Introduction
1 fieldBackground
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 5 th 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 7 th century (688). Following the collapse of Silla in the 9 th 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 20 th 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.

Economic overview
After emerging from the 1950-53 war with North Korea, South Korea emerged as one of the 20th century’s most remarkable economic success stories, becoming a developed, globally connected, high-technology society within decades. In the 1960s, GDP per capita was comparable with levels in the poorest countries in the world. In 2004, South Korea's GDP surpassed one trillion dollars.
Beginning in the 1960s under President PARK Chung-hee, the government promoted the import of raw materials and technology, encouraged saving and investment over consumption, kept wages low, and directed resources to export-oriented industries that remain important to the economy to this day.
Growth surged under these policies, and frequently reached double-digits in the 1960s and 1970s. Growth gradually moderated in the 1990s as the economy matured, but remained strong enough to propel South Korea into the ranks of the advanced economies of the OECD by 1997. These policies also led to the emergence of family-owned chaebol conglomerates such as Daewoo, Hyundai, and Samsung, which retained their dominant positions even as the government loosened its grip on the economy amid the political changes of the 1980s and 1990s.
The Asian financial crisis of 1997-98 hit South Korea’s companies hard because of their excessive reliance on short-term borrowing, and GDP ultimately plunged by 7% in 1998. South Korea tackled difficult economic reforms following the crisis, including restructuring some chaebols, increasing labor market flexibility, and opening up to more foreign investment and imports.
These steps lead to a relatively rapid economic recovery. South Korea also began expanding its network of free trade agreements to help bolster exports, and has since implemented 16 free trade agreements covering 58 countries—including the United State and China—that collectively cover more than three-quarters of global GDP.
In 2017, the election of President MOON Jae-in brought a surge in consumer confidence, in part, because of his successful efforts to increase wages and government spending. These factors combined with an uptick in export growth to drive real GDP growth to more than 3%, despite disruptions in South Korea’s trade with China over the deployment of a US missile defense system in South Korea.
In 2018 and beyond, South Korea will contend with gradually slowing economic growth - in the 2-3% range - not uncommon for advanced economies. This could be partially offset by efforts to address challenges arising from its rapidly aging population, inflexible labor market, continued dominance of the chaebols, and heavy reliance on exports rather than domestic consumption.
Socioeconomic problems also persist, and include rising inequality, poverty among the elderly, high youth unemployment, long working hours, low worker productivity, and corruption.

the 1953 US-South Korea Mutual Defense Treaty is a cornerstone of South Korea’s security; the Treaty committed the US to provide assistance in the event of an attack, particularly from North Korea; in addition, the Treaty gave the US permission to station land, air, and sea forces in and about the territory of South Korea as determined by mutual agreement; as of 2021, the US maintained approximately 28,000 military personnel in the country
the South Korean military has assisted the US in conflicts in Afghanistan (5,000 troops; 2001-2014), Iraq (20,000 troops; 2003-2008), and Vietnam (325,000 troops; 1964-1973)
South Korea has Major Non-NATO Ally (MNNA) status with the US; MNNA is a designation under US law that provides foreign partners with certain benefits in the areas of defense trade and security cooperation; while MNNA status provides military and economic privileges, it does not entail any security commitments
in 2016, South Korea concluded an agreement with the European Union for participation in EU Common Security and Defense Policy (CSDP) missions and operations, such as the EU Naval Force Somalia – Operation Atalanta, which protects maritime shipping and conducts counter-piracy operations off the coast of East Africa
South Korea has been engaged with NATO through dialogue and security cooperation since 2005 and is considered by NATO to be a global partner; it has participated in NATO-led missions and exercises, including leading an integrated civilian-military reconstruction team in Afghanistan as part of the NATO-led International Security Assistance Force, 2010-2013; it has also cooperated with NATO in countering the threat of piracy in the Gulf of Aden by providing naval vessels as escorts
