I want to know the answer to the following question:
What is the oldest Slav state in Central Europe?
All the background I'm provided with is that "In this period, there existed central Slavic groups and states such as the Balaton Principality, but the subsequent expansion of the Magyars, as well as the Germanisation of Austria, separated the northern and southern Slavs.". Is that enough to answer the question?
Answer: no
