Learnings: Anglo-Saxon Warfare

Aristiocratic Anglo-Saxon men used war to maintain social order—and to ensure their own powerful positions. While the nobles lived the "warrior's way," those with a lesser or "middle" status, such as the ceorl, had to wait until they were called to battle to earn prestige and honour.
War bands were almost exclusively made up of teenagers and young men (15-30 years old) whose will to prove themselves in combat resulted in fierce competition within the ranks. Their "friendly" rivalries with their brothers-in-arms were as vital to forging combat skills as the battles in which they faced a common enemy.
Regular warfare was also a good way to keep a war band together. Such groups depended on victories—and the spoils that came with them—for survival. A successful campaign meants wealth, but also honour. Prestige and renown contributed massively to social status, and were some of the major ways a man could distinguish himself from his peers.
Offa's Dyke, a ditch of earth distinguishing Welsh territories from Mercian ones, is a good example of a king exercising his control, or dominion. According to folklore, King Offa of Mercia ordered the construction of the dyke, a section of which can be seen in this image.
