Upper Saxon Circle
The Upper Saxon Circle was an Imperial Circle of the Holy Roman Empire, created in 1512.
The circle was dominated by the electorate of Saxony and the electorate of Brandenburg. It further comprised the Saxon Ernestine duchies and Pomerania. The Lusatias that fell to Saxony by the 1635 Peace of Prague were never encircled.
