This video is a history teaching material and looking back on Worldwide Medieval Plague Epidemic and the background.
As many learned in the school history, it was really tragic and catastrophic.
Yet one more important point of view might not taught there.
That's the WAR.
On the background of war made the plague epidemic serious more, with the scarcity of supplies and food, the destruction of living infrastructure, and the paralysis of social functions.
This historical fact was repeated in 1918 during World War I with Spanish flu.
Then now we are facing Corona pandemic, and in parallel the Spratly Islands, Taiwan conflict, and Ukraine crisis are on going, the situation might be clashing anytime soon.
This reality cannot be ignored for the epidemic gets much more dangerous.
War kills more by the plague and famine than by the combat on battle fields.
In case of Imperial Japanese Army and Navy in World War II, two-thirds of the total death was not caused in battle, but they died for illness and starvation due to the harsh environment.
