Henry I, Duke of Brunswick-Lüneburg

From Wikipedia, the free encyclopedia

Henry (1267 – 7 September 1322, Salzderhelden), Duke of Brunswick-Lüneburg, called the Admirable (Latin Henricus Mirabilis), was the first ruler of the Principality of Grubenhagen.

The eldest son of Albert I, Duke of Brunswick-Lüneburg, he first took over the state after his fathers death jointly with two of his brothers. In 1291 the brothers divided the territory; Henry received the part that came to be known as Grubenhagen. It included the cities of Einbeck, half of Hamelin, Clausthal, Amelungsborn, Duderstadt, Herzberg, and Osterode. Henry quarreled with his brother Albert over Brunswick, but Albert prevailed, and Henry retreated to Grubenhagen. He took Einbeck as his residence.

In 1320, Henry was appointed count palatine of Saxony by the emperor. He died in 1322, and his three surviving sons who had not joined the Church divided his territory among each other.
