Welche Nation außer Polen hat den größten Anspruch auf das Erbe des polnisch-litauischen Commonwealth?

The wording is ugly. What does “claim” even mean? Denying other countries something?
PLC is an integral part of Belarusian history, and thats a historical fact.

It’s stupid to choose one. Polish culture was obviously predominant in the state, especially after 1696, but it’s also incorrect to name that country just Poland, because the GDL, as well as Lithuanian and East Slavic cultures within it did develop as well.

I’d say that the most important thing to consider here is that there were no nation states in that era. So, people were split among multiple kingdoms with low respect to their culture and nationality. Moreover, there was no state policy which would build a nation. The idea of a nation state was born approximately in the times of Partitions of Poland, so it’s just silly to draw a clear line from RON to any of states existing on its lands now. It’s interesting and important to learn its history and culture but arguing what country deserves more to be considered its successor is a Special Olympics discipline.

Lithuania

Poland, Lithuania, Belarus, Ukraine all had their respective cultures develop within the PLC. But claiming heritage to something that disappeared more than 200 years ago is pointless, and matters only if you think a sense of identity needs to be tied to some great historical deeds. As much as I want to feel proud of „my ancestors‘ achievements“, I have not contributed anything to that, and as such feeling historical pride feels like compensating to me.
