The Black Death was a bubonic plague pandemic, which reached England in June 1348. It was the first and most severe manifestation of the second pandemic, caused by Yersinia pestis bacteria. The term Black Death was not used until the late 17th century.
Originating in Asia, it spread west along the trade routes across Europe and arrived on the British Isles from the English province of Gascony. The plague was spread by flea-infected rats, as well as individuals who had been infected on the continent. Rats were the reservoir hosts of the Y. pestis bacteria and the Oriental rat flea was the primary vector.
The first-known case in England was a seaman who arrived at Weymouth, Dorset, from Gascony in June 1348. By autumn, the plague had reached London, and by summer 1349 it covered the entire country, before dying down by December. Low estimates of mortality in the early 20th century have been revised upwards due to re-examination of data and new information, and a figure of 40–60% of the population is widely accepted.
The most immediate consequence was a halt to the campaigns of the Hundred Years' War. In the long term, the decrease in population caused a shortage of labour, with subsequent rise in wages, resisted by the landowners, which caused deep resentment among the lower classes. The Peasants' Revolt of 1381 was largely a result of this resentment, and even though the rebellion was suppressed, in the long term serfdom was ended in England. The Black Death also affected arti
Why this event still matters
Historical incidents shape the rules that protect people today — building codes, evacuation policy, warning systems and inspection regimes almost always trace back to a specific disaster. Studying Black Death in England alongside current events is how preparedness improves.
