5. the maya did not unite to form a single united empire. independent city-states or kingdoms with common cultural ties developed instead. what cultural elements did these city-states share?

1) language, including the script - the Mayan language and the script (the only in the new world!) were shared among the city-states

2) science - calendar (and its religious interpretation) mathematics and astronomy

3) art and architecture - despite being separate states, the remains from different city-states are very similar and the architecture and the art form is shared.
