The invasion of Poland, which began on September 1, 1939, marked the beginning of World War II. It was carried out by Nazi Germany, under the leadership of Adolf Hitler, and it was a pivotal event that led to the involvement of major world powers in the war.
One of the main causes of the invasion was Hitler's desire for territorial expansion and the implementation of his aggressive expansionist policies, known as Lebensraum. He aimed to annex Polish territories and unite all German-speaking people under one nation.
The invasion of Poland was a coordinated attack by Germany, which was quickly followed by the Soviet Union's invasion from the east on September 17, 1939. The Polish army was ill-equipped to defend against the German blitzkrieg tactics and the simultaneous attacks from both sides.
The invasion of Poland led to the immediate occupation of the country by German and Soviet forces. This event also prompted the United Kingdom and France to declare war on Germany, officially marking the beginning of World War II in Europe.
By studying the invasion of Poland, we gain valuable insights into the complex geopolitical factors that contributed to the outbreak of World War II and the devastating impact it had on the global stage.
