Otto Albert Adelaide Facie Agnes Henry II Frederick Adelheid Conrad Mechtild Ernest I William Richardis Margaret John I Henry I (August 1267 – 7 September 1322), Duke of Brunswick-Lüneburg, called the Admirable (, ), a member of the House of Welf, was the first ruler of the Principality of Grubenhagen from 1291 until his death.

Life

He was the eldest son of the Brunswick duke Albert the Tall and his second wife Adelaide, daughter of Margrave Boniface II of Montferrat. His father had ruled the Duchy of Brunswick-Lüneburg jointly with his brother John, until both divided their territory in 1269. Albert went on to rule the Principality of Wolfenbüttel until his death in 1279.

Henry first ruled the Brunswick principality of Wolfenbüttel jointly with his younger brothers Albert II the Fat and William. In 1291 they again divided the territory; Henry received the part that came to be known as Principality of Grubenhagen. It included the cities of Einbeck, half of Hamelin, Clausthal, Amelungsborn, Duderstadt, Herzberg, and Osterode. Henry quarreled with his brother Albert, who had received the Principality of Göttingen, over the remaining belittled areas around Brunswick and Wolfenbüttel, 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.
