Magnus I (1304–1369), called the Pious (Latin Pius), was duke of Brunswick-Lüneburg.
The son of Albert the Fat, Duke of Brunswick-Lüneburg, Magnus was still a minor when his father died in 1318; he and his brother Ernest were put under the guardianship of their elder brother Otto, who continued as sole ruler even after his brothers came of age. After marrying Sophia, a niece of Louis IV, Holy Roman Emperor, Magnus was appointed margrave of Landsberg and count palatine of Saxony by the Emperor in 1333. Magnus took residence at Sangerhausen. When Otto died in 1344, Magnus and Ernest jointly took over government of the state; but already on 17 April 1345, they agreed to divide the territory. Magnus received the Principality of Wolfenbüttel.
In 1346, a border war between Wolfenbüttel and the Archbishop of Magdeburg broke out. In exchange for help in this conflict, Magnus sold the Margraviate of Landsberg to Frederick II, Margrave of Meißen. But the Archbishop conquered Schöningen in 1347, and Magnus had to cede Hötensleben and some other possessions to the Archbishop. Financially ruined by the war, Magnus could not stop the cities in the state from acquiring more and more rights; especially the City of Brunswick was becoming more powerful.
In 1348, the Emperor gave Landsberg and the Palatinate of Saxony to Bernard, Prince of Anhalt. The ensuing conflict over these territories between Magnus and Bernard ended amicably with a marriage between Magnus' son Magnus and Catherine, daughter of Valdemar, Prince of Anhalt.
