Aztec Massacre is a 2008 television documentary produced by Thirteen/WNET New York and ITVS International and broadcast as part of PBS's Secrets of the Dead series. It presents the grisly discovery of more than 400 mutilated skeletons at the Aztec site of Zultapec, Mexico. It purports to show that the 500 year old discovery “paints a new picture of the violent relations between the Aztecs and the Conquistadors and rewrites much of what we thought we knew about the Aztec civilization”.
