Final answer:
After Beowulf's death, the Franks and the Frisians are anticipated to declare war on Beowulf's people, the Geats.
Step-by-step explanation:
The Franks and the Frisians will declare war on the Geats now that Beowulf has died. This statement is rooted in the epic poem Beowulf, which is part of the English literary canon. After Beowulf's death, his people, the Geats, fear that their enemies will take the opportunity to attack them, knowing that the great hero who protected them is no longer alive to defend their kingdom.
