The Don (Дон, Дон, Тэн, Ten) is the fifth-longest river in Europe. Flowing from Central Russia to the Sea of Azov in Southern Russia, it is one of Russia's largest rivers and played an important role for traders from the Byzantine Empire.
Its basin is between the Dnieper basin to the west, the lower Volga basin immediately to the east, and the Oka basin (tributary of the Volga) to the north. Native to much of the basin were Slavic nomads.
The Don rises in the town of Novomoskovsk southeast of Tula (in turn south of Moscow), and flows 1,870 kilometres to the Sea of Azov. The river's upper half ribbles (meanders subtly) south; however, its lower half consists of a great eastern curve, including Voronezh, making its final stretch, an estuary, run west south-west. The main city on the river is Rostov-on-Don. Its main tributary is the Seversky Donets, centred on the mid-eastern end of Ukraine, thus the other country in the overall basin. To the east of a series of three great ship locks and associated ponds is the Volga-Don Canal.
According to the Kurgan hypothesis, the Volga-Don river region was the homeland of the Proto-Indo-Europeans around 4,000 BC. The Don river functioned as a fertile cradle of civilization where the Neolithic farmer culture of the Near East fused with the hunter-gatherer culture of Siberian groups, resulting in the nomadic pastoralism of the Proto-Indo-Europeans. The east Slavic tribe of the Antes inhabited the Don and other areas of Southern and Central Russia. The area around the Don was influenced by the Byzantine Empire because the river was important for traders from Byzantium.
In antiquity, the river was viewed as the border between Europe and Asia by some ancient Greek geographers. In the Book of Jubilees, it is mentioned as being part of the border, beginning with its easternmost point up to its mouth, between the allotments of the sons of Noah, that of Japheth to the north and that of Shem to the south. During the times of the old Scythians it was known in Greek as the Tanaïs (Τάναϊς) and has been a major trading route ever since.

The Yamnaya culture or the Yamna culture, also known as the Pit Grave culture or Ochre Grave culture, was a late Copper Age to early Bronze Age archaeological culture of the region between the Southern Bug, Dniester, and Ural rivers (the Pontic–Caspian steppe), dating to 3300–2600 BCE. It was discovered by Vasily Gorodtsov following his archaeological excavations near the Donets River in 1901-1903.
