The Black Death killed nearly 2.5 million people in Britain between 1347 and 1350. Symptoms included swollen lymph nodes called buboes under the arms and groin, vomiting, skin patches from internal bleeding, and uncontrollable muscle spasms. Most victims died, though some survived if the buboes burst, releasing black pus. Explanations for the plague's cause included bad air, planetary alignment, and God's anger for sinful behavior like gambling and drinking. Between one-third and one-half of Europe's population perished, though higher wages and more available food improved life for plague survivors.
