How to prevent the Russian Revolution starting with Tsar Alexander II
Known as Alexander the Liberator, Alexander II of Russia was known for "emancipating the serfs... organising the judicial system, setting up elected local judges, abolishing corporal punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some privileges of the nobility, and promoting university education" ("Reformation by the Tsar Liberator"). He became more reactionary after he was almost assassinated in 1866, but he was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881.
So, boys and girls, let's figure out how to keep Russia together, starting with Alexander's reign. In my OTL, he marries a British princess, so I figure he'd be more exposed to constitutional monarchies like Britain's, and he's succeeded by his eldest son, Nicholas II.
Should he have gone farther after emancipating the serfs? Gone a different way? Any politicians to appoint or not appoint? (This really isn't my area of history, so I'll take any help I can get!)
Thank you!
