Poland, Czech Rebublic,Slovakia,Slovenia,Russia, Ukraine, Byelarus; Croatia, Serbia, and that's all I think. ==

Plus Bulgaria, Makedonia, Bosnia (yes they muslim but IMHO they are slavic)? Bulgarians invented slavic alphabit the cyrillic. And Romania?

But anyway ther no pure slavs. Russians for example the decendants of finno-ugorish people (ethnically brothers to hungarinas and estonians) and eastren slavs.
Ancient Rus was founded by vikings. Which created the line of russian czars till Ivan the Terrible.
That is no issue for other slavic countries.

Chekhs are mix between germans and slavs. Polacks is mix too. Many ukranians and bellorussians and jews blended in polacks. At least the name Bogdan (your name) is ukranian.
In middle ages the most of polish aristocracy was decendants of ancient russian dukes. SO one polish duke (Vishnevetskii my guess) once said that he has more rights for russian czarship then Romanovs his days ruling dinesty:) and he was right he was direct decendant of Rurik the first russian king.
