Why did Nazi Germany occupy Warsaw during World War II?

Nazi Germany occupied Warsaw as part of its broader invasion of Poland, which marked the beginning of World War II in 1939. The occupation was the culmination of a coordinated military assault, known as blitzkrieg, designed to overwhelm Polish defenses through superior air power and armored divisions.12

Following the siege of Warsaw, which resulted in significant casualties and the destruction of infrastructure, the city was forced to surrender due to a lack of supplies. The subsequent Nazi occupation was characterized by a systematic effort to reduce Warsaw to a provincial city. This involved the widespread plundering of cultural treasures and the forced relocation of residents to labor or concentration camps. Additionally, the Nazis established the Warsaw Ghetto, confining hundreds of thousands of Jewish citizens in inhumane conditions as part of a campaign of persecution and eventual annihilation.2
