He was the second son ofLouis III, Duke of Ohlau-Lüben-Goldberg, by his wifeMargareta, daughter of DukeBolko IV of Opole.

In 1441, after the death of his father, Henry X and his older brother John I inherited the Duchies of Lüben and Haynau together as co-rulers. Their mother, Duchess Margareta, received Ohlau as a widow's land.

In 1443 both received Brieg fromElisabeth of Brandenburg, Duchess of Legnica-Brieg. The hard financial situation forced Henry X and John I to pledge their Duchy of Lüben to DukeHenry IX of Glogau in 1446. In 1450 they pledged Brieg, this time to their maternal uncle, DukeNicholas I of Opole. At the end, the brothers only retain Haynau and Strehlen (Strzelin), who ruled together until Henry X's death without issue, leaving John I as a sole Duke.
