Tambora

THE EMPIRE WAS NOT ROME. IT WAS THE WEATHER.

The year 1816 was the coldest summer in two millennia. Snow fell in New England in June. Lakes froze in Pennsylvania in July. Across Europe, endless rain brought famine, riots, and total despair. The world didn't know it, but civilization had been hijacked by a mountain on the other side of the planet.
This is the untold, minute-by-minute true story of the 1815 Mount Tambora volcanic eruption, and how its deadly fallout changed global history.

• THE AMERICAN CRISIS: How the "Poverty Year" destroyed American farming and fueled the mass westward migration that defined the 19th century.
• THE EUROPEAN COLLAPSE: The famines, typhus epidemics, and bread riots that brought war-weary nations to their knees and reshaped the continent's political future.
• THE BIRTH OF HORROR: Why Mary Shelley was trapped inside on a freezing Swiss lake in July, and the terrifying gothic novel she wrote as a direct result of the volcanic gloom.
• THE PLAGUE EFFECT: How the collapse of the Indian monsoon triggered the birth of a *new, virulent cholera strain* that would kill millions worldwide in the decades to follow.

If you want to understand the fragility of human civilization when confronted with climate change and global catastrophe, you must read the definitive account of 1816.
