The TL deals with the intelligience TL during July crisis. Although in this TL the Assassination of Franz Ferdinand is averted by Austrian Intelligience, preventing the WW1. This results afterwards, the trickery part comes in that officially in peace, yet in covertly, a war went on.A cold war.
This TL would also feature Mata Hari, who, as the underground spy, carried out her carrier. But is arrested in 1919.
Revolution four: Trotskyist DPRK
Revolution One: Change of Dynasty (역성혁명/Yeogseonghyeogmyeong). Yi Sun-sin survived the battle of Noryang. He was conferred the title of 개국공/Gaeguggong, or duke the (re)builder of the nation, making him and his family on par with Silla's Gim Yu-sin in terms of power and prestige. He bore one more son before he died of old age. In the following decades, successive Gaeguggongs (that is, the Yi family) assumed more and more political power. Until and descendant of the admiral assumed the throne in a coup shortly before the Later Jin Invasion of Joseon, in a manner similar to the founding of Joseon Dynasty. A new dynasty was established, called the Daehan Dynasty*. The Daehan allied themselves with the Jurchens (or at least kept neutral in circumstances), thus sparing the country from Later Jin and Qing invasions, even securing some land north of Tumen River. The new Daehan court carried out far-reaching reforms, including abolishing some Yangban privileges, liberating the untouchables, lifting restrictions on Buddhism, introducing new world crops, and combining the land tax with the toll tax to encourage population growth. The military was also reformed along Jurchen and Portuguese lines. As the result of these reforms, the Daehan Dynasty entered a new phase of economic and population growth.
The rise in strength of the Daehan State alarmed the Qing Court, who tried much harder to keep Manchuria populated (as contrasted to its OTL depopulation). A few skirmishes broke out, but Daehan troops held out with the help of their Portuguese drill and weapons.
Revolution Two: Gwangmu Rejuvenation (광무유신/Gwangmuyusin). Born out of a naval tradition, the Daehan Dynasty was initially quite extrovert and mercantile. Korean trade ships traveled back and forth between ports as far as Batavia, Manila, Guangzhou, Tainan and Incheon, which flourished. However, the trade was strictly state-controlled, and subjected to political whims of the Kings. So, although Korea was never as cut-off from the rest of the world as IOTL, it still took a full scale naval defeat on the hands of the French to serve as a wake-up call to alarm the Daehan Dynasty into a full-scale reform. A new prince was effectively hailed as king by revolting peasants in 1866, who were angered by heavy taxes and inspired by egalitarian ideas derived from Catholicism. The revolt was called the 서학/Seohak (Western Learning) Rebellion.
After assuming the throne, the new prince adopted the Era Name Gwangmu, and purged the ranks of the Seohak Rebels who made him King. Reform measures initiated by the King included opening the parliament, westernizing the Army and Navy, total abolition of the Yangban system, building a railroad, reforming the law system, introduction of western industries, and setting up universities. the Gwangmu Rejuvenation happened concurrently to the Meiji Restoration, and the two countries competed against each other, descending into an arms race. To make himself on par with the monarchs of Japan and China, Gwangmu made himself an emperor, and Korea an Empire.
The two nations competed in building up their ironclad fleets, and then for colonies in Southeast Asia. A combined Korea Japanese army marched on Peking in the 1880s, and within decades a reforming Qing build a railroad from Peking to Liaoning, and then to Sinuiju, linking up with Korea railways.
Wisely, Korea chose to invest in its fleets, other than colonizing Manchuria as suggested by some ministers. This contributed to the victory in the Naval Battle of the East Sea in 1905. After the battle, Korea took over Japanese holdings in Luzon, Borneo, Taiwan and Ryukyu.
Revolution Three: The Communist Revolution (
공산혁명/Gongsanhyeogmyeong). After WWI, Korea sent an army into Russian Siberia. The army was heavily influenced by communist ideas, and had to be pulled back to Korea in batches, which only exposed more men to revolutionary ideas. Back then, Korea was a country suffering under the full impact of industrial revolution, with workers living in slums and working up to 18 hours a day. Communist officers tried a coup in 1922, which failed.
Revolution four: Trotskyist DPRK In 1927, Leon Trotsky fled to Korea, he was given a grand reception, by a government hoping to discredit the Bolsheviks by exposing its infighting, and then sent off to Mexico, where he was murdered as per OTL. However, this made it fashionable for Korea radicals to name their own groups "Trotskyites", which distanced themselves from Russia and Stalinism. Two years later, it's the Great Depression, and such groups sprung up like wild fire.
The government tried to distract internal discords by starting island disputes and colonial conflicts with Japan, this only backfired. in 1937, Korean and Japanese troops fighting in Mindanao broke a truce with each other, drank wine, singing revolutionary songs together (
Japanese,
Korean). In high spirit, Some junior Japanese officers declared a "Japanese People's Republic" while Korean officers declared a "Democratic People's Republic of Korea". Prime minister Syngman Rhee was forced to sent tanks to Mindanao and rotated troops back to Korea. However, communist ideas were far more widespread than the authorities were willing to admit.
In 1940, a communist crowd gathered in front of Gwanghwamun. Facing them, were the tank brigade lead by a zealot right-wing former Yangban officer determined to defend the interest of the rich, named Kim Il Sung. What would happen next?
