Is that the Cliff Notes version of the story?
Stalin (the Georgian) wanted the Ukrainian breadbasket to provide food to Moscow because the revolution destroyed farming ability in Russia. Also, the revolution, as revolutions tend to do, became blood thirsty and saw the Ukrainian kulaks (small farmers and businesspeople) as needing to be destroyed.
So Stalin kicked them out of their homes and starved them. It was particularly brutal and sadistic. Read up on it. The kind of thing a person should be aware of.
