"This trend of higher food prices leading to social unrest extends far back into history and surrounds many key turning points. The French Revolution of 1789, which overthrew the Ancien Régime, came after a succession of poor harvests that led to major rises in food prices"

It was a similar story at the time of Europe’s 1848 revolutions too, which followed the failure of potato crops in the 1840s and the associated severe famine in much of Europe. And the 1917 overthrow of the Tsarist regime in Russia took place in the context of food shortages as well."
