This is a little off-topic, but does anyone know of any TLs where all of Eurasia is wiped out by the *plague? This would leave sub-Saharan Africa, the Americas, and Oceania as the only hosts of civilization left.

Any help would be appreciated.

I don't know of any, but I think it's and interesting idea. Maybe we can discuss one here. So, what if Eurasia and North Africa had been wiped out by a plag as in The years of Rice and Salt???

Or, if you think it's too ASB, what if a sort of fungus or deadly plant disease had attacked the cereales which were the base of the diet of the people throughout Eurasia during the XV century (wheat, barley and rice)? Let's say this fungus or disease never reaches the Americas (due to the Ocean), Ocenia (for the same reasons) and Subsaharan Africa due to the Sahara.

Let's say Eurasian Populations drops 95% or more, and that survivors are unable to grow any cereal crops, and are forced to become huntergatherers, fishers or herders (which would keep their numbers low), until American crops are introduced.

Which civilization would eventually dominate: the american ones, African ones, or a Polynesian-based one? Which group would develop faster and get in touch with the others first???
