When the Welfs left in 1180, the Duchy of Saxony lost a lot of territory. Westphalia fell to the Archbishop of Cologne, while the Duchies of Brunswick and Lüneburg remained with the Welfs. The Ascanian Dukes had their base further east, near the Elbe, so the name Saxony moved towards the east. The post carve-up Saxony is therefore sometimes called the "younger Duchy of Saxony". Also the counting of its dukes its mixed up. While the first post carve-up duke is sometimes called Bernard III - because of two predecessors of the same name before 1180 - or Bernard I with his great-great-great-great grandson Bernard II being counted second. The second post carve-up duke Albert I is already usually counted as the first, although before 1180 he had one predecessor of the same name, his grandfather Albert the Bear.
