Why Did Italy Enter World War 2? This article provided me with the answer I needed. Personally, I love history. My curious mind is always looking for new facts to help me better understand the war events. It was one among the most destructive conflicts in human history. I hope it doesn't happen again. Italy entered the Second World War and declared war on France in 1940. Why did they do this? A majority of historians agree that it happened because Italy was influenced by Germany during WW2. These powerful leaders wanted the world to fall, but they failed. The outcome of WW2 was disappointing for Italy and the entire world. Germany was a dangerous enemy that was ultimately defeated. It was difficult to recover from such an international conflict. I also know that countries tried to rebuild their economies and political spheres. There were many wars after WW2, but none that had such horrible consequences.
