As you know, the famous trade route (the route from the Varangians to the Greeks) connected the region of the Baltic Sea and Byzantium. Write the name of the rivers Oleg passed along and show the route that those who wanted to get to Byzantium could follow. Write the name of the seas that connected this route.

The trade route “From the Varangians to the Greeks” in the 9th-12th centuries connected the Baltic and Black Seas, or rather the Gulf of Finland, and against the Bosphorus. On it, goods from Byzantium went to the north, and goods from Northern Europe to the south. An example is the construction of the St. Sophia Cathedral in Novgorod in the middle of the 11th century, this was the expression of Byzantine influence, and in Byzantium itself in the 9th-11th centuries the Varangians sometimes became part of the emperor’s army.
If you look from south to north, the main river was the Dnieper, then the Volga (upper reaches), Lama (the city of Volokolamsk was founded on this path), from the upper Volga to the Western Dvina, and from it through Polotsk to the Baltic or through Msta to Lake Ilmen and further along the Volkhov, Ladoga Lake and Neva to the Gulf of Finland.
