Question

Why did the invasion of poland launch World War II? (1 point)

Answer 1

The invasion of Poland by Germany on September 1, 1939, marked the official start of World War II because it prompted Britain and France to declare war on Germany on September 3, 1939, in defense of Poland. The invasion violated international agreements and demonstrated Nazi Germany's aggressive expansionist policies, leading to a broader conflict as alliances and tensions escalated across Europe.
