The German-Polish War was a conflict between Germany and the Polish State lasting from September 1939 to June 1940.The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact.To the shock of the Germans,the Soviet Union did not join the war after seeing German losses.The campaign ended in June 1940 with Polish-Allied Victory and the execution of Hitler.

German forces invaded Poland from the north, south, and west the morning after the Gleiwitz incident. Slovak military forces advanced alongside the Germans in northern Slovakia. As the Wehrmacht advanced, Polish forces withdrew from their forward bases of operation close to the Germany–Poland border to more established defense lines to the east.After the mid-september Polish victory at the Battle of the Bzura,the war turned advantageous to the Poles under Rydz-Śmigły.

On 3 September, based on their alliance agreements with Poland, the United Kingdom and France declared war on Germany and began sending aid to Poland after the Royal Navy defeated the Kriegsmarine at the Battle of the Denmark Strait.France invaded a small part of Germany in the Saar Offensive and held their positions as they sent divisions to Poland.

## Background

On 30 January 1933, the National Socialist German Workers' Party, under its leader Adolf Hitler, came to power in Germany. While some dissident elements within the Weimar Republic had long sought to annex territories belonging to Poland, it was Hitler's own idea and not a realization of any pre-1933 Weimar plans to invade and partition Poland, annex Bohemia and Austria, and create satellite or puppet states economically subordinate to Germany. As part of this long-term policy, Hitler at first pursued a policy of rapprochement with Poland, trying to improve opinion in Germany, culminating in the German–Polish Non-Aggression Pact of 1934. Earlier, Hitler's foreign policy worked to weaken ties between Poland and France and attempted to manoeuvre Poland into the Anti-Comintern Pact, forming a cooperative front against the Soviet Union. Poland would be granted territory to its northeast in Ukraine and Belarus if it agreed to wage war against the Soviet Union, but the concessions the Poles were expected to make meant that their homeland would become largely dependent on Germany, functioning as little more than a client state. The Poles feared that their independence would eventually be threatened altogether; historically Hitler had already denounced the right of Poland to independence in 1930, writing that Poles and Czechs were a "rabble not worth a penny more than the inhabitants of Sudan or India. How can they demand the rights of independent states"
