The independence of Britain and Armorica was soon confirmed by Honorius himself, the lawful emperor of the West; and the letters, by which he committed to the new states the care of their own safety, might be interpreted as an absolute and perpetual abdication of the exercise and rights of sovereignty.

This interpretation was, in some measure, justified by the event.

After the usurpers of Gaul had successively fallen, the maritime provinces were restored to the empire.
Yet their obedience was imperfect and precarious: the vain, inconstant, rebellious disposition of the people, was incompatible either with freedom or servitude; and Armorica, though it could not long maintain the form of a republic, was agitated by frequent and destructive revolts.

Britain was irrecoverably lost.

But as the emperors wisely acquiesced in the independence of a remote province, the separation was not imbittered by the reproach of tyranny or rebellion; and the claims of allegiance and protection were succeeded by the mutual and voluntary offices of national friendship.
This revolution dissolved the artificial fabric of civil and military government; and the independent country, during a period of forty years, till the descent of the Saxons, was ruled by the authority of the clergy, the nobles, and the municipal towns.
