Upper Saxony
It was particularly to distinguish the lands from 'Lower Saxony', a concept which arose later in popular usage (though never enforced) as a term for the original Saxon lands in north and west Germany (where Low German dialects had spread), in what is now the state of Lower Saxony, as well as the adjacent Westphalian region, Holstein and the western part of today's Saxony-Anhalt north of the Harz range (Eastphalia).
Lower Saxony
Lower Saxony ( (); ) is a German state ("Land") situated in northwestern Germany. It is the second-largest state by land area, with , and fourth-largest in population (7.9 million) among the 16 "Länder" federated as the Federal Republic of Germany. In rural areas, Northern Low Saxon (a dialect of Low German) and Saterland Frisian (a variety of the Frisian language) are still spoken, but the number of speakers is declining.
