The disarray and blatant corruption in the Korean government, particularly in the three main areas of revenues –
land tax, military service, and the state granary system – weighed heavily on the Korean peasantry. Of special note is the corruption of the local functionaries (
Hyangi) who could purchase an appointment as administrators and cloak their predations on the farmers with an aura of officialdom.
Yangban families, formerly well-respected for their status as a noble class, were increasingly seen as little more than commoners who were unwilling to meet their responsibilities to their communities. Faced with increasing corruption in the government,
brigandage of the disenfranchised (such as the mounted fire brigands, or
Hwajok, and the boat-borne water brigands or
Sujok) as well as abuse by the military, many poor villagers sought to pool their resources such as land, tools, and production skills in order to survive. Despite the government abolishing slavery and burning the records in 1801, increasing numbers of peasants and farmers become involved in "mutual assistance associations". Institutions such as the Catholic and Protestant missions, with the egalitarian nature of their teachings garnered followings among the Yangban, though commonly in the more urban areas. Arguably of greater influence were the religious teachings of
Choe Je-u, (최제우, 崔濟愚, 1824–1864) called
Donghak or "Eastern Learning" which became especially popular in rural areas. Themes of exclusionism (of foreign influences),
nationalism, salvation, and social consciousness were promoted to allow illiterate farmers to understand the concepts and accept them more readily. Choi, like many Koreans, was alarmed by the intrusion of
Christianity and the Anglo-French occupation of Beijing during the
Second Opium War. He believed that the best way to counter foreign influence in Korea was to introduce democratic and human rights reforms internally. Nationalism and social reform struck a chord among the peasant guerrillas, and
Donghak spread all across Korea. Progressive revolutionaries organized the peasants into a cohesive structure. Arrested in 1863 following the Chinju Uprising led by Yu Kye-cheun, Choi was charged with "misleading the people and sowing discord in society". Choi was beheaded in 1864, sending many of his followers into hiding in the mountains and leaving the Korean populace to continue to suffer.
King Gojong (r. 1864–1907), enthroned at the age of twelve, succeeded
King Cheolchong (r. 1849 – 1863). King Gojong's father,
Heungseon Daewongun (Yi Ha-Ung; 1820–1898), ruled as the
de facto regent and inaugurated far-ranging reform to strengthen the central administration. Among his targeted reforms was addressing the inherited rule by a few elite ruling families by the adoption of a merit system for official appointments. In addition,
Seowon (private academies), which threatened to develop a parallel system to the corrupt government and enjoyed special privileges and large land-holdings, were repressed through taxes despite bitter opposition from Confucian scholars. The decision to rebuild palace buildings and finance it through additional levies on the population caused
Heungseon Daewongun's attempted reforms to antagonize the three largest constituencies supporting the government: the ruling elite, the Confucian scholars, and the general population.
Heungseon Daewongun was impeached in 1873 and forced into retirement by the supporters of
Empress Myeongseong. On 27 February 1876, the
Japan–Korea Treaty of 1876, also known in Japan as the Japanese-Korean Treaty of Amity (, ) was signed. It was designed to open up Korea to Japanese trade, and the rights granted to Japan under the treaty were similar to those granted to European powers in Japan following the visit of
Commodore Matthew Perry in 1854. However, the treaty ended Korea's status as a protectorate of China,
forced open three Korean ports to Japanese trade, granted
extraterritorial rights to Japanese citizens, and was an
unequal treaty signed under
duress of the
Unyo Incident of 1875 (
gunboat diplomacy). Daewongun remained opposed to any concessions to Japan or the Western Europeans, helped organize the mutiny of 1882
Imo Incident, an anti-Japanese outbreak against the Empress and her allies. Motivated by resentment of the preferential treatment given to newly trained troops, Daewongun's forces, or "old military", killed Japanese training cadre and attacked the Japanese
legation. policemen, students and some Min clan members were also killed during the incident. Daewongun was restored to power briefly, only to be forcibly taken to China by Chinese troops dispatched to
Seoul to prevent further disorder. In August 1882, the Treaty of Chemulpo (
Japan–Korea Treaty of 1882) indemnified the families of the Japanese victims, paid reparation to the Japanese government in the amount of 500,000 yen and allowed a company of Japanese guards to be stationed at the Japanese legation in Seoul. The struggle between Heungseon Daewongun's followers and those of Empress Myeongseong was further complicated by competition from a Korean independence faction known as the
Progressive Party (Kaehwadang) as well as Conservative faction. While the former sought Japan's support, the latter sought China's support. On 4 December 1884, the Korean independence group, assisted by the Japanese, attempted a coup (
Kapsin Chongbyon; Coup d'État of 1884) and established a pro-Japanese government under the reigning king, dedicated to the independence of Korea from Chinese suzerainty. However, this proved to be short-lived as conservative Korean officials requested the help of Chinese forces stationed in Korea. The coup was put down by Chinese troops, and a Korean mob killed both Japanese officers and Japanese residents in retaliation. Some leaders of the independence faction, including
Kim Okgyun, fled to Japan, while others were executed. == Donghak revolution, and first Sino-Japanese war, 1894 ==
