Henry I, Duke of Brunswick
Duke of Brunswick-Lüneburg and Prince of Lüneburg

Henry the Middle (15 September 1468 – 9 February 1532), also known as “Heinrich der Mittlere” in German, was a member of the House of Welf and ruled as the Duke of Brunswick-Lüneburg. His official title was Duke of Brunswick-Wolfenbüttel, a principality within the Holy Roman Empire. Henry earned the nickname “the Middle” to distinguish him from other Henrys in the Welf dynasty.
Life
Henry of Brunswick-Lüneburg, the son of Otto V of Lüneburg and Anne of Nassau-Siegen, was born in 1468. In 1486, Henry took control of Lüneburg from his mother, who had been regent since the death of Henry's grandfather, Frederick II, Duke of Brunswick-Lüneburg. Henry's reign was marked by the complications relating to the Hildesheim Prince-Bishopric Feud. Henry was on the side of the bishop, and was against the nobility of Hildesheim and the Welfs of Brunswick. In 1519, Henry was victorious in the Battle of Soltau, though the intervention of the newly elected Emperor Charles V transformed the victory achieved on the battlefield into a defeat. Henry was on the side of the French during the election, and so earned the enmity of Charles V. Henry's two eldest sons became regents of the country, and Henry went into exile at the French king's court. Henry returned in 1527 during the beginning of the Reformation in Lüneburg, and tried to regain control of the land with help from those opposed to the Reformation.

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
