What were the nationalities of Slavic peoples?

It's not quite accurate to talk about "nationalities" of Slavic peoples in the way you're asking. Here's why:

* "Slavic" is an ethnicity, not a nationality: It refers to a shared language family and cultural heritage, not a single nation or citizenship.

* Slavic peoples are spread across many nations: They live in various countries, each with its own distinct nationality:

* Eastern Slavs: Russia, Ukraine, Belarus

* Western Slavs: Poland, Czech Republic, Slovakia, Slovenia

* Southern Slavs: Bulgaria, Croatia, Serbia, Montenegro, North Macedonia, Bosnia and Herzegovina, Slovenia

* National identities are complex: Even within these countries, there are often diverse ethnicities and regional identities alongside the national one.

So, to answer your question more accurately, it would be better to say:

* Slavic peoples have a wide range of nationalities, reflecting the various countries they inhabit.

* Each individual Slavic person has a specific nationality based on their citizenship.
