The great scholar Ibnu Khaldun lived through the horrors of the Black Death wrote: the East and West was visited by a destructive plague which devastated nations and caused populations to vanish.
Outbreaks of bubonic plague have reached pandemic proportions on inly three occasions in recorded history:
*Known as Justinian’s Plague, spread through Middle East and the Mediterranean in the 6th century AD. The plague helped destroy the Roman Empire in the East.
*Black Death 14th century. Beginning in 1347, plague spread from western Asia to the Middle East and Europe include England, Scandinavia. The Black Death entered European when to struck a Mongol army attacking the city Kaffa. Within the first four years, no fewer than 20 million Europeans died.
*Emerged at the end of the 19th century, worldwide. Emerging from its wild rodent reservoir in the Himalayan borderlands between China and India soon after 1855 and travelling this time to east, infecting densely populated province of south China before attacking Canton and then the British colonial port of Hong Kong in 1894.
In 1905, the India Research Commission was established to carry out a comprehensive research programme, and some of Britain’s best medical scholars joined it.
They proved definitely that plague was basically a rodent disease and that infected populations of wild rodents functions as reservoirs of plaque contagion.
