Its spelled Holocaust and it happened in 1939 when Hitler(dictator from Germany) invaded Poland. It lasted all through WW11(1939-1945), and started in Germany and spread to other countries under German control. there were concentration camps in Poland, for example.
Joseph Stalin led the Soviet Union. Stalin took over after Lenin died. Stalin was not Lenin's choice as a successor but Stalin schemed and came into power, basically he stole the title. He was in power before and after WW11. He died in 1953. In WW2 he had signed a non-agression pact with Hitler, but ultimately became allied with France, Great Britain, the United States and the other Allied countries.

The industrialisation was started at the beginning of XX century, but the main industrialization steps were after Soviet Union was estabilished. The industrialisation allowed to create military equipment after Third Reich countries (Germany, Hungary, Austria, Luxemburg etc) started agression against S.U.
