The Benty Grange helmet is an Anglo-Saxon boar-crested helmet from the 7th century AD. It was excavated by Thomas Bateman in 1848 from a tumulus at the Benty Grange farm in Monyash in western Derbyshire. The grave had probably been looted by the time of Bateman's excavation, but still contained other high-status objects suggestive of a richly furnished burial, such as the fragmentary remains of a hanging bowl. The helmet is displayed at Sheffield's Weston Park Museum, which purchased it from Bateman's estate in 1893.

The helmet was constructed by covering the outside of an iron framework with plates of horn and the inside with cloth or leather; the organic material has since decayed. It would have provided some protection against weapons, but was also ornate and may have been intended for ceremonial use. It was the first Anglo-Saxon helmet to be discovered, with five others found since: Sutton Hoo (1939), Coppergate (1982), Wollaston (1997), Shorwell (2004) and Staffordshire (2009). The helmet features a unique combination of structural and technical attributes, but contemporaneous parallels exist for its individual characteristics. It is classified as one of the "crested helmets" used in Northern Europe from the 6th to 11th centuries AD.

The most striking feature of the helmet is the boar at its apex; this pagan symbol faces towards a Christian cross on the nasal in a display of syncretism. This is representative of 7th-century England when Christian missionaries were slowly converting Anglo-Saxons away from traditional Germanic paganism. The helmet seems to exhibit a stronger preference toward paganism, with a large boar and a small cross. The cross may have been added for talismanic effect, the help of any god being welcome on the battlefield. The boar atop the crest was likewise associated with protection and suggests a time when boar-crested helmets may have been common, as do the helmet from Wollaston and the Guilden Morden boar. The contemporary epic Beowulf mentions such helmets five times and speaks of the strength of men "when the hefted sword, its hammered edge and gleaming blade slathered in blood, razes the sturdy boar-ridge off a helmet".

The Anglo-Saxons were a cultural group who inhabited England in the Early Middle Ages. They traced their origins to settlers who came to Britain from mainland Europe in the 5th century. However, the ethnogenesis of the Anglo-Saxons happened within Britain, and the identity was not merely imported. Anglo-Saxon identity arose from interaction between incoming groups from several Germanic tribes, both amongst themselves, and with indigenous Britons. Many of the natives, over time, adopted Anglo-Saxon culture and language and were assimilated. The Anglo-Saxons established the concept, and the Kingdom, of England, and though the modern English language owes somewhat less than 26% of its words to their language, this includes the vast majority of words used in everyday speech.Historically, the Anglo-Saxon period denotes the period in Britain between about 450 and 1066, after their initial settlement and up until the Norman Conquest.

The early Anglo-Saxon period includes the creation of an English nation, with many of the aspects that survive today, including regional government of shires and hundreds. During this period, Christianity was established and there was a flowering of literature and language. Charters and law were also established. The term Anglo-Saxon is popularly used for the language that was spoken and written by the Anglo-Saxons in England and southeastern Scotland from at least the mid-5th century until the mid-12th century. In scholarly use, it is more commonly called Old English.The history of the Anglo-Saxons is the history of a cultural identity. It developed from divergent groups in association with the people's adoption of Christianity and was integral to the founding of various kingdoms. Threatened by extended Danish Viking invasions and military occupation of eastern England, this identity was re-established; it dominated until after the Norman Conquest. Anglo-Saxon material culture can still be seen in architecture, dress styles, illuminated texts, metalwork and other art. Behind the symbolic nature of these cultural emblems, there are strong elements of tribal and lordship ties. The elite declared themselves kings who developed burhs, and identified their roles and peoples in Biblical terms. Above all, as Helena Hamerow has observed, "local and extended kin groups remained...the essential unit of production throughout the Anglo-Saxon period." The effects persist, as a 2015 study found the genetic makeup of British populations today shows divisions of the tribal political units of the early Anglo-Saxon period.The term Anglo-Saxon began to be used in the 8th century (in Latin and on the continent) to distinguish "Germanic" groups in Britain from those on the continent (Old Saxony and

Anglia in Northern Germany). Catherine Hills summarised the views of many modern scholars in her observation that attitudes towards Anglo-Saxons, and hence the interpretation of their culture and history, have been "more contingent on contemporary political and religious theology as on any kind of evidence."
