Final answer:
Scholars believe that Beowulf was brought to England during the Anglo-Saxon period, which lasted from approximately 400 CE until 1066, a time rich in cultural exchanges and literature despite being marred by Viking raids.
Step-by-step explanation:
Beowulf, a monumental work of Anglo-Saxon literature, is believed by scholars to have been brought to England during the period of Anglo-Saxon England, which spanned from around 400 CE to the Norman Conquest in 1066. The poem is written in Old English, a language that was spoken in England after the Roman legions withdrew and the Anglo-Saxons began to establish their rule. The frequent Viking raids during the late eighth century and the establishment of a Viking kingdom in Anglian territory provide context to understand the time period of Beowulf's arrival in England.
The Anglo-Saxons, who originated from areas around present-day northern Germany and Denmark, fostered a culture of learning and produced extensive literature, with Beowulf being the best preserved example. Considering the historical events and the archeological findings like those at Sutton Hoo, scholars can piece together the story of Beowulf's journey to England, though the exact details and date remain a subject of scholarly debate.
