Write a realistic, sensible, plausible and alternate history scenario in the form of a historical documentary book chapter set in the world of the alternate historical scenario with no references to this being an alternate history scenario or to the real world timeline at all for the Code Geass anime, manga, video game, visual novel, light novel and radio drama franchise, in which the Imjin Wars of May 23, 1592 – December 16, 1598 launched by the Ashikaga shogunate de-facto lead by Toyotomi Hideyoshi-ruled feudal Japan against the satellite state and tributary kingdom of Great Joeson ruled by the partially Han Chinese Korean House of Jeonju Yi in Korea and the  Han Chinese Imperial House of Zhu-ruled Ming dynasty ruling over both Han China and Cantonia results in a victory for the Japanese due to the death of Korean naval commander Yi-Seong-gye and Korea being absorbed into Japan as the newest province of feudal Japan, even though the Ashikaga shogunate doesn't push on with its conquests due to the death of Hideyoshi 18 September 1598 and the subsequent establishment of the Tokugawa shogunate by Tokugawa Ieyasu on On March 24, 1603. The Great Ming is weakened by these conquests and so when the Mongoloid Jurchen tribes of Greater Manchuria [Manchuria and Outer Manchuria] start their conquest of Han China from Manchuria in 1636, [the Jurchens] proclaiming the Manchu-Imperial House of Aisin-Gioro Great Qing Empire in 1661 after [the Jurchens] conquering East Turkestan, Greater Mongolia and Tibet, although they [the Jurchens] are [the Jurchens] bogged down in Central China due to heavy Ming resistance. The Ming eventually conquer the nations of Indochina, Vietnam, Cambodia and Laos and [the Ming] wipe out the Vietnamese, Cambodians and Laotians along with the Cantonians, [the Ming] absorbing the survivors into what becomes known as the Southern Ming. The Japanese manage to seize the partially Japanese  Zheng dynasty/Royal House of Koxinga-Kingdom of Tungning-ruled Taiwan and the Pengu Islands instead of the Qing and [the Japanese] also seize Sahlakin and the Kurils due to their [the Japanese's] immense amount of Sakuradite [Code Geass]. A Cold War akin to the ancient Three Kingdoms period begins with the Japanese ruling the waves, the Qing dominating the land and the rump Ming state dominating trade. Due to the constant warfare between the rump Ming state and the Qing Empire, Japan never sees the need to modernize and the Tokugawa shogunate survives post 1868 as the German Hanovers through George II seize control over a post-1500s surviving Tudor UK in exile in Canada and Jamaica in 1758 after a earlier French revolution leads Napoleon successfully invades the British Isles, [the Hanovers] becoming the first Emperors of what will become the Holy Britannian Empire [Code Geass]. During the American revolution, the Brittanians hand over the rebellious 13 colonies to the Swiss-Austrian House of Hapsburg-ruled Holy Roman Empire in exchange for Austrian help against the fascist regime of Revolutionary France and [the Brittanians] conquer the Indian subcontinent, [the Brittanians] forming the British Raj in the Indian Subcontinent and British East Asia in Malyasia, Australia and New Zealand. When the Hanover monarch known in real life as Queen Victoria I dies in January 22, 1901 after [Victoria] presiding over the dissolution of African chattel slavery, a cease fire to the American Civil War that resulting in the Democrat Party-ruled slave states of the Confederacy being absorbed into British North America [Canada], a dynastic union between the Hanovers and the Portugese House of Brazanga-ruled Empire of Brazil that saw the Empire of Brazil absorbed into Brittania, and the Franco-German Wars turning into a WW1 equivalent with the German House of Hohenzollern-ruled German Empire managing to call in the rump state of the Holy Roman Empire, the Hapsburg-ruled Austria-Hungarian Empire, against Napoleon III's French Empire and [Germany and Austria-Hungary] enforce measures akin to the Treaty of Versailes upon the French, leading to French resentment and the establishment of the fascist regime known as the Third French Republic in France, with the Catholic side-branch of the German main house of the real-life British royal family, the  House of Saxe-Coburg and Gotha seizing power and using the oppurtunity to take Greater Bulgaria from the Ottomans, forming the Third Bulgarian Tsardom and absorbing the British Empire in exile into the Third Bulgarian Czardom, proclaiming the restoration of the Eastern Roman rump state wrongly called Byzantium through this Greater Bulgarian Empire under its first Emperor, Ferdinand I. This Greater Bulgaria still joins the Central Powers but the Central Powers crush the Entente and [the Central Powers] enforce a "denazification" equivalent to France and a "defascification" equivalent to the British Isles. The descendants of Victoria's son Edward VII are angry that they did not become the Brittanian imperial family and so a bloody civil war between them and the current Brittanian imperial family results, known as the "Emblem of Blood". Meanwhile the Germans and Austria-Hungarians united Europe under the banner of Europa United [Code Geass] or Euro-Universe, with the Brittanians seizing Russia using the Saxe-Gotha's familial ties to the Romanovs as an excuseEmperor Charles zi Brittania [Code Geass] emerges from the Emblem of Blood to lead Brittania in the conquest of a Soviet Union ruled by Trotsky , the solidification of the British Raj and the unification of Greater China under the Ming rump state after the collapse of the Qing to the Xinhai Revolution of 1912, [Charles] giving the Ming Siberian and Central Asian territories owned by the Yuan dynasty and Tang dynasty and [Charles] taking the Chinese Empress as one of his [Charles'] wives to have a powerful ally. In 1951 AD, work on the humanoid house sized war machines known as Knightmare Frames [Code Geass] by the Ashford family [Code Geass] begins with the Ashford's main ally and Charles' empress consort, Marianne [Code Geass] finding them [the Knightmare Frames] to be very useful. In 1954 AD Marianne is supposedly killed by American freedom fighters who want the Brittanian occupied Southern States back and Charles sends his [Charles'] and Marianne's children, the current Brittanian Crown Prince and Charles' favored heir Lelouch vi Brittania [Code Geass] and his [Lelouch's] younger sister and current Brittanian Crown Princess, Nunnally vi Brittania [Code Geass] to the surviving Tokugawa shogunate as protection only for them [Lelouch and Nunnally] to mysterious disappear while in Japan, causing Charles to declare war on the surviving Tokugawa shogunate with the approval of the Chinese Federation and starting the events of canon Code Geass.
