After everyone had calmed down (probably because Lenin told them to), Russia got to work doing what Lenin said they should do. With Lenin in charge, peasants could be all "hey, would you like to buy this apple I grew?" and people didn't have to be like "no! I would not like to because that is against the law!" Instead, they could just buy stuff from peasants and peasants could sell stuff to whoever they wanted. It seemed like a pretty good idea to everyone.
In 1922, Russia because known as the Union of Soviet Socialists, or the USSR. Luckily for them, the acronym was shorter than writing out "Russia" so the long name didn't start some sort of writing revolt. The USSR saw nationalism as a big threat. The issue with this was that in the 20th century, and even in the 19th century, basically everyone everywhere was like "I heart my country" and wore pins that said "I Love Nationalism".
In 1924, the Bolshevik party became the Communist Party and they held all the power in Russia, except they told people that the workers held all the power because they were a pretty sly bunch.
When Lenin had had a stroke in 1922, this guy called Stalin had gotten really excited and had been like "OMG, I'm gonna lead Russia next!" and beat anyone up who said they didn't want him to.
This beating up eventually became a habit. So when Stalin actually did run Russia, he was like "Yo peasants! You know how Lenin let you sell people your wheat or whatevah? NOT ANY MORE!" and he put all the peasants into communal farms, which they hated. He also took his freakish amount of anger out on the workers by setting impossibly high quotas for everything.
The workers were like "Stalin, we can't do that!" and he was like "Oh yeah? Then I'll kill you!"
Because he wanted to be seen as a Ladies Man, Stalin gave women equal rights. His plan to have loads of girlfriends never really worked, but by 1950 seventy-five percent of doctors in the USSR were women.
