The Nisans (Latin: Niseni; Polish: Niżanie, Niszanie) were a Sorbian tribe that inhabited the basin of Elbe river, near the city of Dresden in modern Germany. Together with the neighboring Glomatians, Milceni, and other Sorbian tribes, they belonged to a wider Slavic group, known as the Polabian Slavs. Initially, Sorbian tribes were independent, but later fell under the supreme authority of Carolingian rulers and their successors. From 928 to 934, the East Frankish king Henry the Fowler conducted successful campaigns towards the Elbe regions, establishing outposts (March of Meissen) and imposing his rule over local Slavic tribes. In 984, according to the Thietmar's Chronicle, through the lands of Nisans and Glomatians, a pretender to the German throne Henry II, Duke of Bavaria was escorted by the army of Boleslaus II, Duke of Bohemia. In the following centuries, within boundaries of the March of Meissen, the region of Nisans (Latin: provincia Nisan; territorio Niseni) was still mentioned as a distinctive choronym (regional designation).
