What was the Black Death?

Did bubonic plague really cause the Black Death? This was one of the questions tackled in BBC TV’s Decoding Disaster, which went out under the Timewatch banner.

What is certain is that the epidemic was one of the greatest, if not the greatest, disaster in history, killing perhaps 75 million people in Europe and Asia from 1346 to 1353 – 30 to 40 per cent of the population. The conventional explanation is that it was bubonic plague, carried by the fleas of the black rat, along with pneumonic and septicaemic plague which could be transmitted from person to person.

Sceptics, though, have suggested there were just not enough rats to spread the disease on the scale that happened, so other ideas have been suggested – notably anthrax or some kind of haemorrhagic plague, like Ebola. Others maintain that with a death toll on this scale, a number of different diseases must have been raging at the same time.

At the time, top academics at Paris University came up with their own explanation: a triple conjunction of Saturn, Jupiter and Mars in the 40th degree of Aquarius on 20 March 1345, but they were humble enough to acknowledge that some things were ‘hidden from even the most highly trained intellects.’

Black Death WAS plague - official

When I was at school, there was no doubt about it.   We were taught that the Black Death – perhaps the most lethal disease ever to afflict humanity – was bubonic plague.    Then some scientists came up with revisionist theories that it might have been an ebola-type virus, or anthrax, or some combination of infections.

Well now a group of Canadian researchers from McMaster University in Toronto believe they have proved the epidemic really was bubonic plague.   They analysed bones from the 14^th century, and were able to extract the plague bacterium, though in a different form from the one we know today.

They hope also to throw light on why the disease carried off so many.    From its first appearance in Central Asia in the 1330’s, it spread right across Europe and Asia, killing perhaps a third of the population.   In some places it was even more deadly.    Siena in Italy was said to have lost half of its people.  Nearby San Gimignano, with its famous towers, even more.

The Black Death was a dreadful blow to the prestige of the Church which had failed to warn the faithful that God was about to inflict this dreadful punishment on them.   It also produced a labour shortage, and as wages for the working class rose, the kings of England and France quickly imposed a wage freeze.
