The Black Death
The Black Death was one of the most devastating global pandemics that the world has ever seen. The outbreak was believed to have been started in central Asia in the 14th century, and then was spread to Europe through the merchant ships. After reaching Europe, it took absolutely no time for the disease to kill almost 30 to 60 percent of Europe's population. It was so brutal and deadly that if a person was infected by it in the morning, he could be dead by the end of the day.
