‘War is the continuation of politics by other means.’ Although not all conflicts can – or should – be explained in such terms (some arising from emotional and irrational origins), this interpretation is basically sound and judicious; it is particularly apposite to the Middle Ages. Beyond the political objectives, we must also unearth the financial ones: these are rarely buried deeply but are frequently obscured by the noble ideals and moral justifications proclaimed by the warring protagonists. Politics means power means money. It is only rarely dangerous that too much cynicism is harmful to the process of historical interpretation; it is usually the case that the more cynical one is the closer one arrives at the historical truth.

I couldn’t agree more.
