Answer:
Supporters of the king
Step-by-step explanation:
supporters of the king was more interested in the Beowulf manuscript rather than Parliamentarians because the supporters of the king acts as protagonist Beowulf who was a hero of the Geats, comes to the help king Hrothgar, who is king of the Danes. The monster Grendel causes damage to the kingdom of king Hrothgar. Beowulf comes to help the king Hrothgar by killing Grendel with his bare hands and his mother with his sword. So the supporters also acts as protagonist Beowulf who supports their king.
