Marduk are a black metal band from Norrköping, Sweden. The name is derived from the Babylonian name of a late-generation god from ancient Mesopotamia, Marduk, patron deity of Babylon. Marduk's predominant lyrical topics are Satanism, anti-Christianity, Biblical tales, Third Reich history and World War II. The latter two are a later addition to their lyrical / conceptual themes, stemming from their 1999 release Panzer Division Marduk; quickly growing among their fans' favorites. Marduk have released more and more songs relating to those chapters of human history, such as "The Hangman of Prague" (moniker of Prague "Reichsprotektor" Reinhard Heydrich), "Night of the Long Knives", "Deathmarch" and others. It has to be noted, however, that by singing about Nazi Germany, Marduk do not subscribe to the tenets of the "national socialist black metal" scene (see NSBM), their approach not being justificatory or praising.   Wikipedia
