Slavic tribes of Slovakia
Slovakia's current name (Slovensko) just refers to generic Slavs rather than a particular Slavic tribe. Sometimes, the Slavs that historically inhabited Slovakia are generally referred to as 'Vah Slavs' (named after the Vah River Basin), but that is also not a tribal name but just a name coined to differentiate them. Here is an example:

Slovaks were also historically called Tóth by Hungarians but that name just referred to generic Slavs (and later Slovaks) rather than a specific tribe. The term Tóth is of Germanic origin meaning "nation/people" (cognate to Deutsch) and came to Hungarian via the Goths (who lived in Slovakia).
I've also heard that they might have been descended from the "Slavic tribe" known as Moravians, but I doubt there was ever such thing as a Slavic tribe called "Moravians". The only reference to anything related to Moravians is in Byzantine sources regarding Great Morava (Megale Moravia) and it is just a name given by the Byzantines based on their location being around the Morava River rather than it being a tribal name.
So does anyone know about the existence/records of the names of any Slavic tribes of Slovakia?
