In hopes of keeping fictional speculation at bay, and legitimate history accurate, most especially about the claims that the Abdication of Nicholas was somehow "alleged" but not genuuine, allow me to post the exact translation of Nicholas II's own PERSONAL diary entry on the subject...
March 15, 1917, Thursday
In the morning Ruzski came and read his very long direct-wire talk with Rodzianko. According to this, the situation in Petrograd is such that a Ministry of the Duma would now be powerless to do anything, for it has to contend with the Social-Democratic Party, represented by the workers' committee. My abdication is required. Ruzski transmitted this talk to Headquarters, and Alexeev sent it on to all the commanders-in-chief. By 2 o'clock replies were received from them. The gist of them is that in order to save Russia and keep the army at the front quiet, such a step must be taken. I have agreed. From Headquarters has been sent a draft of a manifesto. In the evening Guchkov and Shulgin arrived from Petrograd, with whom I discussed the matter, and I handed them the signed and altered manifesto. At 1 o'clock in the morning [16th] I left Pskov, with a heavy heart because of the things gone through. All around me there is treachery, cowardice, and deceit.
I hope Nicholas' own words put an end to that nonsense. The dates are New Style.
