Very often in Russian history we see revolutionaries (nationalists and socialists both) attempt and succeed at assassinations and revolts. The czar often imprisoned these people, then exiled them for several years in Siberia. For example this happened to Lenin. Where they were then able to come back and cause more trouble for the Czars later. Sometimes escaping before their exile was “finished”. Was this seen as a permanent solution? Why not hang them, which was otherwise common at the time.
Im very late but he did do that. He had a secret police that practiced public executions. Lenin’s brother who was a saboteur was executed in front of Lenin allegedly by the secret police. The thing you have to realize is that exile doesn’t mean what you think it means. After Lenin’s brother was executed Lenin and his mother became pariahs. No one helped out in either the funeral or attended it. The Russian tsar had (and still has) a cult of personality that sees him as the father of the Russian people. He’s the closest thing to the quintessential “Russian spirit”. For example Trotsky lived in exile in Mexico but although he was restricted in what he could do he had a lot of liberties and people didn’t find him to be a pariah. That’s the type of exile you’re thinking of. The people who were exiled by the tsar instead lived super hard lives and were probably spied on by the secret police. It was a sort of “red mark of shame” that was also psychological and social not to mention physical. The tsar in exiling someone really sent them out to live a life of shame and death. The closest modern equivalent are the people who manage to leave Guantanamo. For example both the inmates of Guantanamo and Lenin couldn’t “hang out” with their peers. Lenin for one was forced out of action in his secret group of agitators and had to live several towns over unable to meet with them or his wife.
