Ozzymandus, I’ll give you that Princip was indeed an assassin (not by “profession” but rather just in this one instance - in Sarajevo), but as far as Princip being a “terrorist” - it really all depends on your point of view.
Let me ask you this - and anyone can chime in here -
When Hitler was rising in the 1930’s, if an assassin had stopped him dead in his tracks, literally and figuratively, how do you think that “assassin would have been viewed by history?
(I don’t equate Archduke Franz Ferdinand with Hitler by any stretch, because I actually feel that the Archduke was the most reasonable and “sympathetic” of the Habsburg elite, but I’m making the analogy here for the sake of discussion.)

You say you don’t equate Ferdinand with Hitler, but you do. What if some Indian nationalist had assassinated Queen Victoria? How would he be remembered? That seems like a more apt comparison.
