The addition of a simple model of nomadic confederations to an agrarian demographic-structural model is discussed and it is shown that the nomadic invention and spread of horse cavalry in 700BCE from the Pontic-Caspian region substantially explains the size, spatial distribution, and duration of very large scale states of the scale of the Persian and Han empires.  The empires in India and western Europe arise as a secondary states. This model is compared and contrasted with historical data and with Turchin et. al’s 2013 PNAS model and Turchin’s 2009 theory of large-scale empires.
