In terms of metal working, yeah, but that's not the only way to measure a culture.
As mentioned, they built a city that was larger then almost anything in europe or asia at the time WITH ONLY that level of metal working and without having any sort of horses, oxen, or other pack/work animals. It outright had superior hydoenginnering and agricultural techniques as well. If the aztecs were so primitive, then how come they rivaled europe with imfeiror technology in those regards? Wouldn't that mean that Europeans and asians were just shitters?
They were behind in some ways and ahead in others, which, you know, makes sense considering they were on an isolated continent and all.
Anyways, I agree the Kongo don't deserve the spot. If they wanted an african civ other then egypt, they should have gone for the Mali. I don't see why brazil doesn't deserve it but something like Poland or indivual european nations do.
The only other cities that surpassed or rivaled Tenochtitlan at the time were Cairo, Bejing, Constantinople, Paris, and some place in india I don't recall the name of.
Because they meet the technical defition of an empire and accomplished noteworthy feats? Also, stacking stones? Are you seriously this stupid or are you a delusional Holla Forumsfag?
This is from chapters LXXXVII and XCII of the True History of the Conquest of the New Spain.
The Incans deserve the spot as well. They had similarly impressive architectural feats and controlled a proper empire and a large amount of territory. The Maya are tricky in that they were never unified, they were just a collection of city states that shared a rough culture, and even that that was iffy and had subdiscisons.
I don't think the Maya are a worse choice then a lot of other civs they've picked, but if you wanna be technical then they wouldn't qualify
