AHC West Roman Rump State

With any POD between 1 AD and 476, have a rump state of the Roman Empire/ Western Roman Empire survive anywhere in Western Europe at least to 1800. Bonus points if the rump state is not Christian or survives to the present day.

Rules are that the state must have continuity of government with the Roman Empire(not just claiming the legacy of Rome), be independent of Byzantium, be a true rump state with limited territory and power(the smaller and more isolated the better), and no ASBs or magic(obviously).

EDIT: Can someone please put this in Before 1900? I put this in the wrong forum, apologies.

Maybe San Marino is one already.

Our information on how it was founded comes from later tradition, but it doesn't seem to have been incorporated into the Ostrogoth kingdom or any of its successors. It must have been either a secessionist country (a little one) in the late empire, or else associated with the late empire until 476 then a true rump state.

The major rump states as of 476 (per Charles Oman, The Dark Ages) were Dalmatia, Syagrius's kingdom in Northwestern Gaul and Britain. There are timelines on here which keep one or both of the last two going for a long time.

A state comprising of Italy, Africa, Hispania is a good bet. The Domain of Soissons is another possible option, if the Franks are beaten and the Visigoths fall to Balkanization.
 
Bonus points if the rump state is not Christian ....

Now, this is the tricky part. If the romans manage to get Africa back or avoid the conquest of Africa by the Vandals at all, there is a chance, that a smaller roman empire with Italy & Africa survives. But it is definitely christian. And the overall cultural change, which already started long before will hit this empire, too.

If an ATL butterflies away Christianity's dominance in later roman policies, and the Empire still falls to barbarians, then you could have a rump state in Hispania or Africa with growing pagan sects...

The earliest POD is 1 AD. Plenty of time to smother Christianity in the cradle(or, rather, the manger).
 
Carausius or a similar revolt in Britain, establishing a unified Roman government there. So long as they can hold off any concerted invasion from the continent, they should be fairly stable.

Weren't there way too many Angles and Saxons to make that viable?

Historical consensus today is that the Anglo-Saxon migration was less a massive migration and more higher-ranking Anglo-Saxons establishing themselves in British society and gradually converting those around them to their culture. Even at the height of the migrations, Britons outnumbered Anglo-Saxons 4:1. With a strong, unified, Roman state in Britain, I doubt a migration like OTL's would have been possible, especially as the Roman position in Britain would be reinforced by those from across the Empire migrating to Britain as things went south in their home provinces.
 
Carausius' revolt was crushed in 296. The Saxons don't actually start seriously settling in Britain for another century, roughly. In Carausius' time, the Franks were just as prone to hop over the Britain for some raiding as the Saxons were.

Also, if we presume that Britain can break away, it also follows that the Empire as a whole might be significantly weaker, making Gaul an even more tempting target.
