Henry the Mild, Duke of Brunswick-Lüneburg

Henry of Brunswick-Lüneburg, Duke of Brunswick-Lüneburg, was called Henry the Mild. He was the prince of Lüneburg from 1388 to 1409 jointly with his brother Bernard I, Duke of Brunswick-Lüneburg, from 1400 to 1409, and also of Wolfenbüttel, and from 1409 until his death sole prince of Lüneburg.
Henry was the fourth son of Magnus with [the Necklace, Duke of Brunswick-Lüneburg]. He participated in the prosecution of the murderers of his brother Frederick, who was elected King of the Romans after 1400. Henry ravaged the Eichsfeld, a possession of the archbishop of Mainz, who was suspected of involvement in the murder. Only in 1405 was a peace ratified between Brunswick-Lüneburg and the Archbishopric.
In 1404, Henry was kidnapped by Bernard VI, Count of Lippe; when he paid a ransom, he was released, and later, with the support of King Rupert, took revenge on Bernard.
After the death of Gerhard, Count of Schleswig, Henry's sister's husband, Queen Margaret I of Denmark attempted to take control of Schleswig. However, Henry, together with Holstein, successfully defended Schleswig.
