How Did the Plague of Justinian Change History

The Plague of Justinian (541–542 CE) was one of the worst plagues in recorded history, arguably bringing two major empires to devastation and affecting numerous societies across Eurasia. The only other known event comparable to its impact was the Black Death of the 14th century. These two plagues are perhaps even related, as both seem to start in Central Asia and are based on the plague carried by rats.
