2 spoils of the battle in Beowulf

Fifty years after killing the evil Grendel and his mother, the epic hero, Beowulf, faces his third and final monster, a dragon that has been attacking Geatland. But this last battle will be completely different from the ones before, and it spells the end for our epic hero. After fighting both Grendel and his mother, Beowulf ascends to the throne of the Geats. He rules wisely for 50 years, bringing prosperity to Geatland. When Beowulf is an old man, a dragon that lies guarding a horde of treasure is disturbed. The dragon then becomes enraged.

the passage can be best described as: "the british legislature extended an unwarranted jurisdiction".

we can say that because the text clearly states how the people of the colonies warned the british about their excessive desire to rule over them, without taking into consideration the difficulties their brothers had experienced in america: they struggled to establish the colonies, to adapt to new types of weather, fight with the natives, etc., and how they now see (or then saw) the only way out was to cut all ties with the british, since they ignored the people's petitions.
