How did Scandinavia influence the development of England, Kievan Rus?

A trade route from the Varangians to the Greeks passed through Ancient Rus, which connected Scandinavia with Byzantium through the rivers of eastern Europe, the Dnieper and the Western Dvina. The influence of Scandinavia on Russia was expressed both in dynastic marriages (Ingigerda is the wife of Yaroslav the Wise, Khristina Ingesdotter is the wife of Mstislav the Great, etc.) and in the participation of the Varangians in key events in Russia in the 9th-11th centuries (Sveneld, Asmud and others).

England until 1066 the Scandinavians regularly ravaged the British coast, from about 789 for the first time (the raid on the city of Dorset), and in 1066 the Norman conquest of England took place, which gave a powerful impetus to development.
