He was the second son of Louis III, Duke of Ohlau-Lüben-Goldberg, by his wife Margareta, daughter of Duke Bolko IV of Opole.
Their mother, Duchess Margareta, received Ohlau as a widow"s land. In 1443 both received Brieg from Elisabeth of Brandenburg, Duchess of Legnica-Brieg. The hard financial situation forced Henry X and John I to pledge their Duchy of Lüben to Duke Henry IX of Glogau in 1446.
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.
