I’d like to develop a list of the “Great Theories of History,” and I could use your help!

If you know of such a Theory, could you kindly send me its name, its book title, and its author?

Here are a few that I’ve come up with:

“Challenge and Response” — Arnold Toynbee

“Guns, Germs, and Steel” — Jared Diamond

“Class Struggle” (Das Kapital) — Karl Marx

“Cognition, Agriculture, Science, Globalism (the “Sapiens” books) — Yuval Harari
