(I wrote this, it is not copy pasted from anywhere and should be a paragraph.) 
Vladimir Lenin was a soviet socialist who dedicated his life to promoting and popularizing socialism and socialist reform in Russia. 
Lenin was familiar with political unrest and his spent his early life protesting Russias rule over the people, this caused him to be exiled to far eastern Siberia. 
Lenin returned to Europe from Siberia and joined a European socialist party where he would spend his time writing socialist newspapers and waiting for a opportunity to return to Russia. 
In 1905 Russia experienced a revolution. Lenin attempted to radicalize the movement with his socialist newspapers while still being exiled in Europe. 
In 1914 Russia found itself at war with Europe. This caused major instability within the country and many began starving. This caused another revolution in the country. 
Germany was at war with Russia and knew of Lenin’s socialist writings and knew the havoc he could cause for their enemy if they sent him home, so they did. Lenin boarded a train to Saint Petersburg, Russia, where he was welcomed among the revolutionary’s and assumed control of the revolution. 
Russias government was overthrown and Lenin negotiated peace with the Germans. Lenin was now the dictator of Russia and began his socialist reform of the nation.
