Samo

Samo (died 658) was a Frankish merchant from the "Senonian country" (Senonago), probably modern Soignies, Belgium or Sens, France. He was the first ruler of the Slavs (623–658) whose name is known, and established one of the earliest Slav states, a supra-tribal union usually called (King) Samo's empire, realm, kingdom, or tribal union.
