Albert II, Duke of Brunswick

Albert II, called the Fat (c. 1268–1318), was the second son of Duke Albert I of Brunswick-Lüneburg and Adelaide of Montferrat. The brothers ruled jointly after their father's death in 1279, and in 1284 Albert married Rixa of Werle. When the inheritance was divided in 1286, he received Göttingen and the lands around Hanover.

After his brother William died in 1292, a seven-year dispute with his brother Henry ended in Albert's favour, with Brunswick's support; Henry kept his principality of Grubenhagen.
