The South Korean ferry MV Sewol capsizes and sinks near Jindo Island, killing 304 passengers and crew and leading to widespread criticism of the South Korean government, media, and shipping authorities.

The sinking of MV Sewol (Korean: ; Hanja: ), also called the Sewol ferry disaster, occurred on the morning of 16 April 2014, when the ferry MV Sewol was en route from Incheon towards Jeju in South Korea. The 6,825-ton vessel sent a distress signal from about 2.7 kilometres (1.7 mi; 1.5 nmi) north of Byeongpungdo at 08:58 KST (23:58 UTC, 15 April 2014). Out of 476 passengers and crew, 304 died in the disaster, including around 250 students from Danwon High School (Ansan City). Of the approximately 172 survivors, more than half were rescued by fishing boats and other commercial vessels that arrived at the scene approximately forty minutes before the Korea Coast Guard (KCG).The sinking of Sewol resulted in widespread social and political reaction within South Korea. Many criticized the actions of the ferry's captain and most of the crew. Also criticized were the ferry's operator, Chonghaejin Marine, and the regulators who oversaw its operations, along with the administration of President Park Geun-hye for her response to the disaster and attempts to downplay government culpability, and the KCG for its poor handling of the disaster, and the perceived passivity of the rescue-boat crew on scene. Outrage has also been expressed against the initial false reporting of the disaster by the government and South Korean media, who claimed everyone aboard had been rescued and against the government for prioritizing public image over the lives of its citizens in refusing help from other countries and publicly downplaying the severity of the disaster.On 15 May 2014, the captain and three crew members were charged with murder, while the other eleven members of the crew were indicted for abandoning the ship. An arrest warrant was also issued for Yoo Byung-eun, the owner of Chonghaejin Marine, but he could not be found despite a nationwide manhunt. On 22 July 2014, police revealed that they had established that a dead man found in a field 415 kilometres (258 mi) south of Seoul was Yoo.

South Korea, officially the Republic of Korea (ROK), is a country in East Asia, constituting the southern part of the Korean Peninsula and sharing a land border with North Korea. Its western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. South Korea has a population of 51 million, of which roughly half live in the Seoul Capital Area, the fifth largest metropolis in the world. Other major cities include Incheon, Busan, and Daegu.

The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Silla and Balhae in the late 7th century, Korea was ruled by the Goryeo dynasty (918–1392) and the Joseon dynasty (1392–1897). The succeeding Korean Empire was annexed in 1910 into the Empire of Japan. Japanese rule ended following the former's surrender in World War II, after which Korea was divided into two zones; a northern zone occupied by the Soviet Union and a southern zone occupied by the United States. After negotiations on reunification failed, the latter became the Republic of Korea in August 1948 while the former became the socialist Democratic People's Republic of Korea the following month.

In 1950, a North Korean invasion began the Korean War, which saw extensive American-led United Nations intervention in support of the South, while China intervened to support the North, with Soviet assistance. After the war's end in 1953, the country's devastated economy began to soar, recording the fastest rise in average GDP per capita in the world between 1980 and 1990. The June Struggle led to the end of authoritarian rule in 1987 and the country is now considered among the most advanced democracies in Asia, with the highest level of press freedom on the continent.South Korea is a developed country and is ranked as the seventh-highest country on the Human Development Index (HDI) in the Asia and Oceania region. South Korea has one of the highest life expectancies in the world, although it is facing an aging population and a declining fertility rate. Its economy ranks as the world's tenth-largest by nominal GDP. Its citizens enjoy one of the world's fastest Internet connection speeds and the densest high-speed railway network. The country is the world's fifth-largest exporter and eighth-largest importer. Its armed forces is ranked as one of the world's strongest militaries and is the world's third-largest standing army by military and paramilitary personnel. Since the 21st century, South Korea has been renowned for its globally influential pop culture, particularly in music (K-pop), TV dramas and cinema, a phenomenon referred to as the Korean Wave. It is a member of the OECD's Development Assistance Committee, the G20, and the Paris Club.
