Not the 1930s, but the 1230s: How medieval blood libels returned to poison our age

Nazism was top-down, a state machine of propaganda and genocide. What we see now is older, more insidious: grassroots libels, spread by self-anointed authorities

That London in 2025 requires a rally against antisemitism is shame enough. That it has had to be organised by Jewish groups and that the Labour government refused to send even a single representative only made matters worse.

The urgency is clear. A new survey shows antisemitism in Britain rising sharply. Particularly chilling is the growing number who now tell pollsters that Israel treats Palestinians “like the Nazis treated the Jews”. Such Holocaust inversion is doubly poisonous: it trivialises the Holocaust and retroactively justifies it by demonising Jews, accusing them of committing the very crimes they endured. Holocaust inversion turns Jew-hatred into a moral duty.

And yet this is not evidence that we are reliving the 1930s but rather the 1230s. Nazism was top-down: a state machine of propaganda and extermination. What we see now is older and more insidious. It is the medieval pattern revived: grassroots libels, spread by self-anointed authorities, rewarded by incentives, and eventually laundered into legitimacy when governments are pushed to echo them.

The parallels are disturbingly close. In the Middle Ages, the initiative usually came not from popes or kings but from local clerics and agitators. Illiterate populations relied on priests to tell them what to believe. Parish pulpits and monasteries turned rumour into revelation. Today, literacy is universal, yet the dynamic is the same. Today’s priests and agitators, our information gatekeepers, are NGOs, academics, journalists and UN rapporteurs. When they declare that Israel is “deliberately starving Gaza” or “committing genocide”, their followers believe it with the same fervour medieval congregants once brought to sermons about ritual murder.
