Grubenhagen
Grubenhagen was a Welf principality on the southwestern edge of the Harz, divided from Brunswick in 1291. In 1337 Henry II held its Einbeck portion, including Duderstadt.
The fragmented principality ceded Duderstadt to Mainz in 1366; one of its princes, Otto, married Queen Joan I of Naples in 1376. Philip I reunited the lands in 1526, but the line died out with Philip II in 1596. An imperial court awarded the territory to the Lüneburg branch in 1617.
