Facts and Events
He was a son of William, Duke of Brunswick-Lüneburg (1535–1592) and Dorothea of Denmark (1546–1617). His mother was daughter to Christian III of Denmark and Dorothea of Saxe-Lauenburg. She acted as a regent during the early years of his reign, keeping power from the councillors who had mismanaged the estates during his father's fits of insanity.
In the 1635 redivision of the territories of the House of Welf after the death of Frederick Ulrich of Brunswick-Lüneburg, he received the Principality of Calenberg, which included the former Principality of Göttingen since 1495, while his elder brother Augustus retained the Principality of Lüneburg. George was the first duke to move his residence to Hanover where he laid the foundation for the Leineschloss. After his death, he was succeeded by his son Christian Louis.
