Heinrich I. (Braunschweig-Grubenhagen)

from Wikipedia, the free encyclopedia

Duke Heinrich von Braunschweig-Lüneburg , Prince of Braunschweig-Grubenhagen, called the miraculous (Mirabilis) (* August 1267 ; † September 7, 1322 at the Heldenburg ) was the first duke of the newly founded principality of Grubenhagen since 1291 . The name Grubenhagen was only created around 1617, the previous name of the principality is unknown.

Life

Heinrich was a son of Duke Albrecht I of Braunschweig-Lüneburg . When he died in 1279, his three sons had to share the Braunschweig inheritance. After an inheritance dispute, they came to an agreement in 1290. In 1291, Duke Heinrich received the newly formed principality of Grubenhagen with the towns and castles of Einbeck , Osterode am Harz , Herzberg am Harz and Duderstadt .

Heinrich went down in history as the founder of the Grubenhagener Guelph line . Due to the previous inheritance disputes, the Grubenhagener Guelphs were only allowed to call themselves dukes of Braunschweig, Lüneburg as part of their name was only assigned to them in the 16th century. His younger brother Albrecht the Feiste continued the Braunschweig-Wolfenbüttel line as Duke Albrecht II , and his youngest brother Wilhelm inherited the House of Braunschweig .

The government of Heinrich in Grubenhagen is surrounded by many legends. It is known that Heinrich led many unsuccessful feuds that resulted in deep financial difficulties. Nevertheless, he donated to monasteries and monasteries in Pöhlde, Katlenburg and Osterode, as well as St. Alexandri in Einbeck. Hence his nickname the whimsical .

He was a popular and well-known prince, to whom the Saxon count palatine was given by the king in 1291 . Heinrich was considered by some imperial princes and electors as a possible successor to King Rudolf I of the House of Habsburg . In his place, however, the relatively unknown Count Adolf von Nassau was elected king in 1291 .

He was a main character in the Herlingsberg War .

Heinrich died in 1322 and was buried in Brunswick Cathedral . His sons divided the duchy among themselves; Heinrich became Duke de Graecia (of Greece ), his second son Ernst became Duke of Osterode and his youngest son Wilhelm became Duke of Herzberg. The Duchy of Grubenhagen was only reunited with Duke Albrecht II († 1485).
