Final answer:
The large group of Viking invaders in England was known as the Great Fleet, notorious for significant raids and conquests.
Step-by-step explanation:
The huge band of Viking invaders that landed in England were organized into what was known as the Great Fleet. By the late ninth century, this formidable force had conquered the Anglo-Saxon kingdom of East Anglia and established a significant presence in eastern England.
Vikings were seafaring people from the late eighth to early 11th century, originating from the Scandinavian region, which includes present-day Denmark, Norway, and Sweden. Known for their expertise in shipbuilding and navigation, Vikings explored, traded, and raided across Europe, and Asia, and even ventured as far as North America. Notorious for their large-scale raids, the Vikings in 885 besieged Paris with at least 700 ships, and earlier in 845, forced Hamburg to pay a massive ransom.
