Encyclopedia
Ernest I of Brunswick-Grubenhagen was Prince of Brunswick-Grubenhagen.
and William
jointly ruled the principality.
Grubenhagen was rather smaller than the other Guelph principalities. Because Henry the Admirable had many children (eight sons and eight daughters), it was this difficult to supply all the descendants in style. His eldest son Henry II
could therefore not take the undivided sovereignty over the principality. In 1324, Henry concluded an extensive pact with his brothers Ernest and William under which the territory should be governed jointly. Shortly afterwards, however, the principality was divided. Ernest received the area around Einbeck
, Grubenhagen Castle
and Osterode
. The towns of Duderstadt
, Osterode and Einbeck were ruled jointly. In 1359 he made his son Albert I
co-regent. His older brother Henry died 1351 and his sons lingered broad and died without issue, so after the death of his childless younger brother William in 1360, Ernest ruled the entire principality of Grubenhagen. After his death, on 9 March 1361, he was succeeded by his son Albert I
