Why did Germany invade Poland?

Reasons Behind Germany's Invasion of Poland

On September 1, 1939, in Sęp?lno Krajeńskie, Poland, Adolf Hitler launched an invasion of Poland. His goal was to establish a German presence in the region, as he viewed the Polish population as inferior and primarily suitable for labor purposes. In the last quarter of 1939, the Nazis executed approximately 65,000 individuals, both Jewish and non-Jewish Poles.
