The Romanovs fell because they were not considered Russian. The Bolsheviks came to power under nationalistic slogans against the anti-national monarchy. Nicholas II had only 1/64 Russian blood and behaved like a German. And people saw him as a German (especially after Bloody Sunday). No Bolsheviks incited the people to go to the Tsar's palace; it was a provocateur from the Tsar's security service, the priest Gapon, who did it. The Bolsheviks, the real ones (before Khrushchev), sought power not for personal gain or a simple thirst for power. No, it's much scarier than that. And Orthodoxy had outlived itself back in the time of Peter the Great, when he subordinated the church to the state. The Bolsheviks saved the country and gave it the opportunity to live another 70 years
