Moctezuma station is named after the neighborhood in which it is found, itself named after the 2nd to last Aztec emperor, Moctezuma II or Moctezuma Xocoyotzin (Moctezuma the younger). He was the Aztec leader that was taken as a hostage during Hernán Cortés’ campaign against the Aztecs in 1520, and he died later that year, possibly by stones thrown by his countrymen, or possibly killed by the Spaniards.
The icon of the station represents the feathered headdress which supposedly was worn by Moctezuma, which is now found in a museum in Vienna, Austria. There is a reproduction of this headdress in the wonderful Anthropology museum in Mexico City, found near Auditorio metro.
