Burchard I of Swabia Duke

  Notater:

Burchard I (died 5 or 23 November 911) was the Duke of Alamannia from 909 to his death and margrave of Raetia Curiensis, as well as Count in the Thurgau and Baar. Born between 855 and 860, he was the son of Adalbert II, Margrave of Tuscany, Count in the Thurgau. Burchard 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 or 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.

Burchard blev gift med Luitgard von Sachsen, datter af Liudolf von Sachsen Duke og Oda, i 882. (Luitgard von Sachsen blev født omkring 845, døde den 17 Nov. 885 og blev begravet i Aschaffenburg, , Bayern, Germany.)
