Burchard III, Duke of Swabia

Burchard III (c. 915 – 12 November 973), a member of the Hunfriding dynasty,[1] was the count of Thurgau and Zürichgau, perhaps of Rhaetia, and then Duke of Swabia from 954 to his death.

He was often at the royal court and he accompanied Otto on his campaign against the Magyars and was present at the great Battle of the Lechfeld on 10 August 955.

At the Battle of the Po on 25 June, he defeated Berengar's son, Adalbert, and restored Italy to Ottonian control,[3] even the south Italian principalities were brought to heel by 972.

In 973, he died and was buried in the chapel of Saint Erasmus in the monastery on Reichenau Island in Lake Constance.

[5] Burchard built the great fortress atop the Hohentwiel, and Hedwig was the foundress of the monastery of St. George there, but their marriage remained childless.
