Clarification: D-Day as most people refer to the Invasion of Normandy is only one D-Day of hundreds. D-Day is the first day a military mission, campaign or attack is referred to as day one. The next days are called D-day plus one, D-day plus two and so forth until the end of the battle or campaign.

Normandy Invasion had to occur to get the Allied Troops into Germany Occupied European nations to get them liberated of the nasty Nazi Germans.

World War 2 was caused by Adolf Hitler and the Nazi Third Reich invading other nations and taking them over. See link below.
