The first recorded kingdom (Choson) on the Korean Peninsula dates from approximately 2300 B.C. Over the subsequent centuries, three main kingdoms – Kogoryo, Paekche, and Silla – were established on the Peninsula.  By the 5th century A.D., Kogoryo emerged as the most powerful, with control over much of the Peninsula, as well as part of Manchuria (modern-day northeast China).  However, Silla allied with the Chinese to create the first unified Korean state in the late 7th century (688).  Following the collapse of Silla in the 9th century, Korea was unified under the Koryo (Goryeo; 918-1392) and the Chosen (Joseon; 1392-1910) dynasties. Korea became the object of intense imperialistic rivalry between the Chinese (its traditional benefactor), Japanese, and Russian empires in the latter half of the 19th and early 20th centuries. Following the Sino-Japanese War (1894-95) and the Russo-Japanese War (1904-1905), Korea was occupied by Imperial Japan. In 1910, Tokyo formally annexed the entire Peninsula. Korea regained its independence following Japan’s surrender to the US and its allies in 1945. After World War II, a democratic government (Republic of Korea, ROK) was set up in the southern half of the Korean Peninsula while a communist-style government was installed in the north (North Korea; aka Democratic People’s Republic of Korea, DPRK). During the Korean War (1950-53), US troops and UN forces fought alongside ROK soldiers to defend South Korea from a North Korea invasion supported by communist China and the Soviet Union. A 1953 armistice split the Peninsula along a demilitarized zone at about the 38th parallel. PARK Chung-hee took over leadership of the country in a 1961 coup. During his regime from 1961 to 1979, South Korea achieved rapid economic growth, with per capita income rising to roughly 17 times the level of North Korea in 1979. Park was assassinated in 1979, and subsequent years were marked by political turmoil and continued authoritarian rule as the country’s pro-democracy movement grew. South Korea held its first free presidential election under a revised democratic constitution in 1987, with former South Korean Army general ROH Tae-woo winning a close race. In 1993, KIM Young-sam (1993-98) became the first civilian president of South Korea’s new democratic era. President KIM Dae-jung (1998-2003) won the Nobel Peace Prize in 2000 for his contributions to South Korean democracy and his “Sunshine Policy” of engagement with North Korea. President PARK Geun-hye, daughter of former South Korean President PARK Chung-hee, took office in February 2013 as South Korea’s first female leader. In December 2016, the National Assembly passed an impeachment motion against President PARK over her alleged involvement in a corruption and influence-peddling scandal, immediately suspending her presidential authorities. The impeachment was upheld in March 2017, triggering an early presidential election in May 2017 won by MOON Jae-in. South Korea hosted the Winter Olympic and Paralympic Games in February 2018, in which North Korea also participated. Discord with North Korea has permeated inter-Korean relations for much of the past decade, highlighted by North Korea’s attacks on a South Korean ship and island in 2010, the exchange of artillery fire across the DMZ in 2015, and multiple nuclear and missile tests in 2016 and 2017. North Korea’s participation in the Winter Olympics, dispatch of a senior delegation to Seoul, and three inter-Korean summits in 2018 appear to have ushered in a temporary period of respite, buoyed by the historic US-North Korea summits in 2018 and 2019. Nevertheless, relations were stagnant in 2020 and 2021.
