Rus is what these people called themselves. They were folks lured to that part of the Mediterranean by promise of work in the Byzantine military as Varangian Guards.
A subset of these Norsemen sailed up the Dniper to what is today Kiev and setup Kievan Rus. They ruled over and assimilated the the Slavic, Bulgar, and Turkic peoples of the area. In the Middle Ages, the Mongols came and destroyed Kiev, murdering just about everyone inside, leading to fragmentation into multiple polities like Moscow, the Novgorod Republic, and Vladimir.
The Rus ethnonym lives on in the name of the Russians, Rusyns, Ruthenians, Belarussians, and others!
