Notes:

Magnus (died 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 Sophie, 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.

Magnus attempted to secure the Principality of Lüneburg for his son Louis, so that it could be reunited with Wolfenbüttel. The prince of Lüneburg, William II, Duke of Brunswick-Lüneburg, a member of the same house to which Magnus belonged, the House of Welf, did not have sons; however, he had already promised the principality to a son of his daughter, a relative of the Duke of Saxony, before he agreed to Magnus' plan. Louis then married William's daughter Matilda. A lengthy conflict broke out that culminated in the Lüneburg Succession War, which was resolved only in 1388.

In 1367, Magnus joined Dietrich, Archbishop of Magdeburg, Albert, Bishop of Halberstadt, Valdemar, Prince of Anhalt, and others in a campaign against Gerhard of Berg, Bishop of Hildesheim; they were defeated by Hildesheim in a battle near Farmsen and Dinklar on 3 September. Magnus was taken prisoner, and had to buy his freedom. He died in Summer of 1369.

Notes:

The second son of Albert the Tall, Duke of Brunswick-Lüneburg, Albert was a boy when his father died in 1279. He was first under guardianship of his uncle, Conrad, Prince-Bishop of Verden, and then of his elder brother, Henry I, Duke of Brunswick-Lüneburg. In 1286 the three brothers divided their father's Principality of Wolfenbüttel; Albert received the areas around Göttingen, Minden, Northeim, Calenberg, and Hanover. He made Göttingen his residence, thus Principality of Göttingen. In 1292, the third brother, William, died childless, and Albert and Henry, who had received the Principality of Grubenhagen, quarrelled about William's share, the remaining belittled areas around Brunswick and Wolfenbüttel; Albert finally prevailed.

Notes:

Albert I of Brunswick was the second son of Otto the Child, the first Duke of Brunswick-Lüneburg. When his father died in 1252, he was the oldest surviving son, and took over the rule of the duchy; later his younger brother John joined him. In 1267, the brothers agreed to divide the duchy, which happened in 1269. Albert partitioned the territory while John obtained the right to choose his part. He took the northern half including the region of Lüneburg and the city of Hanover, while Albert received the southern part, including Calenberg, Helmstedt, the Harz mountains and Göttingen. The City of Brunswick was to remain common property of the brothers.

Albert died on August 15, 1279 and is buried at Brunswick Cathedral. He was succeeded by his elder three sons, the younger three joined the Church.
