Post-Roman Realms of the Brithons
in Britannia, Armorica, & Gallaecia
(“post-Roman”, as in everthing since theImperium Romanum)
Sub-Roman (476-900s) Realmsof the Brithons
‘Sub-Roman’ is a better way to describes this period than is ‘EarlyMedieval’, though the terms are roughly equivalent.
The realms are organized here by imperial province merely for the sakeof convenience, not to claim or to suggest (or deny, for that matter) anycontinuity of the same, at least not at a provincial or diocesan level, thoughmany almost certainly were civitas-based.
Britannia Valentia
Alt Clud was by far the most enduring of the kingdoms in ‘the Old North’,established in the late 4th to early 5th century and lasting until 1124, albeitin its last decades as an appendage of the kingdom of Alba.
