Henry Julius was duke of BrunswickLneburg and prince of Wolfenbttel from 1589 until his death. In 1576 he had become the first rector of the Protestant University of Helmstedt.

Henry Julius was born in Hessen am Fallstein as the eldest son of Julius, Duke of BrunswickLneburg and his wife, Hedwig of Brandenburg. Already in 1566, at the age of two, he had been elected bishop of Halberstadt by the cathedral chapter however, a condition of his election was an agreement that the cathedral chapter would lead the Bishopric under its own authority until Henry Julius reached the age of 14. Hence he took over administration of the Bishopric in 1578, and became active as a temporal as well as spiritual ruler. He improved general education in the Bishopric, and completed the Protestant Reformation, although he allowed Catholic office holders to keep their privileges except that he strictly prohibited priests from having mistresses.
