London's worst 2 years ever: 1665, 1666

 The Bubonic Plague of 1665-1666 had been known in Europe for cent­uries. In England, this was the worst out-break of plague since the Black Death of 1348.

It was the rat, attracted by impoverished, rubbish-filled city streets, that brought in the black rat-flea. It was the flea that carried bacteria and caused the plague. The Bubonic Plague created buboes i.e swellings in the lymph nodes found in the armpits, groin & neck, and victims experienced splitting headaches, vom­iting, swollen tongue and fever, turning the victim’s skin black.

Incubation took only 4-6 days and when the plague appeared in a household, the house was sealed, thus condemning the whole family to death! These houses were distinguished by a red cross and the words ‘Lord have mercy on us’ on the door.

The plague started in the Far East and quickly spread through Eur­ope. In London it began in the poor, overcrowded parish of St Giles-in-the-Field outside the city walls. In May 1665, only 43 people died. But the death rate began to rise during the hot summer months and at its peak in August, 31,160 people died. While 68,600 deaths were formally recorded in the city in 1665, the true number was probably 100,000, c15% of London’s population.

Sometimes whole communities died and corpses littered the streets, since there was no one left to bury them. In other places the corpses were brought out at night in answer to the cry,’ Bring out your dead’, put in a cart and taken away to the great gaping plague pits dug into the earth.

King Charles II and his Court fled for Hampton Court in Surrey, then to Oxford. People who could afford to send their families away from London in these months did so - most doctors, lawyers & merchants fled the city. So Parliament was postponed and had to sit in October at Oxford. Court cases were also moved from Westminster to Oxford.

The Lord Mayor of London and the aldermen remained in London to enforce the King’s orders to try and stop the spread of the plague. The poorest families had no choice but to remain in London with the rats and the plague victims. Watchmen locked and kept guard over infected houses. Parish officials provided food. Searchers looked for dead bodies and took them, always at night.

Consider the measures taken by King Charles II in response to the plague. All trade with London and other plague towns was stopped. The Council of Scotland declared that the border with England would be closed. There were to be no fairs or trade with other countries. This meant many people lost their jobs, including those who worked on the River Thames. Orders to the mayors ensured that no stranger was allowed to enter a town unless he had a formal Certificate of Health. No furniture was to be removed from an infected house. There were to be no public gatherings like funerals.

The plague spread across England. York was one city badly affected. The plague victims were buried outside the city walls and it is said that they have never been disturbed since then, as a pre­cau­tion against a resurgence of the dreaded plague. The grassy emb­ankments below the city walls are the sites of these plague pits.

Memorials were placed everywhere. In some towns and villages in England there are still the old market crosses which have a dep­res­sion at the foot of the stone cross for vinegar. In Derbyshire the small village of Eyam, 6 ms north of Bake­well, has a story of tragedy and courage that will always be remembered. The Plague Window in Eyam Church still recalls the era.

So how did the plague ever end? Did the black rat develop a greater resistance to disease? If the rats did not die, their fleas would not have needed to find a human host and fewer people would have been infected. And the humans who had not died also started to develop a stronger immunity to the dis­ease. After 1666, more effective quarantine methods were used for ships coming into the country.

King Charles II returned to London in Feb 1666, then the gentry returned. Tradesmen opened their businesses again, and life might have returned to normal. Then in Sept 1666 the Great Fire of London destroyed much of cent­ral London. Fortunately the fire also helped to kill off the black rats and fleas that had carried the plague bacillus. When the City was rebuilt after the Fire in brick and stone (not wood), the streets were widened and the open sewers were eradicated. This was the last major plague that London ever saw!

Read Daniel Defoe, A Journal of the Plague Year, 1722. And Samuel Pepys’ Diary gave a vivid account of London’s empty streets. The Lost City of London – Before the Great Fire of 1666 is an excellent blog.

I'm glad the village of Eyam is immortalised in stained glass. The villagers were brave.

Dear Helen, thank you for all these informations! Awful times - and awful hygienic conditions.

Though the feeling of being helpless is known to us now too - the news from Bergamo in the time of Corona - the lonely streets (The Rolling Stones wrote "Ghost Town) - impressions not that far away.
And shutting the doors of poor infected families: I read about plans (and it is said these are not fake news) that in case of a nuclear accident there are governmental plans that you can't leave your contaminated city neither.
Of course time changes, we have more progress in science, in our countries there is still wealth and comfort - but when I look around at the moment I have the impression that the "varnish of culture" is only extremely thin.
To overcome such pessimistic thoughts I concentrate on all the wonders that also happen - and my answer is thankfulness, for me the best way not to lose my joy of living.
Look around: here in Bavaria spring is starting, beauty all around us.
