Germany Declares War on Russia

Historical Overview

In direct response to the Russian general mobilization, the German Empire formally declared war on the Russian Empire and simultaneously ordered its own full military mobilization. The primary strategic objective of the German leadership under Kaiser Wilhelm II and the General Staff was to adhere to the rigid timeline of the Schlieffen Plan, forcing a decisive move before Russia could deploy its massive manpower. This declaration shattered the remaining diplomatic avenues of the July Crisis, automatically triggered European alliance obligations, and formally escalated the regional Balkan conflict into World War I.
