A '''skull and crossbones''' is a [[symbol]] consisting of a [[human skull]] and two [[long bone]]s crossed together under or behind the skull.<ref name="Merriam-webster">{{Cite web|url=https://www.merriam-webster.com/dictionary/skull%20and%20crossbones|title=Dictionary and Thesaurus|website=Merriam-webster.com}}</ref> The design originated in the [[Late Middle Ages]] as a symbol of [[death]] and especially as a ''[[memento mori]]'' on tombstones. Actual skulls and bones were long used to mark the entrances to [[Skull and crossbones (Spanish cemetery)|Spanish cemeteries (campo santo)]].

In modern contexts, it is generally used as a [[hazard symbol]], usually in regard to [[poison]]ous substances, such as deadly chemicals.<ref name="Merriam-webster"/>

It is also associated with [[piracy]] and [[software piracy]], due to its historical use in some [[Jolly Roger]] flags.

== Military use ==
{{main article|Skull and crossbones (military)}}
The skull and bones are often used in military insignia, such as the [[coats of arms]] of [[regiment]]s.<ref>{{Cite web|url=https://www.army.mod.uk/who-we-are/corps-regiments-and-units/royal-armoured-corps/royal-lancers/|title=WEARING THE SKULL AND CROSSBONES WITH PRIDE|website=The British Army}}</ref><ref>{{Cite book|title=The German Army in World War I (1): 1914–15|last=Thomas|first=Nigel|publisher=Bloomsbury Publishing|year=2012|isbn=9781780965512}}</ref><ref>{{Cite book|title=Colburn's United Service Magazine and Naval and Military Journal, Volumen 32|publisher=National Library of the Netherlands|year=1867|pages=321}}</ref><ref>{{Cite book|title=Death's Head - Volumen 1 de The History of Uniform|last=Hølscher|first=Joost|publisher=Editions Chamerelle|year=2013|isbn=9789082032604|pages=33}}</ref><ref>Joost Hølscher (Author, Illustrator): Death's Head, The History of the Military Skull & Crossbones Badge (The History of Uniform). 1st edition: Éditions Chamerelle 2013, {{ISBN|978-90-820326-0-4}}.</ref>

Since the mid-18th century, skull and crossbones insignia has been officially used in European armies as symbols of superiority. One of the first regiments was the [[Frederick the Great]]'s Hussars in 1741, also known as the "{{lang|de|Totenkopfhusaren}}". From this tradition, the skull became an important emblem in the German army. Identical insignia has been used in the Prussian army after the First World War by {{lang|de|[[Freikorps]]}} and in Nazi Germany by the [[Wehrmacht]] and the [[SS]]. The idea of elitism symbolized by the skull and crossbones has influenced sub- and pop culture and has become part of the fashion industry.<ref>{{Cite book|title=Der Totenkopf als Motiv.

The skull and crossbones has long been a standard symbol for [[poison]].

In 1829, [[New York State]] required the labeling of all containers of poisonous substances.<ref>{{cite book|url=https://books.google.com/books?id=N4N9bsxc2LYC&q=skull+and+crossbones+symbol+of+poison&pg=PA92|title=History of Drug Containers and Their Labels|first1=George B.|last1=Griffenhagen|first2=Mary|last2=Bogard|date=19 November 1999|publisher=Amer. Inst. History of Pharmacy|isbn=9780931292262|access-date=19 November 2017|via=Google Books}}</ref> The skull and crossbones symbol appears to have been used for that purpose since the 1850s. Previously a variety of motifs had been used, including the [[Denmark|Danish]] "+ + +" and drawings of [[skeleton]]s.<ref>{{cite magazine |title=Antique Poison Bottles |url=https://www.collectorsweekly.com/bottles/poison-bottles |magazine=Collectors Weekly |access-date=26 February 2022}}</ref>

In the 1870s poison manufacturers around the world began using bright [[Cobalt glass|cobalt]] bottles with a variety of raised bumps and designs (to enable easy recognition in the dark) to indicate poison,<ref>{{cite web |title=Poison bottle collection | series=Antiques Roadshow |url=https://www.bbc.co.uk/programmes/articles/2CJMhJnJW8lkGZ4S61fVvGf/poison-bottle-collection |publisher=BBC One |access-date=26 February 2022}}</ref> but by the 1880s the skull and cross bones had become ubiquitous, and the brightly coloured bottles lost their association.<ref name=Farmer>{{cite web |title=Evolution of the Poison Label: From Skull and Crossbones to Mr. Yuk |url=https://designresearch.sva.edu/research/evolution-of-the-poison-label-from-skull-and-crossbones-to-mr-yuk/ |first=Meg |last=Farmer |website=SVA.edu | date=March 2014 |access-date=26 February 2022}}</ref>

In the United States, due to concerns that the skull-and-crossbones symbol's association with [[pirates]] might encourage children to play with toxic materials, the [[Mr. Yuk]] symbol was created to denote poison. However, in 2001, the American Association of Poison Control Center voted to continue to require the skull and crossbones symbol.<ref name=Farmer />
