The question is disputable as there was no one leader of the USSR (A confederation of states including but not limited to Russia which was controlled in Moscow IE not just Russia.)
During the 1920s due there was a power struggle which began after the death of Lenin in January 1924. Various candidates such as Trotsky, Stalin, Bukharin and others fought for party support - this struggle was eventually won by Stalin who gained enough popularity within the Communist Party to then become the leader of the USSR in 1928.
Stalin's leadership was long, brutal but arguably successful only ending with his death in 1953. Tens of millions of Soviet citizens died for a large number of reasons while he stood at the helm; however Russia did advance at a huge pace from an obscure peasant society in the 1920s that was largely irrelevant to global affairs to a modern industrialised state and after his death ultimately the world's other superpower only matched by the United States.
