Chief of the German General Staff Alfred von Schlieffen develops the 1905 deployment concept later labeled the Schlieffen Plan, envisioning a rapid right-wing envelopment through Belgium to defeat France before shifting forces east.
Germany’s Western Front campaign opens by violating Belgian neutrality, triggering immediate military operations in Belgium and accelerating international escalation (including Britain’s entry into the war).
German forces begin attacks on the fortified position of Liège, the opening major engagement of the invasion of Belgium; the unexpectedly stubborn defense delays German movement and highlights the role of modern fortresses and siege artillery.
The Prussian War Ministry decrees the Kriegsrohstoffabteilung (KRA) to centrally manage scarce raw materials under blockade pressure, a key step in German home-front economic mobilization during industrial war.
After rapid advances in August, Germany’s push toward Paris is checked as the Franco-British counteroffensive forces a German retreat; the failure to secure a quick victory contributes to entrenched stalemate on the Western Front.
Intense fighting around Ypres during the “Race to the Sea” helps complete a continuous Western Front line; German attempts to break through toward Channel ports fail, cementing positional warfare.
German forces conduct the first large-scale poison-gas attack on the Western Front, releasing chlorine at Ypres; although the attack creates a gap, Germany fails to achieve a decisive breakthrough, and chemical warfare becomes a persistent feature of the conflict.
Germany launches its major 1916 offensive at Verdun, aiming to exhaust French forces in a prolonged battle of attrition; Verdun becomes a defining struggle for manpower, artillery, and national morale.
After Falkenhayn’s dismissal, Paul von Hindenburg and Erich Ludendorff assume leadership of the Supreme Army Command (OHL), reshaping German strategy and intensifying demands for domestic economic and labor mobilization.
Germany establishes the Kriegsamt (Supreme War Office) to coordinate economic mobilization and implement labor obligations associated with the Hindenburg Programme, further militarizing management of production and manpower.
During the winter of 1916–1917, poor harvests and the Allied blockade contribute to severe civilian shortages in Germany; reliance on turnips as famine food becomes emblematic of mounting social strain and weakened morale.
The empire passes the Auxiliary Services Act to expand labor control for war production, obligating German males (within specified ages and exemptions) to perform national service and supporting the broader Hindenburg-era mobilization drive.
Germany restarts unrestricted U-boat attacks in an attempt to break Britain’s supply lines; the policy sharpens conflict with neutral states and becomes a major factor pushing the United States toward belligerency.
With forces freed from the Eastern Front, Germany launches Operation Michael—the first and largest phase of the 1918 Spring Offensive—using intense artillery preparation and infiltration tactics to rupture British positions, seeking a decisive result before American power fully arrives.
Sailors’ revolt at Kiel over a proposed final fleet action triggers rapid spread of workers’ and soldiers’ councils; the uprising becomes the catalyst for the broader 1918 revolution that ends imperial rule.
