Politics and warfare

Stanley B. Greenfield has suggested that references to the human body throughout Beowulf emphasise the relative position of thanes to their lord. He argues that the term "shoulder-companion" could refer to both a physical arm as well as a thane (Aeschere) who was very valuable to his lord (Hrothgar). With Aeschere's death, Hrothgar turns to Beowulf as his new "arm". Greenfield argues the foot is used for the opposite effect, only appearing four times in the poem. It is used in conjunction with Unferð (a man described by Beowulf as weak, traitorous, and cowardly). Greenfield notes that Unferð is described as "at the king's feet" (line 499). Unferð is a member of the foot troops, who, throughout the story, do nothing and "generally serve as backdrops for more heroic action."

Daniel Podgorski has argued that the work is best understood as an examination of inter-generational vengeance-based conflict, or feuding. In this context, the poem operates as an indictment of feuding conflicts as a function of its conspicuous, circuitous, and lengthy depiction of the Swedish–Geatish wars —coming into contrast with the poem's depiction of the protagonist Beowulf as being disassociated from the ongoing feuds in every way. Francis Leneghan argues that the poem can be understood as a "dynastic drama" in which the hero's fights with the monsters unfold against a backdrop of the rise and fall of royal houses, while the monsters themselves serve as portents of disasters affecting dynasties.
