Answer:
WW2 was a war that was fought because Adolf Hitler started to try to conquer the world and this was a time when many Jews were killed in concentration camps this event was called the holocuast. Adolf Hitler was from Germany and allied with Italy and the other Axis Powers (Japan, Spain.) The Allied powers (USA, England, France, and Russia) fought against him and eventually freed the Jews that were still in the concentration camps, and also freed the Countries that were under Hitlers control.
That was what happened in WW2.
