One of the worst atrocities committed in the name of religion must surely be the sacking of Constantinople by Christian crusaders in the year 1204.
The city of Constantinople had been the capital of the eastern half of the Roman Empire since the emperor Constantine – the first emperor to embrace Christianity. it had been “The City” of the early Middle Ages rivalled by none.
Yet by the Fourth Crusade, the eastern Roman Empire – or Byzantine Empire as it’s more commonly called though it was never called that at the time – was in a slow decline. The lands it had once ruled in Egypt and the Levant were now under Muslim control and the Balkans had mostly slipped away.
But Constantinople – defended by huge walls – endured. That is until a wily, nonagenarian and blind Doge of Venice called Enrico Dandolo decided that the crusades shouldn’t attack their intended Muslim target but instead divert to Constantinople and sack it.
Why? Because the Byzantines had long been the commercial and political rivals of Venice. And the latter was in the ascendancy while the Byzantines were not the force they had once been. So why not kick them while they were down.
And so it came to pass that the city was put under siege and its walls breached. The destruction was on an epic scale and the Venetians stripped the place of all the booty they could carry.
That included the four horses you see on top of Saint Mark’s cathedral (well, they’re replicas and the real ones are now under cover). One statue taken back that tourists always seem to miss is a third or fourth century CE depiction of the last pagan Roman emperor Diocletian and his three co-emperors or “tetrarchs”.
This statue was obviously part of an ancient monument in Constantinople and was just unceremoniously slammed into a corner of Saint Mark’s cathedral where it looks weirdly out of place. But there it is – a piece of crusader/Templar booty. And most tourists walk past it without blinking.
