World War I
10 documented theories filed under this subject.
- The "Dreadnought" HoaxOn 24 February 1910 the First Lord of the Admiralty told the House of Commons that "a number of persons" disguised as Abyssinians had visited one of His Majesty's ships. The ship was HMS Dreadnought, and the party, led by the prankster Horace de Vere Cole, included the future Virginia Woolf. They had been admitted on a forged Foreign Office telegram. Four years later Winston Churchill ordered a "dummy fleet" of merchant ships disguised in wood and canvas as battleships. Placed side by side, the two episodes produced a theory that British sea power in the dreadnought era was partly theatre.
- The WWI ConspiracyColonel House's own diary records him and King George V discussing the sinking of the Lusitania on the morning it happened. James Corbett's 2018 documentary The WWI Conspiracy builds on documents like that one: the Rhodes wills, Edward Grey's secret staff talks with France, and the October 1915 letter in which Woodrow Wilson added the word "probably" to a promise that America would join the war. From them it argues that a British imperial network founded by Cecil Rhodes engineered the First World War.
- The "Sisson Documents"The Sisson Documents were a set of papers publicized in 1918 that purported to prove Vladimir Lenin, Leon Trotsky, and other Bolshevik leaders were acting as paid agents of the German General Staff during World War I. The documents were obtained by Edgar Sisson, a representative of the U.S. Committee on Public Information, and circulated in the United States as evidence of a German-Bolshevik conspiracy. They were widely cited in anti-Bolshevik and anti-radical propaganda during the closing phase of the war and the early Red Scare. Later scholarly analysis, most notably George F. Kennan’s 1956 study, concluded that the documents were forgeries, though the wider historical question of German assistance to revolutionary actors in Russia remained separate from the authenticity of the documents themselves.
- The British and the German Royalty PactThe British and the German Royalty Pact was the belief that the First World War, and later political arrangements around it, were driven or constrained by a hidden understanding among Europe’s interrelated royal families. The theory treated the war not as a clash of states alone but as a dynastic family conflict managed from behind the scenes.
- The "British" Royals are GermanThis theory was unusual because its central factual claim was true: the British royal house was, by dynastic descent, the House of Saxe-Coburg and Gotha until George V changed the family name to Windsor in 1917. What made it function as a conspiracy theory was not the genealogy itself, but the implication that Britain was secretly ruled by “Germans” during a war against Germany. In that context, a dynastic fact became a political accusation of hidden foreignness and divided loyalty.
- The "Passport" TotalitarianismThis theory held that wartime passport controls were not temporary emergency measures but the beginning of a permanent regime in which states would own, mark, and track their populations. It developed during World War I, when governments that had previously tolerated freer movement imposed tighter identity and border controls in the name of security. In conspiratorial and libertarian language, the passport was not just a travel paper but a token of political possession.
- The "Henry Ford" Peace Ship PlotThis theory claimed that Henry Ford’s 1915 Peace Ship mission was not a naïve or idealistic antiwar intervention, but a covert effort to negotiate the foundations of a private industrial order above governments. The actual Peace Ship expedition was a real and widely publicized attempt by Ford to bring peace activists to Europe and encourage negotiations among neutral and belligerent powers. The conspiracy version transforms that mission into a private diplomacy project aimed at creating an “industrial empire” managed by business rather than states.
- The Zimmerman Telegram "Hoax"This theory held that the Zimmermann Telegram published in 1917 was not an authentic German diplomatic message but a British forgery released to push the United States into the First World War. The suspicion emerged immediately because the message reached the American public through British intelligence at a moment of high tension, and because many Americans wished to remain out of the European war. Although early forgery claims circulated widely, the message was quickly reinforced by diplomatic evidence and by Arthur Zimmermann’s own public confirmation that the telegram was genuine.
- The "Hidden Hand" (The Milner Group)This theory argues that Lord Alfred Milner’s circle, often identified with the Round Table movement or the so-called Milner Group, acted as a secret imperial network that pushed Britain into the First World War in order to consolidate the British Empire and redesign global politics. The theory draws on a real and documented set of relationships among imperial thinkers, administrators, editors, and policy advocates associated with Milner and Round Table circles. In conspiratorial form, those networks are treated not merely as influential but as covert architects of the war itself.
- The German "Corpse Factory"This theory claimed that Germany had established facilities near the Western Front where the bodies of dead soldiers were rendered into usable materials such as soap, glycerine, oils, lubricants, or explosives. The story became one of the most notorious atrocity narratives of the First World War. It was sustained by rumor, propaganda, mistranslation, and the wider wartime expectation that extreme reports about enemy conduct were inherently plausible. Later investigations and official statements treated the story as false, but its cultural afterlife remained significant.
- The Angels of MonsThis theory holds that supernatural protectors—most commonly described as angels, shining beings, or the ghostly bowmen of Agincourt—appeared above or near the British Expeditionary Force during the retreat from Mons in August 1914 and helped save it from destruction. The legend became one of the best-known supernatural stories of the First World War. Its historical development is closely tied to wartime morale, religious language, grief culture, and the circulation of Arthur Machen’s fictional story “The Bowmen,” which many readers later treated as eyewitness truth.
