What was going on in America during the time of the Renaissance?

During the Renaissance in Europe, the Aztec Empire in Mexico was building a city that was far grander than any city in Europe.

On the other hand, the Maya culture was collapsing. When the Spanish arrived, Maya cities had vanished. People could still read the Mayan syllables. Maya writing has been cracked. A new Mayan syllabary has been created. A Catholic priest had made a copy of a Mayan text and the Spanish equivalent.

In South America the Inca Empire was absorbing the surrounding cultures. It created a form of writing using beads. No one has ever figured out how it worked. The Incas invented the suspension bridge.
