Germany annexes former Polish regions

Germany's annexation of former Polish regions marked a pivotal shift in the geopolitical landscape of Central Europe. The annexed territories included Upper Silesia, West Prussia, Pomerania, Poznan, Ciechanow (Zichenau), parts of Łódź, and the Free City of Danzig. This action was part of a broader strategy to expand German territory and influence following the invasion of Poland. The annexation resulted in the establishment of two new administrative districts: Danzig-West Prussia and Posen, which was later referred to as District Wartheland or Warthegau. This restructuring aimed to integrate these regions into the German state and facilitate the Germanization of the local population. The impact of this annexation was profound, leading to significant demographic and administrative changes. The areas not directly annexed by Germany or the Soviet Union were placed under a German civilian administration known as the Generalgouvernement. This administration was responsible for overseeing the occupied territories and implementing policies that often resulted in the oppression of the local Polish population. The annexation and subsequent policies contributed to widespread displacement, economic exploitation, and cultural suppression, which had lasting effects on the region's demographics and social fabric. The actions taken during this period set the stage for further conflict and resistance, as the local populations sought to reclaim their autonomy and identity in the face of aggressive German expansionism.
