Henry I (946 – 15 October 1002), called the Great,[a] was Duke of Burgundy from 965 to his death and Count of Nevers through his first marriage.
He is sometimes known as Odo-Henry or Otto-Henry (in French Eudes-Henri), since his birth name was "Odo" and he only adopted "Henry" on being elected duke of Burgundy.
[1] As Odo, he entered the church at a young age and was a cleric at the time of the death of his brother Otto, Duke of Burgundy, on 22 February 965.
[2] He was elected by the Burgundian counts to succeed his brother and they gave him the name Henry.
[4] In 972, he married Gerberga, the widow of Adalbert II of Italy,[1] who had sought refuge at Autun.
