Philip II, Duke of Brunswick-Grubenhagen

Philip II (2 May 1533 – 4 April 1596), Duke of Brunswick-Lüneburg, a member of the House of Welf, was the last ruler of the Principality of Grubenhagen from 1595 until his death.

When he died in 1596, the Grubenhagen branch of the Welfs became extinct, whereafter the principality was occupied by Duke Henry Julius of Brunswick-Wolfenbüttel.

Duke Philip II was married to his cousin Clara of Brunswick-Wolfenbüttel (1532–1595), designated Abbess of Gandersheim, who had renounced her ecclesiastical office after the abbey had been occupied by Schmalkaldic troops in the course of the Protestant Reformation and plundered afterwards.

In 1617, after a prolonged legal case, Henry Julius's son Frederick Ulrich had to cede the former Principality of Grubenhagen to Duke Christian of Brunswick-Lüneburg.

Duke Philip's final resting place is next to his parents and brothers in the crypt of St. Giles Church in Osterode am Harz.
