The name Black Death came from the colour of the swelling in the groin, armpit or neck. The person suffering went into a coma and dies soon after. In Europe an estimated 25 million people died. The plague reached Britain in 1348 and again in 1360 and the population may have been reduced by a half. ^[1]
