Great Plague of London
The Great Plague of London, lasting from 1665 to 1666, was the last major epidemic of the bubonic plague to occur in England. It happened within the centuries-long Second Pandemic, a period of intermittent bubonic plague epidemics that originated in Central Asia in 1331 (the first year of the Black Death), and included related diseases such as pneumonic plague and septicemic plague, which lasted until 1750.[1]
The Great Plague killed an estimated 100,000 people—almost a quarter of London's population—in 18 months.[2][3] The plague was caused by the Yersinia pestis bacterium,[4] which is usually transmitted to a human by the bite of a flea or louse.[5]
The 1665–66 epidemic was on a much smaller scale than the earlier Black Death pandemic. It became known afterwards as the "great" plague mainly because it was the last widespread outbreak of bubonic plague in England during the 400-year Second Pandemic.[6][7]
Preventive measures[edit]
Reports of plague around Europe began to reach England in the 1660s, causing the Privy Council to consider what steps might be taken to prevent it crossing to England. Quarantining (isolation) of ships had been used during previous outbreaks and was again introduced for ships coming to London in November 1663, following outbreaks in Amsterdam and Hamburg. Two naval ships were assigned to intercept any vessels entering the Thames estuary. Ships from infected ports were required to moor at Hole Haven on Canvey Island for a trentine – period of 30 days – before being allowed to travel up-river. Ships from ports free of plague or completing their isolation period were given a certificate of health and allowed to travel on. A second inspection line was established between the forts on opposite banks of the Thames at Tilbury and Gravesend with instructions to pass only ships with a certificate.[25]
The isolation period was increased to forty days – a quarantine – in May 1664 as the continental plague worsened, and the areas subject to quarantine changed with the news of the spread of plague to include all of Holland, Zeeland and Friesland (all regions of the Dutch Republic); restrictions on Hamburg were removed in November. Quarantine measures against ships coming from the Dutch Republic were put in place in 29 other ports from May, starting with Great Yarmouth. The Dutch ambassador objected at the constraint of trade with his country, but England responded that it had been one of the last countries introducing such restrictions. Regulations were enforced quite strictly, so that people or houses where voyagers had come ashore without serving their quarantine were also subjected to 40 days of quarantine.[26]
