Magnus II, Duke of Brunswick-Lüneburg

Magnus II, called Torquatus or Magnus of the Silver Chain (1328–25 July 1373), was the Welf duke of Brunswick-Wolfenbüttel and, briefly, Lüneburg. The eldest son of Magnus the Pious, he inherited Wolfenbüttel in 1369. Within months Duke William II of Lüneburg died too, having named Magnus his heir, a claim backed by Welf house law.

Emperor Charles IV instead treated Lüneburg as a vacant imperial fief and granted it to the Ascanian duke Albert of Saxe-Wittenberg, igniting the Lüneburg Succession War. Magnus's repeated demands for money drove the town of Lüneburg to side with his rivals, and his attempt to take it failed.

On 25 July 1373 he died of a wound received in a duel with his brother-in-law Count Otto I of Schaumburg at the Battle of Leveste.
