You can hardly call most of those successful though. Most Tuchanons were swiftly destroyed by their neighbors, Coimbraheim was annihilated by the Titans after a week. There is Fronen, which I believe was refounded, and which is pretty successful.
In name only. The new Fronen might have a very few people who were at some point in the upper echelons of the old one, but by and large, it's a completely different realm, with everything but the name totally changed.
