South Korea, officially the Republic of Korea (ROK), is a country in East Asia. It constitutes the southern half of the Korean Peninsula and borders North Korea along the Korean Demilitarized Zone, with the Yellow Sea to the west and the Sea of Japan to the east. Like North Korea, South Korea claims to be the sole legitimate government of the entire peninsula and adjacent islands. It has a population of about 52 million, of which half live in the Seoul Metropolitan Area, the ninth most populous metropolitan area in the world; other major cities include Busan, Daegu, and Incheon.
The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early seventh century BC. From the mid first century BC, various polities consolidated into the rival kingdoms of Goguryeo, Baekje, and Silla. The lattermost eventually unified most of the peninsula for the first time in the late seventh century AD, while Balhae succeeded Goguryeo in the north. The Goryeo dynasty (918–1392) achieved lasting unification and established the basis for the modern Korean identity. The subsequent Joseon dynasty (1392–1897) generated cultural, economic, and scientific achievements and also established isolationism starting from the mid-17th century. The succeeding Korean Empire (1897–1910) sought modernization and reform but was annexed in 1910 into the Empire of Japan. Japanese rule ended following Japan's surrender in World War II, after which Korea was divided into two zones: the Soviet-occupied northern zone and the United States-occupied southern zone. After negotiations on reunification failed, the southern zone became the Republic of Korea in August 1948, while the northern zone became the communist Democratic People's Republic of Korea the following month.
In 1950, a North Korean invasion triggered the Korean War, one of the first major proxy conflicts of the Cold War, which saw extensive fighting involving the American-led United Nations Command and the Soviet-backed People's Volunteer Army from China. The war ended in 1953 with an armistice and left three million Koreans dead and the economy in ruins; due to the lack of a peace treaty, the Korean conflict is still ongoing. South Korea endured a series of dictatorships punctuated by coups, revolutions, and violent uprisings, but also experienced a soaring economy and one of the fastest rises in average GDP per capita, leading to its emergence as one of the Four Asian Tigers. The June Democratic Struggle of 1987 ended authoritarian rule and led to the establishment of the current Sixth Republic. (Full article...)

Japan–South Korea relations (Japanese: 日韓関係, romanized: Nikkan kankei; Korean: 한일관계; RR: Hanil gwangye) are the diplomatic relations between Japan and the Republic of Korea. As the Sea of Japan and the Korea Strait geographically separate the two nations, political interactions date back from the 6th century when the kingdom of Baekje (which encompassed much of present-day South Korea) officially established relations with the Yamato Kingship of Japan. During the ancient era, the southern region of the Korean Peninsula served as the closest port for economic trade and cultural exchange between the Japanese archipelago and mainland Asia. Such relations would continue by the late 19th century when both Japan and Korea underwent modernisation from Western powers up until 1910, when Korea became a colony of Japan.
Shortly after gaining independence from the Japanese surrender at the end of World War II in 1945, Korea was divided into two states. During the Korean War, Japan took part in aiding South Korea by providing military supplies to US and UN forces against the communist-led North Korea.
Japan and South Korea formally established diplomatic relations in December 1965, under the Treaty on Basic Relations Between Japan and the Republic of Korea, with Japan recognising South Korea as the only legitimate government in the Korean Peninsula. (Full article...)

The Third Battle of Seoul was a battle of the Korean War, which took place from December 31, 1950, to January 7, 1951, around the South Korean capital of Seoul. It is also known as the Chinese New Year's Offensive, the January–Fourth Retreat (Korean: 1·4 후퇴) or the Third Phase Campaign Western Sector (Chinese: 第三次战役西线; pinyin: Dì Sān Cì Zhàn Yì Xī Xiàn).
In the aftermath of the major Chinese People's Volunteer Army (PVA) victory at the Battle of the Ch'ongch'on River, the United Nations Command (UN) started to contemplate the possibility of evacuation from the Korean Peninsula. Chinese Communist Party chairman Mao Zedong ordered the Chinese People's Volunteer Army to cross the 38th Parallel in an effort to pressure the UN forces to withdraw from South Korea.
On December 31, 1950, the Chinese 13th Army attacked the Republic of Korea Army (ROK)'s 1st, 2nd, 5th and 6th Infantry Divisions along the 38th Parallel, breaching UN defenses at the Imjin River, Hantan River, Gapyeong and Chuncheon in the process. To prevent the PVA forces from overwhelming the defenders, the US Eighth Army now under the command of Lieutenant General Matthew B. Ridgway evacuated Seoul on January 3, 1951. (Full article...)
