According to the fount of all first glance research, Tsar Nick and his family were executed by an action of the Ural Soviet of Worker's Deputies, headed by Yakov Yurovsky. They said that the White Guards were attempting to rescue the Romanovs, and the German government was known to favor the restoration of the monarchy.Tsar Nick, fake God on Earth.
So, under wartime conditions, the Presidium of the Ural Soviet decided to execute the Romanovs, and Yurovsky and his 10-man firing squad carried out the execution. They felt there was no time for a proper trial, but said that Tsar Nick was "guilty of countless, bloody, violent acts against the Russian people." I have no reason to doubt that judgment.
Yurovsky said he personally fired the shot that killed the Tsar. Yes, Yakov Yurovsky was born Jewish. But he converted to Lutheranism in the early 1900's.
I guess maybe Christians shouldn't be so eager to accept converts, but should ask some questions to find out what those "cryptos" are really thinking? At any rate, the (Lutheran) gates of heaven were opened, and Yurovsky was presumably washed in the blood of the Lamb. So his sins have been forgiven, right?
Yes you are, although Miss Kitty is likely to miss your point. Continuing a tradition dating back to the pharaohs of Egypt, the Jewish royal family frequently engaged in marriages with sisters, daughters or first cousins. It was also common for elderly rulers to marry much younger women in their immediate family. The Bible mentions a number of examples.(and I'm not 'really' making some snide comment about Trump dating Ivanka).
Romans and Greeks found this practice rather scandalous, and complained about it for propaganda advantage. But their royals were not above occasionally doing the same thing themselves.
