Upper Saxony
Saxony-Wittenberg, in modern Saxony-Anhalt, became subject to the margravate of Meissen, ruled by the Wettin dynasty in 1423. This established a new and powerful state, occupying large portions of the present Free State of Saxony, Thuringia, Saxony-Anhalt and Bavaria (Coburg and its environs). Although the centre of this state was far to the southeast of the former Saxony, it came to be referred to as Upper Saxony and then simply Saxony, while the former Saxon territories in the north were now known as Lower Saxony (the modern term Niedersachsen deriving from this).
