How could Russia become a Constiutional Monarchy? Several PODs come to my mind:
1. Tsar Alexander II surives and goes on to accept the constitution he was considering (I realize this is before 1900)
2. Tsar Nicholas II enacts real reforms and accepts a constitution after the Revolution of 1905.
3. The Monarchy is more respected in 1917, (maybe a different non-German Empress and no Rasputin would help) so the February revolutionaries set up a Consititutional Monarchy instead of a republic.
Which POD do you think is the best? Are there any other PODs you can think of, if so please share.
