The European badger is a powerfully built, black, white, brown, and grey animal with a small head, a stocky body, small black eyes, and a short tail. Its weight varies, being 7–13&nbsp;kg (15–29&nbsp;lb) in spring, but building up to 15–17&nbsp;kg (33–37&nbsp;lb) in autumn before the [[winter sleep]] period. It is [[Nocturnality|nocturnal]] and is a [[Sociality|social]], burrowing animal that sleeps during the day in one of several [[sett]]s in its territorial range. These burrows have multiple chambers and entrances, and are extensive systems of underground passages of {{convert|35|-|81|m|abbr=on}} length. They house several badger families that use these setts for decades. Badgers are fussy over the cleanliness of their burrow, carrying in fresh bedding and removing soiled material, and they defecate in [[Latrine (animal)|latrine]]s strategically situated outside their setts or en route to other setts.<ref name ="Kilshaw">{{cite journal | vauthors=Kilshaw K, Newman C, Buesching CD, Bunyan J, Macdonald DW | title=Coordinated latrine use by European badgers, Meles meles: Potential consequences for territory defense | journal=Journal of Mammalogy | volume=90 | issue=5 | date=2009 | pages=1188–1198 | doi=10.1644/08-MAMM-A-200.1 | jstor=27755113 | s2cid=86435009 | doi-access=free }}</ref>
 
Although classified as a [[carnivore]], the European badger is an [[omnivore]], feeding on a wide variety of plant and animal foods, including [[earthworm]]s, large [[insect]]s, small [[mammal]]s, [[carrion]], [[cereals]], and [[tuber]]s. Litters of up to five cubs are produced in spring. The young are weaned a few months later, but usually remain within the family group. The European badger has been known to share its burrow with other species, such as [[rabbit]]s, [[red fox]]es, and [[raccoon dog]]s, but it can be ferocious when provoked, a trait which has been exploited in the now-illegal [[blood sport]] of [[badger-baiting]].

==Distribution and habitat==
The European badger is native to most of Europe. Its range includes Albania, Armenia, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Crete, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Georgia, Germany, Great Britain, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Macedonia, Moldova, Montenegro, Netherlands, Norway, Poland, Portugal, Romania, Russia, Kosovo, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland and Ukraine.<ref name=iucn />
 
The distributional boundary between the ranges of European and [[Asian badger]]s is the [[Volga River]], the European species being situated on the western bank.<ref name=":0" /> The boundary between the ranges of the European and [[Caucasian badger]]s is in the [[North Caucasus]], but a clear boundary has not been defined, and they are [[Sympatry|sympatric]] in some regions, potentially forming a [[hybrid zone]].<ref>{{Cite journal |last1=Abramov |first1=A.

European badgers are the most social of badgers,<ref name="m117"/> forming groups of six adults on average, though larger associations of up to 23 individuals have been recorded. Group size may be related to habitat composition. Under optimal conditions, badger [[Territory (animal)|territories]] can be as small as {{cvt|30|ha}}, but may be as large as {{cvt|150|ha}} in marginal areas.<ref name="h430"/> Badger territories can be identified by the presence of communal [[latrine]]s and well-worn paths.<ref>{{cite journal |author1=Schmid, T.

A hierarchical social system is thought to exist among badgers and large powerful boars seem to assert dominance over smaller males.

Badgers are vulnerable to the mustelid [[herpesvirus]]-1, as well as [[rabies]] and [[canine distemper]], though the latter two are absent in Great Britain.

They also suffer from mange.<ref name="h435"/> They spend much time grooming, individuals concentrating on their own ventral areas, alternating one side with the other, while social grooming occurs with one individual grooming another on its dorsal surface. Fleas tried to avoid the scratching, retreating rapidly downwards and backwards through the fur. This was in contrast to fleas away from their host, which ran upwards and jumped when disturbed. The grooming seems to disadvantage fleas rather than merely having a social function.<ref>{{cite journal |author1=Stewart, Paul D. |author2=Macdonald, David W. |year=2003 |title=Badgers and Badger Fleas: Strategies and Counter-Strategies |journal=Ethology |volume=109 |issue=9 |pages=751–763 |doi=10.1046/j.1439-0310.2003.00910.x |bibcode=2003Ethol.109..751S }}</ref>

{{main|List of fictional badgers}}
Badgers play a part in European folklore and are featured in modern literature. In [[Irish mythology]], badgers are portrayed as [[therianthropyShapeshifting|shape-shifter]]s and kinsmen to Tadg, the king of [[Hill of Tara|Tara]] and foster father of [[Cormac mac Airt]]. In one story, Tadg berates his adopted son for having killed and prepared some badgers for dinner.<ref>Monaghan, Patricia, ''The encyclopedia of Celtic mythology and folklore'', p.436, Infobase Publishing, 2004, {{ISBN|0-8160-4524-0}}</ref> In [[German folklore]], the badger is portrayed as a cautious, peace-loving [[Philistinism|Philistine]], who loves more than anything his home, family and comfort, though he can become aggressive if surprised. He is a cousin of [[Reynard the Fox]], whom he uselessly tries to convince to return to the path of righteousness.<ref name="n150"/>
 
In [[Kenneth Grahame]]'s ''[[The Wind in the Willows]]'', Mr. Badger is depicted as a gruff, solitary figure who "simply hates society", yet is a good friend to Mole and Ratty. As a friend of Toad's now-deceased father, he is often firm and serious with Toad, but at the same time generally patient and well-meaning towards him. He can be seen as a wise hermit, a good leader and gentleman, embodying common sense. He is also brave and a skilled fighter, and helps rid Toad Hall of invaders from the wild wood.<ref>{{cite book |title=The Wind in the Willows |last=Grahame |first=Kenneth |year=1908 |publisher=Wordsworth Editions Ltd. |isbn=978-1853260179 }}</ref>
