Johann I (Braunschweig-Lüneburg)
Johann I (around 1242; † December 13, 1277 ) was, together with his brother Albrecht I, the second duke of Braunschweig and Lüneburg until the division of the duchy in 1269 and the first regent of the newly created principality of Lüneburg .
Life
After the death of his father Otto I , Johann took over the government of the Duchy of Braunschweig-Lüneburg in 1252 together with his older brother Albrecht. In 1267 a division agreement was signed between the brothers, which was carried out in 1269. Johann received the Lüneburg land with the city of Hanover and the land between Deister and Leine, Albrecht the land around Braunschweig and Wolfenbüttel with areas in Calenberg and around Göttingen . Johann founded the so-called "Older House Lüneburg" , his brother the "Older House Braunschweig" . Through a feud with the Counts of Schwerin, he succeeded in acquiring the ownership rights to the Uelzen settlement , which he granted city rights in 1270 . In 1273 he gave the city of Lüneburg the monopoly on the salt trade in the principality, thereby significantly strengthening the city's economic development. Johann was buried in the St. Michaelis monastery in Lüneburg.
