History often celebrates inventions, empires and revolutions. Yet disease has shaped societies just as profoundly.
Beyond the best-known outbreaks, historians are increasingly studying lesser-known pandemics and epidemics that altered populations, labour systems and political decisions.
These crises influenced migration, weakened armies, transformed cities and accelerated changes in public health long before modern medicine emerged.
The Black Death remains the most famous example, but later influenza waves, cholera outbreaks and regional epidemics also left deep marks on economic and social development.
In many cases, disease exposed inequality. Poorer communities often suffered higher mortality and had fewer resources for recovery.
Researchers say these histories matter because they challenge simplistic ideas of steady human progress.
Advancement has often come alongside vulnerability, and societies have repeatedly been reshaped by biological forces beyond their control.
Understanding forgotten pandemics helps place modern health crises in a longer historical perspective.
