The Inca Empire was one of the largest and most successful of the empires of the Americas, being part of the "Big Three" which most people are familiar with. It started out as a small city-state in the Cusco Valley, that grew to encompass much of the region under the reign of Pachacuti(1438-1471), and later on under his successors. It is still debated whether the Inca expansion was the result of one political and military genius, or a culmination of social, political, and economic factors that culminated into the inevitability of large-scale conquest by a central Andean power. The question I would like to ask is, what if another Andean state, perhaps the Chimu, or one of the Aimara principalities, achieved a similar expansion and united the region under it's banner? How would it's culture and technology differ? How would the history of the Andes be changed? How would it react to the Spanish? And how would a culture and language which is formerly hegemonic over an empire fare under the Spaniards if conquest still happens as OTL? Which polities are most likely to do this?
