used since the accession of the
House of Ascania to the dukedom in 1180, comprising the Ascanian arms with an added bendwise
crancelin indicating the Saxon ducal rank The new dukes replaced the Saxon horse emblem () and introduced their Ascanian family colours and emblem () added by a bendwise crancelin, symbolising the Saxon ducal crown, as new coat-of-arms of Saxony (). The later rulers of the
House of Wettin adopted the Ascanian coat-of-arms. After the division, the counting of the dukes started anew. Though the first Ascanian duke is counted either as Bernard III (because of two predecessors of the same name before 1180) or as Bernard I, his successor,
Albert I is counted as the first, although before 1180 he had one predecessor of the same name,
Albert the Bear. ===

Partitions of Saxony under Ascanian rule Table of rulers (Note: Both lines follow the numbering established in this table until 1296, when they were created. From 1296 on, each line follows independently the succession of Saxon dukes until 1296) The male line of the Saxe-Lauenburgish Ascanians was extinguished in 1689, after Julius Francis' death. In spite of having left two daughters to inherit the rights to the duchy, the
House of Welf usurped the duchy, preventing the succession of the legitimate heiress,
Anna Maria Franziska of Saxe-Lauenburg, and resucceeded with its Brunswick and Lunenburg-
Celle line. In fact,
George William, Duke of Brunswick-Lüneburg was a great-great-grandson of
Magnus I through his great-grandmother
Dorothea of Saxe-Lauenburg. His descendants became
Monarchs of Great Britain from 1714 on. In 1814, after being deposed by various occupations in the
Napoleonic Wars, George III's son,
Regent George agreed to pass Saxe-Lauenburg to his Danish cousin in a general territorial realignment at the
Congress of Vienna. This cousin was
Frederick VI of Denmark, who changed the official colours of Saxe-Lauenburg to red and gold. The duchy changed hands again when, in 1865,
Christian IX of Denmark was deposed in
Second Schleswig War and resigned by
Treaty of Vienna; Saxe-Lauenburg passed to
William I of Prussia, to whom the
Estates of Saxe-Lauenburg offered the ducal throne. The coat-of-arms of Saxe-Lauenburg was changed to the colours red and silver, with a border in the Prussian colours of black and white. Both duke and estates decided to merge Saxe-Lauenburg into Prussia, as
district Duchy of Lauenburg, with effect from 1 July 1876. ===
House of Wettin=== The Ascanian line of Saxe-Wittenberg became extinct with the death of Elector
Albert III in 1422, whereafter Emperor
Sigismund bestowed the country and electoral dignity upon Margrave
Frederick IV of Meissen, who had been a loyal supporter in the
Hussite Wars. Late Albert's Ascanian relative Duke
Eric V of Saxe-Lauenburg protested in vain. Frederick, now one of the seven Prince-electors, was a member of the
House of Wettin, which since 1089 had ruled over the adjacent
Margraviate of Meissen up the Elbe river, established under Emperor
Otto I in 965, and since 1242 also over the Landgraviate of
Thuringia. Thus, in 1423, Saxe-Wittenberg, the Margraviate of Meissen and Thuringia were
united under one ruler, and the unified territory. gradually received the name of (Upper) Saxony (or simply
Saxony).
