London plagues 1348–1665
Many people have heard of the Black Death of 1348 and the Great Plague of
1665: both terrible outbreaks of a disease which killed thousands of Londoners.
However, it is less well-known that these famous outbreaks are only two of
nearly 40 that London suffered between 1348 and 1665.
A major outbreak of the disease struck roughly every 20-30 years, killing around
20% of London’s population each time. There were lesser outbreaks in-between
the major ones and sometimes the disease could continue for several years in a
less serious form.
What is ‘plague’?

There is still debate about what these ‘plagues’ actually were. Most experts believe that the
plague that struck London from the 1300s to the late 1600s was bubonic plague. Bubonic
plague is a disease of rodents, especially black rats. It is passed between them by bites from
their fleas. When a rat dies from the plague, its fleas must find a new host to live on. If their
new host is a person, the disease can spread to humans too. If this happens, 60–80% of
those with the disease die, most within a week. Plague can spread quickly within a
household, as this picture shows. In it several people are lying ill in bed while being cared
for by nurses.
The French doctor Alexandre Yersin discovered the bacterium that causes
bubonic plague in 1894. In 1908 experts realised that rat fleas spread plague.

• fever
• vomiting
• painful swellings on the neck,
armpits and groin (buboes)
• blisters and bruises
• coughing up blood.
The disease takes many forms but the
most common symptoms are:

In 1347 news reached England of a horrifying
and incurable disease that was spreading from
Asia through North Africa and Europe. The Black
Death struck London in the autumn of 1348.
No one knew how to stop the disease. During the
next 18 months it killed half of all Londoners –
perhaps 40,000 people.
There were so many dead that Londoners had
to dig mass graves (large trenches for many
bodies). This picture shows one of these graves,
which was excavated by archaeologists at the
Royal Mint site near the Tower of London. In
some of the trenches, the bodies were piled
on top of each other, up to five deep. Children’s
bodies were placed in the small spaces between
adults. By 1350 the Black Death had killed
millions of people, possibly half the population
of the known world.

The term ‘Black Death’ was first used in the 1800s. Medieval people called the
disease the ‘Great Pestilence’.
Many people believed the plague spread through bad air so they smoked
tobacco to stop any bad air entering their lungs.
After the Black Death, plague returned to London many times until its
last major outbreak in 1665. The disease usually spread from Asia or
the Middle East across Europe to England. People were particularly
frightened of the plague because its victims died so quickly and very
few recovered. The worst bout of plague was in 1563, when 24%
(nearly a quarter) of London’s population died.

In 1518 the first regulations to stop plague were introduced in
London. A bale of straw had to be hung on a pole outside
infected houses for 40 days. People from infected homes had
to carry a white stick when they went out to warn others to
stay away. More rules were gradually added over the years,
such as putting a cross on the door of plague-ridden houses,
only burying the dead at night, and ringing a bell like this one
for 45 minutes for each burial. The noise of bells ringing
during burials was meant to remind people to follow the
plague prevention rules.

The Great Plague of 1665 was the last major plague in England. The outbreak began in
London in February. Within seven months 100,000 Londoners (20% or one-fifth of the
population) were dead. Many fled the capital to escape the disease. Victims were shut in
their homes and a red cross was painted on the door with the words ‘Lord have mercy
upon us’. The theatres and other public entertainments such as football were banned to
stop the disease spreading.
Every week, each London parish recorded the number of people who had died. The
numbers from all the parishes were added up and printed in lists called mortality bills.
This is a bill from the week in September which had the highest total of plague dead:
7,165 people. From then on the number of people dying gradually dropped. By December
the people who had fled the plague started to move back to London and life slowly
returned to normal.
People thought that animals might spread the disease so strays were killed by
special dog killers – around 40,000 dogs and 200,000 cats were slaughtered.
