Britannia Superior

Britannia Superior is described as the southern part of the British Isles. It extends from Cornwall up to the Hadrianic Strait, which separates both Britannia Superior and Britannia Inferior. Britannia Superior is host to various independent states, such as the prominent Kingdom of Anglia, which is the largest on the isle, or the various Welsh states. As such, the island is host to varying cultures and languages, and as such, conflict.

History
Britannia Superior was first colonised by the Romans under Emperor Claudius in 796 AUC (AD43). The entire island remained a Roman colony up until the waning years of the Roman Empire, c. 1554 AUC (AD800), until the recently migrated Angles and Saxons, which had settled and were given land in western Britannia Superior along the border of Wales by a Foederati treaty, had converted to Byzantine Christianity and rallied behind a tribal leader named Wynnstonn, leading to the start of the War of the Angles. After having successfully pushed back the Romans from middle Britannia Superior after this 1-year conflict, they established their own local tribal kingdoms and entered in an Anglo-Saxon federation.

Post-Roman Britannia Superior
With the defeat of the Romans in middle Britannia Superior, and their evacuation of Wales and Cornwall into the Roman enclaves in the south, Roman order quickly gave way to hastily established tribal kingdoms. Wynnstonn's death in 1600 AUC (AD846) had formed the Kingdom of Anglia out of the loose Anglo-Saxon federation, and the fall of the Roman Empire in 1 AIE (AD852) brought about the independent Britannic Roman Enclave. In Cornwall, the evacuation of Roman authorities had allowed the Kingdom of Dumnonia and the Kingdom of the Durotriges to establish themselves as fully independent entities. In Wales, various Celtic kingdoms were established.

Religion
The most prominent religions in Britannia Superior are the Druidic pagan religions practised by the Celts and Byzantine Christianity practised by the Kingdom of Anglia and the Duchy of Powys-Morgannwg.
