The earliest Byzantine record of the Rus' may have been written prior to 842. It is preserved in the Greek Life of St. George of Amastris, which speaks of a raid that had extended into Paphlagonia. Contemporary Byzantine presence of the Rus are the mentioned in the Frankish Annals of St. Bertin. These relate that Emperor Louis the Pious' court at Ingelheim, in 839, was visited by a delegation from the Byzantine emperor. In this delegation there were two men who called themselves Rhos (Rhos vocari dicebant). Louis enquired about their origins and learnt that they were Swedes. Fearing that they were spies for their brothers, the Danes, he incarcerated them.

In 860, from Kiev, that the Rus under Askold and Dir launched their first attack on Constantinople. The result of this initial attack is disputed, but the Varangians continued their efforts as they regularly sailed on their monoxyla down the Dnieper into the Black Sea. The Rus' raids into the Caspian Sea were recorded by Arab authors in the 870s and in 910, 912, 913, 943, and later. Although the Rus had predominantly peaceful trading relations with the Byzantines, the rulers of Kiev launched the relatively successful naval expedition of 907 and the abortive campaign of 941 against Constantinople, as well as Sviatoslav I's large-scale invasion of the Balkans in 968–971.

These raids were successful in the sense of forcing the Byzantines to re-arrange their trading arrangements; militarily, the Varangians were usually defeated by the superior Byzantine forces, especially in the sea and due to the Byzantines' use of Greek fire.
