The Ascanian line of Saxe-Wittenberg had become extinct with the death of Elector Albert III in 1422, whereafter Emperor Sigismund bestows the country and electoral dignity upon Margrave Frederick IV of Meissen, who has been a loyal supporter in the Hussite Wars.

The late Albert's Ascanian relative Duke Eric V of Saxe-Lauenburg protests in vain.

Frederick, now one of the seven Prince-electors, is a member of the House of Wettin, which since 1089 has 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 are united under one ruler, and the unified territory will gradually receive the name of (Upper) Saxony.
