Totenkopf

Totenkopf is a German compound word for death's head. The word is often used to denote a figurative, graphic or sculptural symbol, common in Western culture, consisting of the representation of a human skull – usually frontal, more rarely in profile with or without the mandible. In some cases, other human skeletal parts may be added, often including two crossed long bones depicted below or behind the skull. The human skull is an internationally used symbol for death, the defiance of death, danger, or the dead, as well as piracy or toxicity.
In English, the term Totenkopf is commonly associated with 19th- and 20th-century German militarism, particularly in Nazi Germany.
The German word for skull, used in medical and other contexts, is Schädel; it lacks all military and other associations.

Naval use

In early modern sea warfare to early modern sea piracy, buccaneers and pirates used the Totenkopf as a pirate flag: a skull or other skeletal parts as a death threat and as a demand to hand over a ship. The symbol continues to be used by modern navies.

German military

Prussia

Use of the Totenkopf in Germany as a military emblem began under Frederick the Great, who formed a regiment of Hussar cavalry in the Prussian army commanded by Colonel von Ruesch, the Husaren-Regiment Nr. 5. It adopted a black uniform with a Totenkopf emblazoned on the front of its mirlitons and wore it on the field in the War of Austrian Succession and in the Seven Years' War. The Totenkopf remained a part of the uniform when the regiment was reformed into Leib-Husaren Regiments Nr.1 and Nr.2 in 1808. The symbol was then granted 3 years later to the Spanish Army’s 8th Light Cavalry Regiment “Lusitania”, who were nicknamed “Los Dragones de la Muerte” and were granted use of the skull after the infamous Battle of Madonna dell'Olmo in 1744, where they suffered great casualties.

Brunswick

In 1809, during the War of the Fifth Coalition, Frederick William, Duke of Brunswick-Wolfenbüttel raised a force of volunteers to fight Napoleon Bonaparte, who had conquered the Duke's lands. The Brunswick corps was provided with black uniforms, giving rise to their nickname, the Black Brunswickers. Both hussar cavalry and infantry in the force wore a Totenkopf badge, either in mourning for the duke's father, Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel, who had been killed at the Battle of Jena–Auerstedt in 1806, or according to some sources, as a sign of revenge against the French. After fighting their way through Germany, the Black Brunswickers entered British service and fought with them in the Peninsular War and at the Battle of Waterloo. The Brunswick corps was eventually incorporated into the Prussian Army in 1866.

German Empire

The skull continued to be used by the Prussian and Brunswick armed forces until 1918, and some of the stormtroopers that led the last German offensives on the Western Front in 1918 used skull badges. Luftstreitkräfte fighter pilots Georg von Hantelmann and Kurt Adolf Monnington are just two of a number of Central Powers military pilots who used the Totenkopf as their personal aircraft insignia.

Weimar Republic

The Totenkopf was used in Germany throughout the interwar period, most prominently by the Freikorps. In 1933, it was in use by the regimental staff and the 1st, 5th, and 11th squadrons of the Reichswehrs 5th Cavalry Regiment as a continuation of a tradition from the Kaiserreich.

Nazi Germany

In the early days of the Nazi Party, Julius Schreck, the leader of the 1st [SS Division Leibstandarte SS Adolf Hitler|Stabswache], resurrected the use of the Totenkopf as the unit's insignia. This unit grew into the Schutzstaffel, which continued to use the Totenkopf as insignia throughout its history. According to a writing by Reichsführer-SS Heinrich Himmler, the Totenkopf had the following meaning:

The Skull is the reminder that you shall always be willing to put your self at stake for the life of the whole community.

SS-Totenkopfverbände was the Schutzstaffel organization responsible for administering the Nazi concentration camps and extermination camps for Nazi Germany, among similar duties. While the Totenkopf was the universal cap badge of the SS, the SS-TV also wore this insignia on the right collar tab to distinguish itself from other SS formations.
The Totenkopf was also used as the unit insignia of the Panzer forces of the German Heer, and also by the Panzer units of the Luftwaffe, including those of the elite Fallschirm-Panzer Division 1 Hermann Göring.
Both the 3rd SS Panzer Division of the Waffen-SS, and the World War II era Luftwaffe's 54th Bomber Wing Kampfgeschwader 54 were given the unit name "Totenkopf", and used a strikingly similar-looking graphic skull-crossbones insignia as the SS units of the same name. The 3rd SS Panzer Division also had skull patches on their uniform collars instead of the SS sieg rune.

As the phrase also has innocuous meanings, its use by neo-Nazis is an example of a dogwhistle that relies on plausible deniability.

Etymology

Toten-Kopf translates literally to "Dead 's Head", meaning exactly "dead person's head". Semantically, it refers to a skull, which in German is a Schädel. As a term, Totenkopf connotes the human skull as a symbol, typically one with crossed thigh bones as part of a grouping.
While earlier German may have used Totenkopf in its more literal sense wrote in the story "Baron Hüpfenstich": "Lauter Totenbeine und Totenköpfe, die standen oben herum...", it is unclear whether there are similar instances in contemporary German, given the more widespread word for 'skull' and the ineluctable connotations of Totenkopf.
