Arabs supply more guns to Africa, so they later form larger power blocs to resist European encroachments a little more effectively.
Vikings in N. America go further south and spread smallpox more and the native Americans develop a little more immunity earlier
pandemics which occur later, are less severe
more competent Byzantine Emperor strengthens empire a little more.
Ottoman civil war limits Ottoman expansion, fewer competent rulers limit its influence.
Fall of Constantinople happens two centuries later.
Since the Byzantine empire survives longer trade routes to the east open remain open longer, so there is more incentive to explore east not west across the Atlantic.
The first effort to sail west across the Atlantic fails, the ships sink.
Successful attempts to cross Atlantic delayed.
Chinese explorers to Africa bring back an African pandemic
Chinese civilization collapses long enough for Thailand to expand northward.
A group in S. China, the Zhuang, who are related to the Thai, fill the power vacuum.
European influence in East Asia much greater.
Contact with Japan and Polynesians much earlier, and the Polynesians, influenced by Europeans, discover America first by landing in California.
In this timeline the main power blocs are Hawaii Australia Thailand Armenia, and France. At least any two African groups and two Native American groups would be significant, but which ones might be rather random.
Citing the Incas, Aztecs and Mayans seems a bit cliched and obvious.
I suppose the main reason to bring in Thailand is to have somebody other than China as a major power, which seems overly familiar.
Could Constantinople survive as a microstate? After all, we have the Vatican Monaco Andorra and others.
