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).
Kingdom of Saxony
The Kingdom of Saxony (), lasting between 1806 and 1918, was an independent member of a number of historical confederacies in Napoleonic through post-Napoleonic Germany. The kingdom was formed from the Electorate of Saxony. From 1871 it was part of the German Empire. It became a Free state in the era of Weimar Republic in 1918 after the end of World War I and the abdication of King Frederick Augustus III of Saxony. Its capital was the city of Dresden, and its modern successor state is the Free State of Saxony.
