Wilhelm I (Braunschweig-Wolfenbüttel)

from Wikipedia, the free encyclopedia
William the Victorious

Wilhelm , the Victorious , Duke of Braunschweig and Lüneburg (* 1392 ; † July 25, 1482 ) from the family of Guelphs was Prince of Lüneburg from 1416 to 1428 , from 1428 to 1432 and from 1473 to 1482, Prince of Braunschweig-Wolfenbüttel , from 1432 to 1473 Prince of Calenberg and from 1463 to 1473 Prince of Göttingen .


After the death of his father Heinrich in 1416, Wilhelm and his brother Heinrich the Peaceful took over the government of the Principality of Lüneburg. In 1428 the brothers and their uncle Bernhard, who ruled Wolfenbüttel, redistributed the Guelph property, in which the brothers Wilhelm and Heinrich were awarded the principality of Braunschweig-Wolfenbüttel, which was expanded to include the land between Deister and Leine , which later became the Principality of Calenberg Bernhard received the Principality of Lüneburg. After a common period of rule, they divided the area again in 1432. While Heinrich received the Wolfenbüttler Land, Wilhelm was resigned to the newly formed Principality of Calenberg. The rule that Wilhelm had received at that time still had no name. It consisted of the rights formerly belonging to the Principality of Lüneburg between Deister and Leine and the former County of Wölpe , the Reign of Hallermund and the Reigns of Homburg and Everstein . Since the Guelph princes all carried the title Duke of Braunschweig and Lüneburg and the areas they ruled were part of the duchy of Braunschweig-Lüneburg, the countries they ruled were named after the most important castle or city. Wilhelm often lived at Calenberg Castle and had the territory administered from here. This is probably why the name of the Principality of Calenberg came about during this time. Shortly afterwards, in 1442 or finally in 1463, Wilhelm succeeded in taking control of the Principality of Göttingen. In 1473 Wilhelm inherited the Principality of Wolfenbüttel from his sonless brother, but passed control of Calenberg to his sons Wilhelm the Elder.
