The Septemberprogramm was the plan for the territorial expansion of Imperial Germany, prepared for Chancellor Theobald von Bethmann-Hollweg, at the beginning of World War I (1914–18). The Chancellor's private secretary, Kurt Riezler, drafted the Septemberprogramm on 9 September 1914, in the early days of the German attack in the west, when Germany expected to defeat France quickly and decisively. The extensive territorial conquests proposed in the Septemberprogramm required making vassal states of Belgium and France, in western Europe, and seizing much of the Russian Empire, in eastern Europe. The Septemberprogramm was not effected because France withstood the initial German attack, and the war devolved into a trench-warfare stalemate, and ultimately ended in German defeat.
As geopolitics, the Septemberprogramm itself is a documentary insight to Imperial Germany's war aims, and shows the true scope of German plans for territorial expansion in two directions, east and west. Historian Fritz Fischer wrote that the Septemberprogramm was based on the Lebensraum philosophy, which made territorial expansion Imperial Germany's primary motive for war. Jonathan Steinberg has suggested that if the Schlieffen Plan had worked, and produced a decisive German victory, like the Franco-Prussian War of 1870, the Septemberprogramm would have been implemented, thus establishing German hegemony in Europe.
