Scythia

[4][5][6] The northern border of this Scythian kingdom were the dedicuous woodlands, while several rivers, including Don and Dnipro, flowed southwards across this region and emptied themselves into the Black Sea.

[7] Between the 9th and 5th centuries BC, the climate in the steppes was cool and dry, which was a catalyst for the emergence of equestrian nomadic pastoralism in the northern Pontic region.

[7] In these favourable climatic conditions grass grew abundantly on the treeless steppe and permitted the nomadic Scythians to rear large herds of cattle and horses.

The Scythian migration pushed the Agathyrsi westwards, away from the steppes and from their original home around Lake Maeotis,[9][10] and into the Carpathian region.

[7][15] In contemporary modern scholarship, "Scythian" generally refers to the nomadic Iranian people who dominated the Pontic steppe from the 7th century BC to the 3rd century BC, and the name "Scythia" is used to describe this region of the Pontic steppe inhabited by the Scythians.
