Hello historians,

This question's been on my mind for a while now, so I thought I'd ask about here. Gavrilo Princip, the dude who shot Archduke Franz Ferdinand, belonged to the revolutionary group Young Bosnia. As I understand, this group had two wings, one which was Yugoslavist (unification of all Slavs into a Yugoslavia), and another which was Pan-Serb (unification into the already existing Serbia). While Princip was a Bosnian Serb himself, I can't find if he was belonged to the Yugoslav wing, or the Pan-Serb one. Is this known?

Thanks, historians.
