Title: History of Germany during World War I
Content:  During World War I, the German Empire was one of the Central Powers. It began participation in the conflict after the declaration of war against Serbia by its ally, Austria-Hungary. German forces fought the Allies on both the eastern and western fronts, although German territory itself remained relatively safe from widespread invasion for most of the war, except for a brief period in 1914 when East Prussia was invaded. A tight blockade imposed by the Royal Navy caused severe food shortages in the cities, especially in the winter of 1916–17, known as the Turnip Winter. At the end of the war, Germany's defeat and widespread popular discontent triggered the German Revolution of 1918–1919 which overthrew the monarchy and established the Weimar Republic.
Title: History of Germany
Content:  Ethnic demands for nation states upset the balance between the empires that dominated Europe, leading to World War I, which started in August 1914. Germany stood behind its ally Austria in a confrontation with Serbia, but Serbia was under the protection of Russia, which was allied to France. Germany was the leader of the Central Powers, which included Austria-Hungary, the Ottoman Empire, and later Bulgaria; arrayed against them were the Allies, consisting chiefly of Russia, France, Britain, and in 1915 Italy. In explaining why neutral Britain went to war with Germany, author Paul M. Kennedy recognized it was critical for war that Germany become economically more powerful than Britain, but he downplays the disputes over economic trade imperialism, the Baghdad Railway, confrontations in Central and

Japan then formally declared war on Germany on 23 August 1914 thereby entering the First World War as an ally of Britain, France and Russia to seize the German-held Caroline, Marshall, and Mariana Islands in the Pacific.  The only major battle that took place between Japan and Germany was the siege of the German-controlled Chinese port of Tsingtao in Kiautschou Bay. The German forces held out from August until November 1914, under a total Japanese/British blockade, sustained artillery barrages and manpower odds of 6:1 – a fact that gave a morale boost during the

By 1900, Germany was the dominant power on the European continent and its rapidly expanding industry had surpassed Britain's while provoking it in a naval arms race. Germany led the Central Powers in World War I (1914–1918) against France, the United Kingdom, Russia, (by 1915) Italy and (by 1917) the United States. Defeated and partly occupied, Germany was forced to pay war reparations by the Treaty of Versailles and was stripped of its colonies as well as of home territory to be ceded to Belgium, France, and Poland, and was banned from uniting with German-settled regions of Austria. The German Revolution 
Title: World War I
Content:  Some of the first clashes of the war involved British, French, and German colonial forces in Africa. On 6–7 August, French and British troops invaded the German protectorate of Togoland and Kamerun. On 10 August, German forces in South-West Africa attacked South Africa; sporadic and fierce fighting continued for the rest of the war. The German colonial forces in German East Africa, led by Colonel Paul von Lettow-Vorbeck, fought a guerrilla warfare campaign during World WarI and only surrendered two weeks after the armistice took effect in Europe.
Title: International relations of the Great Powers (1814–1919)
Content:   The First World War was a global conflict that lasted from 1914 to 1918. It saw the Central Powers (Germany and Austria-Hungary, later joined by the Ottoman Empire and Bulgaria), fighting the "Entente" or "Allied" powers, led by Britain, Russia and France from 1914, who were later joined by Italy in 1915, and other countries such as Romania in 1916. The United States, initially neutral, tried to broker a settlement but in April, 1917, it declared war on Germany. The U.S. cooperated with the Allies but did not formally join them, and it negotiated peace separately. Despite overcoming Romania in 1916 (although Romania continued to fight until May 1918, later rejoining the war on November 1918) and Russia in March 1918, the Central Powers collapsed in November, 1918; and Germany accepted an "armistice" that in practice was a total surrender. Much of the diplomatic efforts of the

Germany fought against Russia in World War I (1914–1918). Relations were warm in the 1920s, very cold in the 1930s, friendly in 1939–41, and then turned into war to the death in 1941–45. In the 1920s both countries co-operated with each other in trade and (secretly) in military affairs. Hostilities escalated in the 1930s as the Fascists sponsored by Berlin and the Communists sponsored by Moscow fought each other across the world, most famously in the Spanish Civil War (1936–39). In a stunning turnabout in August 1939, both countries came to an agreement, and divided up the previously independent

The full realisation of Mittelafrika depended on a German victory in the European theatre of the First World War, where Britain would be forced to negotiate and cede its colony of Rhodesia to Germany when faced with a German-dominated continent across the English Channel. In the course of the actual war, German aspirations in Mittelafrika were never matched by events in the African theatre of the First World War. The German colonies were at very different levels of defence and troop strength when the war began in Europe, and were not in a position to fight a war due to a lack of materiel.

Under the terms of the Treaty of Versailles, the German and Austro-Hungarian Empires were both dissolved and partitioned, resulting in millions of Germans becoming ethnic minorities in other countries. The monarchichal rulers of the German states, including the German emperor Wilhelm II, were overthrown in the November Revolution which led to the establishment of the Weimar Republic.

Title: Germany–Soviet Union relations, 1918–1941
Content:  The outcome of the First World War was disastrous for both the Weimar Republic and the Russian Soviet Federative Socialist Republic. During the war, the Bolsheviks struggled for survival, and Vladimir Lenin had no option except to recognize the independence of Finland, Estonia, Latvia, Lithuania, Poland, and Ukraine. Moreover, facing a German military advance, Lenin and Leon Trotsky were forced to enter into the Treaty of Brest-Litovsk, which ceded large swathes of western Russian territory to the German Empire. On 11 November 1918, the Germans signed an armistice with the Allies, ending the First World War on the Western Front. After Germany's
