Lenin was sent back to Russia from exile by the Germans in WW1 to destabilize russia which worked. His slogan was land, peace and bread. He formed a party called the bolsheviks, who later executed the royal family. Lenin kept the populace believing that he was helping them by improving the economy.
An unequal distribution of resources.
He believed in making a new "perfect aryan race". Jews didn't fit that description, so he decided to kill them. He killed anybody really, but Jews were his main target as he was very anti-Semitic and blamed them for basically all of the worlds problems.
