Well, this is my first timeline, and before I start I would like to introduce you to the world of White Dawn (the name is a take-off of the name of the movie "Red Dawn", but not the content)!
First of all, to start you up, let me tell you the POD.
The POD or Point of Divergence is that the White forces in the Russian Civil War were more organized and had a more competent leadership than in OTL.
As a result, they win the war, reinstalling the Romanovs who were rescued in the last minute, leading to a very different Europe for the better part of the xx century.
Now, I shall give you the timeline! (coming soon)
