full_context: Document 1: Korean War: Korea was ruled by Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Japan and—by agreement with the United States—occupied Korea north of the 38th parallel. U.S. forces subsequently occupied the south and Japan surrendered. By 1948, two separate governments had been set up. Both governments claimed to be the legitimate government of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union and China—invaded South Korea on 25 June 1950. On that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83: Complaint of aggression upon the Republic of Korea and decided the formation and dispatch of the UN Forces in Korea. Twenty-one countries of the United Nations eventually contributed to the defense of South Korea, with the United States providing 88% of the UN's military personnel.
Document 2: 2018 Winter Olympics: Pyeongchang was elected as the host city in July 2011, during the 123rd IOC Session in Durban, South Africa. This was the first time that South Korea had hosted the Winter Olympics and the second Olympics held in the country overall, after the 1988 Summer Olympics in Seoul. It was the third time that an East Asian country had hosted the Winter Games, after Sapporo (1972) and Nagano (1998), both in Japan. It was also the first of three consecutive Olympics to be held in East Asia, the other two being the 2020 Summer Olympics in Tokyo and the 2022 Winter Olympics in Beijing.
Document 3: Japanese colonial empire: Korea was occupied and declared a Japanese protectorate following the Japan -- Korea Treaty of 1905, and officially annexed in 1910 through the annexation treaty.
Document 4: Japanese war crimes: Outside Japan, different societies use widely different timeframes in defining Japanese war crimes. For example, the annexation of Korea by Japan in 1910 was enforced by the Japanese military, and the Society of Yi Dynasty Korea was switched to the political system of the Empire of Japan. Thus, North and South Korea refer to "Japanese war crimes" as events occurring during the period of Korea under Japanese rule.By comparison, the Western Allies did not come into military conflict with Japan until 1941, and North Americans, Australians, South East Asians and Europeans may consider "Japanese war crimes" to be events that occurred in 1942–1945.Japanese war crimes were not always carried out by ethnic Japanese personnel. A small minority of people in every Asian and Pacific country invaded or occupied by Japan collaborated with the Japanese military, or even served in it, for a wide variety of reasons, such as economic hardship, coercion, or antipathy to other imperialist powers.Japan's sovereignty over Korea and Formosa (Taiwan), in the first half of the 20th century, was recognized by international agreements—the Treaty of Shimonoseki (1895) and the Japan–Korea Annexation Treaty (1910)—and they were considered at the time to be integral parts of the Japanese Empire. Under the international law of today, there is a possibility the Japan-Korea Annexation Treaty was illegal, as the native populations were not consulted, there was armed resistance to Japan's annexations, and war crimes may also have been committed during the civil wars.
Document 5: North Korea at the Olympics: North Korea (Democratic People's Republic of Korea) first participated at the Olympic Games in 1964, appearing only in the Winter Olympic Games that year. Eight years later in 1972, the nation first participated at the Summer Olympic Games.

Document 7: Qing dynasty: In 1884, pro-Japanese Koreans in Seoul led the Gapsin Coup. Tensions between China and Japan rose after China intervened to suppress the uprising. Japanese Prime Minister Itō Hirobumi and Li Hongzhang signed the Convention of Tientsin, an agreement to withdraw troops simultaneously, but the First Sino-Japanese War of 1895 was a military humiliation. The Treaty of Shimonoseki recognized Korean independence and ceded Taiwan and the Pescadores to Japan. The terms might have been harsher, but when Japanese citizen attacked and wounded Li Hongzhang, an international outcry shamed the Japanese into revising them. The original agreement stipulated the cession of Liaodong Peninsula to Japan, but Russia, with its own designs on the territory, along with Germany and France, in what was known as the Triple Intervention, successfully put pressure on the Japanese to abandon the peninsula.
Document 8: Korean War: Korea was considered to be part of the Empire of Japan as an industrialized colony along with Taiwan, and both were part of the Greater East Asia Co-Prosperity Sphere. In 1937, the colonial Governor-General, General Jirō Minami, commanded the attempted cultural assimilation of Korea's 23.5 million people by banning the use and study of Korean language, literature, and culture, to be replaced with that of mandatory use and study of their Japanese counterparts. Starting in 1939, the populace was required to use Japanese names under the Sōshi-kaimei policy. Conscription of Koreans for labor in war industries began in 1939, with as many as 2 million Koreans conscripted into either the Japanese Army or into the Japanese labor force.
Document 9: Korean War: Korea was ruled by Imperial Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Imperial Japan, as a result of an agreement with the United States, and liberated Korea north of the 38th parallel. U.S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments. Both claimed to be the legitimate government of all of Korea, and neither accepted the border as permanent. The conflict escalated into open warfare when North Korean forces -- supported by the Soviet Union and China -- moved into the south on 25 June 1950. On 27 June, the United Nations Security Council authorized the formation and dispatch of UN forces to Korea to repel what was recognized as a North Korean invasion. Twenty - one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UN's military personnel.

Document 14: Korea under Japanese rule: Korea under Japanese rule began with the end of the short - lived Korean Empire in 1910 and ended at the conclusion of World War II in 1945. Japanese rule of Korea was the outcome of a process that began with the Japan -- Korea Treaty of 1876, whereby a complex coalition of the Meiji government, military, and business officials sought to integrate Korea both politically and economically into the Empire of Japan. A major stepping - stone towards the Japanese occupation of Korea was the Japan -- Korea Treaty of 1905, in which the then - Korean Empire was declared a protectorate of Japan. The annexation of Korea by Japan was set up in the Japan -- Korea Treaty of 1910, which was never actually signed by the Korean Regent, Gojong.
