abt des Klosters St. Gallen (→ Appenzell Ausserrhoden), zu intrigieren. Burchard wurde gefangen genommen und vom schwäbischen Landtag des Hochverrats angeklagt, man befand ihn für schuldig. Sein Sohn, Burchard II., und dessen Frau Regilinde konnten zu ihrer Verwandtschaft nach Italien fliehen, verloren aber den Besitz in Schwaben und Rätien. Burchard und sein Bruder Adalbert, der Graf von Thurgau, wurden im Jahre 911 hingerichtet.
