The period of Anglo-Saxon Warfare spans the 5th Century AD to the 11th in England. Its technology and tactics resemble those of other European cultural areas of the Early Middle Ages, although the Anglo-Saxons, unlike the Continental Germanic tribes such as the Franks and the Goths, do not appear to have regularly fought on horseback.
Although much archaeological evidence for Anglo-Saxon weaponry exists from the Early Anglo-Saxon period due to the widespread inclusion of weapons as grave goods in inhumation burials, scholarly knowledge of warfare itself relies far more on the literary evidence, which was only being produced in the Christian context of the Late Anglo-Saxon period.
These literary sources are almost all authored by Christian clergy, and thus do not deal specifically with warfare; for instance, Bede's Ecclesiastical History of the English People mentions various battles that had taken place but does not dwell on them. Thus, scholars have often drawn from the literary sources from neighbouring societies, such as those produced by continental Germanic societies like the Franks and Goths, or later Viking sources.
As Underwood noted, "Warfare in the Anglo-Saxon period cannot be viewed as a uniform whole". This is because Anglo-Saxon society changed greatly during this period; in the fifth century, it constituted an array of small tribal groups while by the eleventh it had consolidated into a single state.
There are extant contemporary descriptions of some Anglo-Saxon battles. Of particular relevance are the poems recounting the battles of Brunanburh, fought in 937 AD and Maldon, fought in 991 AD. In the literature, most of the references to weapons and fighting concern the use of javelins, and swords, with only occasional references to archery.
