Most of Human History is focused on Eurasia and Alternate History mostly follows suit. Africa, outside of the Northern region, only gets mentioned when it comes to slavery or colonization. The Indigenous Americans and Aboriginal Australians are generally seen as tribes to get conquered and little else.
Is there any story where Native Americans or Sub-Saharan Africans or Aboriginal Australians end up building a big civilization and industrializing?
Mask of the Sun, and its sequel anthology,
Golden Reflections.
Basically the setting is an infinite multiverse of human histories in which two powers have arisen to contest the whole thing: the Aztecs and the Inca.
Somewhere, in one timeline of many, the Aztecs achieved world domination. In another, the Inca did. Now, they're each trying to flip as many timelines as possible to their side by fucking over each others' development there. This means they can go between timelines as well as back and forth inside them, which I've never seen before in any such fiction; usually it's either back-and-forth (Cross-Time by Poul Anderson, sorta) or side-to-side (Kalvan / Paratime Police, by H. Beam Piper).
There are multiple stories within each book, and they're all told from the perspective of a hapless local who falls into the schemes of one or another group.
Throughout the stories, the Inca are generally the good guys, but I personally think he makes them out to be just a bit too... nice? palatable? I don't know how to put it, but some versions of the Inca are a bit beyond the pale.
(I mean, constitutional monarchy? Mate, you serious?) Either way, we get to see the Aztecs in full play, and they're not nice fellows.
If you want to see what happens when religious cannibalism is an accepted practice, try imagining what happens when you're a spy who gets caught and, uh,
interrogated by them.
