Final answer:
The Great Famine of 1315–1317 resulted in the death of approximately 10 percent of Northern Europe's population, due to the effects of the Little Ice Age and subsequent food shortages.
Step-by-step explanation:
During the Great Famine of 1315–1317, caused by the climate changes of the Little Ice Age, up to 10 percent of Northern Europe's population perished.
This catastrophic event happened when Northern Europe had over thirty million inhabitants, resulting in a devastating population decline. Due to food shortages, prices for essentials like grain soared, leading to increased social unrest and a downturn in public trust towards institutions like the monarchy and church.
