From the end of the 7th century to the 3rd century BC, the Scythians occupied the steppe from the north Black Sea area, from the Don in the east to the Danube in the west. Among all those Scythians tribes, the most distinguishing tribe is called the Royal Scythians. With the Royal Scythians playing the dominant role, nomad Scythians, the Callipidae, the Alizones, agricultural Scythians and ploughing Scythians hold a submissive position. While the Royal and Nomad scythians led the nomadic lives, the Callipidae and Alizones lived in semi-nomadic style. Of course ploughing Scythians definitely were sedentary agriculturalists. According to Herodotus, the Callipidae or the Graeco-Scythians lived not far from Olbia, at the mouth of the Bug. To the north, there lived the Alizones; and further north the ploughing Scythians covered the area between the Dnieper and Bug. The Nomad Scythians occupied the steppes of the Azov Sea area and the left and right banks of the Dnieper. Most scholars believe that both banks of the lower Bug as far as the River Konka were the lands of the Nomad Scythians while the Royal Scythians roamed lands further east and south as far as the Don. Lastly the nomadic Scythians occupied at the Altai region of Siberia are called Kindred Scythians or Eastern Scythians.
It was during the 4th century BC. that the Scythian kingdom reached the hightest economic, political, social and cultural development. Many nomads bacme sedentary in the north Black Sea and Kamenskoe Gorodishche was the economic, political and trading capital of Scythia in the 4th till the first half of the 3rd century BC. The great king Atheas united all the Scythian tribes and expanded his territory to Tracian border on the rigth bank of the Danube. In 339 B.C., Atheas was killed at age of 90 in the battle with Philip of Macedon. However the Scythian kingdom remained strong and wealthy. The outside threat did not disturb their stability until the Celts and the Thracians swept in from the west and the Sarmatians from the east starting at the second half of the 3rd century BC.; the Scythian kingdom was absorbed by other nomdic powers and pretty much disappeared in the history.
