Potato blight (Phytophthora infestans) destroys several successive potato harvests, the near-sole food of a third of the population, while the island keeps exporting grain and livestock to England.

Consequences

Human consequences

The population falls from 8.2 million (1841) to 6.6 million (1851); more than a million Irish people emigrate, mainly to North America.

Environmental consequences

Reliance on a single potato variety, the “Lumper”, leaves the entire crop vulnerable to the pathogen.

Economic consequences

Smallholders disappear and land becomes concentrated.

Political consequences

Lasting resentment towards London fuels Irish nationalism until independence.
