Sigmund is a German name derived from the Germanic elements "sigi" meaning victory and "mund" meaning protection, signifying "protected by victory". It was popular among medieval Teutonic knights and carried by notable figures like Sigurd Sigmundsson. In literature, Sigmund is known as Siegfried's father in Wagner's opera cycle, "The Ring Cycle", and in Norse mythology, he was a legendary hero and king of the Volsungs. Today, it remains relatively uncommon outside Germany and Scandinavia but carries historical significance and powerful meaning associated with strength, courage, and triumph over adversity. Although originally masculine, Sigmund has also been used as a female given name in some instances.
