Kingdom of Poland (1917–1918)

The Kingdom of Poland (Polish: Królestwo Polskie, German: Königreich Polen), also known informally as the Regency Kingdom of Poland (Polish: Królestwo Regencyjne), was a short-lived puppet state of the German Empire and polity that was proclaimed during World War I by it and Austria-Hungary on 5 November 1916 on the territories of formerly Russian-ruled Congress Poland held by the Central Powers as the Government General of Warsaw and which became active on 14 January 1917. It was subsequently transformed between 7 October 1918 and 22 November 1918 into the independent Second Polish Republic, the customary ceremonial founding date of the latter being set at 11 November 1918.

In spite of the initial total dependence of this client state on its sponsors, it ultimately served against their intentions in the aftermath of the Armistice of 11 November 1918 as the cornerstone proto-state of the nascent Second Polish Republic, the latter composed also of territories never intended by the Central Powers to be ceded to Poland, and therefore played a crucial role in the resurrection of Polish statehood.

Rationale

The decision to propose the restoration of Poland after a century of partitions was taken up by the German policymakers in an attempt to legitimize further imperial presence in the occupied territories and create a buffer state to prevent future wars with Russia. The plan was followed by the German propaganda pamphlet campaign delivered to the Poles in 1915, claiming that the German soldiers were arriving as liberators to free Poland from subjugation by the Russian Empire. However, the German High Command under Erich Ludendorff also wanted to annex around 30,000 square kilometers of the territory of former Congress Poland, and planned to evict up to 3 million Poles and Jews to make room for German colonists in the so-called Polish Border Strip plan. The German government used punitive threats to force Polish landowners living in the German-occupied Baltic states to relocate and sell their Baltic property to the Germans in exchange for entry to Poland. Parallel efforts were made to remove Poles from the Polish territories of the Prussian Partition.

Planning

Germany

With the onset of the war in 1914, for the purposes of securing Germany's eastern border against the Russian imperial army, Theobald von Bethmann Hollweg, the German chancellor, decided on the annexation of a specific strip of land from Congress Poland, known later on as the Polish Border Strip. In order to avoid adding the Polish population to the population of imperial Germany, it was proposed that the Poles would be ethnically cleansed to a proposed new Polish state further east, while the strip would be resettled with Germans.
