Albert (Wolfenbüttel line) ruled the duchy jointly with his younger brother John (Lüneburg-Celle line). As the brothers could not agree on how to govern the duchy, in 1267 they decided to divide their possession, which happened in 1269. Albert partitioned the territory while John obtained the right to choose his part. He took the northern half including the cities of Lüneburg and Hanover while Albert received the southern part, including Calenberg, Helmstedt, the Harz mountain range and Göttingen. The City of Brunswick was to remain common property of the brothers.
