Despite not being in central America there is a lot of similar motifs between the Aztec and Mississippian culture. Aztec culture was 1300 to early 1500s. Mississippian was from 800 to 1600. All of Aztec culture fits inside the end of Mississippiian.
I wish we had a better understanding of trade routes throughout different periods of pre Columbian America.
Mississippian culture:
Hmm the Aztec story is that they walked south following their leader for a long time. Then when they found an eagle perched on a prickly pear in the middle of a lake, that was the sign. They stopped there, named it tenochtitlan and yada yada yada Spanish, yada yada yada Chinese silk road yada yada, Mexico, south America, the Philippines, more yada yada, 13 colonies, the USA.
They did a lot of yada yada back then.
