Reddit reviews Global Crisis: War, Climate Change and Catastrophe in the Seventeenth Century

I would recommend reading Global Crisis: War, Climate Change and Catastrophe in the Seventeenth Century. Basically, the Celali Rebellions, fall of the ming, and a host of uprisings across the old world from Catalonia to China were caused in part by food shortages from the eruption of a super volcano. Economic downturn in one area of a country caused recessions in neighboring provinces which caused massive famines. Combined with warfare and government mismanagement in many countries revolts were frequent during this time. The best solution is to better simulate local economies and make a economic policy system that simulates how religions, customs or bad management by rulers inform economic policies on the local level.
