South Korea historical timeline

Chronology

668 Silla unifies the peninsula after centuries of contest between three kingdoms — Goguryeo, Baekje and Silla. Gyeongju was Silla's capital and is the reason a provincial city in the south-east holds more of Korea's early heritage than Seoul does.
1234 Movable metal type is produced in Korea, two centuries before Gutenberg. It belongs to the Goryeo dynasty, which also gave the country its English name, and it is the first of two Goryeo achievements a visitor can still go and look at.
13th century The Tripitaka Koreana: the Buddhist canon carved onto 81,352 wooden printing blocks during the Goryeo period, now held at the temple of Haeinsa in South Gyeongsang province. It contains 1,496 titles in 6,568 books, 81,258 pages and 52,330,152 characters; stacked, the blocks would stand almost as high as Paektu Mountain, and lined up they would run 60 kilometres and weigh 280 tons. They are in pristine condition without warping after more than 750 years. The original set had been destroyed by fire during the Mongol invasion, which is why this one was carved.
1392 The Joseon dynasty takes over and runs a Confucian state for five hundred years. The palaces in Seoul, the civil-service examination culture, the social hierarchy that still shapes Korean speech levels and the architecture of the hanok all belong to this dynasty rather than to anything older.
1443 King Sejong the Great introduces Hangul to his court in the twelfth month of 1443, and it is officially published in 1446 in the Hunminjeongeum. Hanja was poorly suited to Korean and its difficulty contributed to high illiteracy; Hangul was designed so that ordinary people could read and write. It is one of very few writing systems in the world whose inventor, date and design principles are all known, and it has its own public holiday.
1592 The Imjin War: two Japanese invasions launched by Toyotomi Hideyoshi to conquer Korea, an initial invasion in 1592, a truce in 1596, and a second in 1597. Japan quickly occupied large parts of the country, but reinforcements from Ming China and the disruption of Japanese supply fleets by the Joseon navy forced a withdrawal from the northern provinces; the war ended in 1598 after Hideyoshi's death and a Japanese defeat at the Battle of Noryang. Admiral Yi Sun-sin is the national figure this produced, and the turtle-ship replicas in Korean harbours are about him.
1910 Japan formally annexes Korea by the treaty of 22 August 1910, proclaimed and effective on 29 August, following the 1905 treaty that made Korea a protectorate and the 1907 treaty that stripped it of internal administration. Japanese rule lasted until 1945 and suppressed the language and the culture, which is why Hangul carries the weight it does and why the restored palace buildings in Seoul are restorations.
1945 The division of Korea begins at the end of the Second World War on 2 September 1945, with a Soviet occupation zone in the north and a US occupation zone in the south, and the 38th parallel as the dividing line. This was done by the occupying powers, not by Koreans, and it is the single fact that explains everything after it.
1948 After the UN fails to produce an outcome acceptable to the Soviet Union, UN-supervised elections are held in the US-occupied south only, and the Republic of Korea is established on 15 August 1948, with the Democratic People's Republic established in the north the same year. Two states where there had been one, three years after the war ended.
1950 The Korean War runs from 25 June 1950 to 27 July 1953, beginning with the North Korean invasion of the South. It caused around one million military deaths and an estimated 1.5 to 3 million civilian deaths. Combat ended with the Armistice Agreement, which created a demilitarised zone four kilometres wide along the front line with a Joint Security Area at Panmunjom. No formal peace treaty has ever been signed — the DMZ a visitor tours is a live front, not a monument.
1980 The Gwangju Uprising, the May 18 Democratisation Movement: student-led demonstrations against the coup by which Chun Doo-hwan had taken power in December 1979. It began when Chonnam National University students demonstrating against martial law were fired upon, beaten and tortured by soldiers. The government claimed 165 people were killed; current scholarship estimates between 600 and 2,300. Chun's military government labelled it a riot. Gwangju has the national cemetery and the memorial, and the event is the founding story of South Korean democracy.
1987 The June Democratic Struggle: nationwide pro-democracy protests from 10 to 29 June 1987, triggered when Chun announced the selection of his ally Roh Tae-woo as the next president — seen as a final affront to the long-delayed revision of the constitution to allow direct presidential elections. The demonstrations forced the government to hold direct elections and institute other democratic reforms, establishing the Sixth Republic, which is the present-day government. South Korean democracy is younger than the Seoul subway, whose first line opened in 1974.
1988 Seoul hosts the Olympic Games, the year after the June Struggle. The Games were the country's introduction to the world as something other than a war or a dictatorship, and the infrastructure built for them — the subway extensions, the riverside parks along the Han — is still the shape of the city.
1997 The Asian financial crisis and the IMF programme that followed. Koreans call it the IMF crisis and date a great deal of modern social change from it, including the end of lifetime employment; it is the economic reference point the way 1987 is the political one.
2013 Kimjang, the communal autumn making of kimchi, is listed as UNESCO Intangible Cultural Heritage in December 2013 and as the 133rd Korean Intangible Cultural Property. It is the clearest example of the deliberate turn that made cultural production a Korean export industry — the same policy that produced the film and music industries a visitor now arrives already knowing.
2018 Pyeongchang hosts the Winter Olympics, thirty years after Seoul and thirty-one years after the direct presidential elections of 1987. The two Games fall either side of the whole of South Korean democracy.
