History Shorts: Justinian's Plague (541-542)

Justinian reconquered the Western Roman Empire and Europe seemed assured of escaping the Dark Ages. In 541, a pandemic struck the globe unraveling Justinian’s conquests. The plague seems to have originated in China and moved westward killing 25 million. Constantinople was especially hard hit. The disease wiped out 40% of the populace. Research indicates the plague was not the same disease that ravaged Europe in the 14^th century. The plague might have been brought forth by cold, damp weather following a massive volcanic eruption. In the end, the disease decimated the Byzantine Empire and its ability to hold onto Western Europe. As a result, Europe entered the Dark Ages.
