Germany invaded Poland on September 1, 1939, prior to the attack on Pearl Harbor, for several reasons. One of the key factors was Adolf Hitler's expansionist ambitions, driven by his desire to establish a greater German empire (known as Lebensraum) in Eastern Europe.

To get more information about this historical event and a deeper understanding of the reasons behind Germany's invasion of Poland, you can follow these steps:

1. Start by consulting authoritative sources such as history textbooks, reputable history websites, or books focused on World War II. These sources often provide comprehensive information about the events leading up to the invasion.

2. Look for primary sources like official documents, speeches, or letters written by key figures involved in the decision-making process, such as Hitler himself or high-ranking German officials. These sources can offer valuable insights into their motivations and the political climate at the time.

3. Analyze the geopolitical situation in Europe during the late 1930s. Germany, under Hitler's leadership, had already violated the Treaty of Versailles by rearming and occupying territories such as Austria and Czechoslovakia. By invading Poland, Germany aimed to gain dominance in Eastern Europe, secure access to resources, and establish a buffer against its potential enemies.

4. Consider the ideological context of Nazi Germany. Hitler and the Nazi regime believed in the superiority of the Aryan race and sought to expand German territory by conquering and subjugating other nations. Their aggressive policies and propaganda campaign targeted Poland as a potential conquest.

By combining information from these sources and considering the geopolitical and ideological context of the time, you can gain a comprehensive understanding of the reasons why Germany invaded Poland before the attack on Pearl Harbor.
