Henry II, Duke of Brunswick-Lüneburg

On their father's death in 1322, his sons agreed to rule the Principality of Grubenhagen jointly; but they finally divided up the territory, and Henry did not receive a part, and instead took over the administration of the brothers' joint property.

In 1327, Henry joined Louis IV, Holy Roman Emperor, when Louis traveled to Rome for his coronation.
