Summary of “Die 1. Phase des Ersten Weltkrieges: Kriegsjahr 1914”

Main Ideas and Concepts

Outbreak of WWI (July 28, 1914): The war began with Austria-Hungary declaring war on Serbia, triggering a chain reaction due to the complex alliance system in Europe. Russia mobilized to support Serbia, leading Germany (Austria-Hungary’s ally) to declare war on Russia and then on France. Germany’s invasion of neutral Belgium brought Great Britain into the war against Germany.

Alliance System and War Declarations: The alliances made the conflict escalate quickly: - Austria-Hungary vs. Serbia - Russia supporting Serbia - Germany supporting Austria-Hungary and attacking Russia and France - Britain entering the war due to Belgium’s neutrality violation

The Schlieffen Plan: A German military strategy developed in 1905 to avoid a two-front war defeat by: - Quickly defeating France in the west by invading through Belgium (to bypass French fortifications on the Franco-German border) - Then moving troops to the eastern front to fight Russia - The plan assumed a swift victory in the west before Russia could fully mobilize

Initial German Success and Failure: - Germany initially won battles and occupied Belgium. - The German Supreme Army Command (SOH) launched an offensive toward Paris but was halted at the Marne River by a strong French defense, including the famous transport of troops by Parisian taxis. - A critical mistake was made when Germany moved two army groups from the west to the east, weakening the western front during the decisive battle. - The Battle of the Marne ended with German retreat and the failure of the Schlieffen Plan, marking the end of hopes for a quick victory in the west.

Eastern Front and the Battle of Tannenberg: - Despite the late arrival of German reinforcements, General Hindenburg decisively defeated a larger Russian force in East Prussia. - The battle was renamed “Battle of Tannenberg” for propaganda, referencing a historical German victory. - This victory stopped the Russian offensive but did not end the war.

Conclusion on the First Year of WWI: - No decisive victory was achieved on either front. - The war transitioned from mobile warfare to entrenched, costly trench warfare (war of attrition). - Initial enthusiasm for a quick war faded into disillusionment as massive casualties mounted (around one million dead). - Both sides realized that a swift and easy victory was no longer possible.
