Are you talking about the century where (all attributes based on self-identification) a realm ruled by a socialist party was waging war against socialist republics ruled by a communist party? Doesn't really sound like they were fighting over semantic pedantry. Or maybe they were, and they were just incredibly good at hiding it.
In the context of an alleged "art hijacking", I say it doesn't matter at all.
Yes, I was thinking about the different kinds of socialists and communists killing each other. (Edit: but I’m not talking just about state vs. state, within a country different factions were not always nice to each other.)
