Mexico City's Templo Mayor was built by the ____s (5)

I believe the answer is:

aztec

(Other definitions for aztec that I've seen before include "Montezuma ruled this empire" , "Member of ancient Mexican tribe" , "Pre-conquest Mexican Indian" , "one of the old people" , "Ancient inhabitant of Mexico before Spanish conquest" .)

I've seen this clue in The Times.
