“The proximate causes of the Flemish “peasant” revolt were local and immediate; its roots, the reason it could occur in the first place, were four centuries in creation. As Europe’s population increased threefold between the ninth and thirteenth centuries, the Continent’s demographic pyramid changed its shape. The base grew larger relative to its peak, and more distant: the gap between nobility and peasantry got bigger and bigger. Families that were noble by birth became more and more “noble” in behavior: dressing more opulently, entertaining more lavishly, and housing themselves more extravagantly, while the rural peasantry lived more or less the same as their many times great-grandparents.”

Justinian tells his interlocutor, “I would have you baptized in the name of one God” only to receive the response, “I am baptized in One God,” evidently an attempt to contrast his Monophysite sympathies with the emperor’s orthodoxy. The Green spokesman accuses the emperor of suppressing the truth, of countenancing murder, and when he has had enough, he ends with “Goodbye Justice! You are no longer in fashion. I shall turn and become Jew; better to be a pagan than a Blue, God knows…”14 The most telling part of the entire dialogue, however, is that it was”
