Definition A: an epidemic is the rapid spread of infectious disease to a large number of people in a given population of a given area within a short period of time.
The expanding “Evil” Empire of Eurasia established during XIII-XIV centuries the road and seaway networks over long distances with key points at crossroads that turned into capitals of countries after the Empire disintegrated. This disintegration has lead to dramatic consequences for Europe and accelerated development of human civilization.
The plague disease is commonly present in populations of fleas carried by ground rodents, including marmots, in Central Asia, Kurdistan, Western Asia, Northern India and Uganda from which it spread to China and India.
The great waves of the plague originated in China and traveled along the Silk Road with allegedly “Mongol” armies and traders or it could have come via ship. By the end of 1346, the of plague had reached the seaports of Europe.
From Italy, the disease spread northwest across Europe, striking France, Spain, Portugal, and England by June 1348, then turned and spread east through Germany and Scandinavia from 1348 to 1350.
The plague struck various regions in the Middle East during the pandemic, leading to serious depopulation and permanent change in both economic and social structures. By autumn 1347, the plague reached Alexandria in Egypt, through the port’s trade with Constantinople, and ports on the Black Sea.
Black Death is a reflection of the extremely drastic measures in XIV-XV centuries undertaken “Evil” Empire of Eurasia to prevent further spread of plagues by military operations of containment by isolating and killing populations of infected territories under pretexts of religious and/or ethnic cleansing.
Corollary A: The several existing conditions such as war, famine, and weather contributed to the severity of the Black Death. Most of the victims of plagues were due to Black Death military operations and not to the disease proper. Moreover, they became one of the prime movers of the disintegration of Evil Empire.
Corollary C: Epidemics of syphilis, plague, pox, and cholera have played a major role in the civilization of the homo sapience species. This is ignored by the adepts of consensual history due to the erroneous chronology of Scaliger and Petavious it is based upon.
