I want to know the answer to the following question:
When was the first Bulgarian Empire founded?
All the background I'm provided with is that "In the 7th century, the Frankish merchant Samo, who supported the Slavs fighting their Avar rulers, became the ruler of the first known Slav state in Central Europe, which, however, most probably did not outlive its founder and ruler.". Is that enough to answer the question?
Answer: no
