During the Second World War, Nazi Germany occupied the city on 19 September 1941 (see the Battle of Kiev). Overall, the battle proved disastrous for the Soviet side but it significantly delayed the German advances. The delay also allowed the evacuation of all significant industrial enterprises from Kiev to the central and eastern parts of the Soviet Union, away from the hostilities, where they played a major role in arming the Red Army fighting the Nazis (see, for example, the Arsenal Factory).
