How did climate change and disease impact the fall of Rome?

Modern scholarship attributes part of the decline of the Western Roman Empire to environmental factors such as climate shifts and epidemic or endemic diseases. These pressures drove population health declines and mass migrations that strained Roman administrative and military capabilities. Historians continue to debate the relative weight of these external and internal pressures compared to traditional political explanations.

What we know

• Modern scholarship has introduced climate change, epidemic diseases, and environmental degradation as important reasons for the decline of the Roman Empire. [2]
• Climatic changes and both endemic and epidemic diseases drove many of the immediate factors behind the loss of central political control in the Western Roman Empire. [4]
• In 376, a large migration of Goths and other non-Roman people fled from the Huns and entered the Empire, partly reshaping external pressures. [4]

Still open

• Historians differ on whether the decline was a true collapse or a gradual transformation into medieval societies, and whether internal or external factors were most decisive.
