Scythian name
Welcome to the Board.
Regarding to the Pod... it's difficult for a set of different nomadic tribes of various origins who lived in the Eurasian steppes, manage to organize in an organized state
in the steppes, at most would have a nomadic empire if and when a lord of war achieved to submit and follow against a weak tantalizingly rich and sedentary neighbor in internal difficulties convincing Hordes of converting an incursion into a permanent conquest, abandoning their nomadic life; so dear to them.
But the main problem is that they are only a comfortable Scythian name for contemporaries and historians call a set of tribal origins dissimilar ethnic groups who shared the same lifestyle, claiming descent from some mythical ancestor and nominally subject to any tribe and stronger than the other leader.
But the 'Scythians' of the European steppes are not the same as the 'Scythians' tribes of northern Persia or Bactria.
It's possible perhaps to conquer some Kingdom and avoid being assimilated for some time while creating an empire.
