This poem summarizes the many changes experienced by the Anglo-Saxons over time, from their migration to England after the Romans left, through the various kingdoms that arose, invasions by Vikings and Normans, and the ultimate decline of Anglo-Saxon culture with the Norman conquest of 1066. The poem touches on influences like Christianity, the writing of Beowulf, battles between kings, and how William the Conqueror forced the crown upon himself, ushering in a new era that led to the decline of Anglo-Saxon people and culture.
