full_context: Document 1: Korean War: The Korean War (in South Korean Hangul: 한국전쟁, Hanja: 韓國戰爭, Hanguk Jeonjaeng, "Korean War"; in North Korean Chosungul: 조국해방전쟁, Joguk Haebang Jeonjaeng, "Fatherland Liberation War"; 25 June 1950 – 27 July 1953)[a] was started when North Korea invaded South Korea. The United Nations, with United States as the principal force, came to aid of South Korea. China, along with assistance from Soviet Union, came to aid of North Korea. The war arose from the division of Korea at the end of World War II and from the global tensions of the Cold War that developed immediately afterwards.
Document 2: Samsung: In 1938, Lee Byung-chul (1910–1987) of a large landowning family in the Uiryeong county moved to nearby Daegu city and founded Samsung Sanghoe (삼성상회, 三星商會). Samsung started out as a small trading company with forty employees located in Su-dong (now Ingyo-dong). It dealt in dried-fish, locally-grown groceries and noodles. The company prospered and Lee moved its head office to Seoul in 1947. When the Korean War broke out, he was forced to leave Seoul. He started a sugar refinery in Busan named Cheil Jedang. In 1954, Lee founded Cheil Mojik and built the plant in Chimsan-dong, Daegu. It was the largest woollen mill ever in the country.Samsung diversified into many different areas. Lee sought to establish Samsung as leader in a wide range of industries. Samsung moved into lines of business such as insurance, securities and retail.

Document 5: Division of Korea: The division of Korea between North and South Korea occurred after World War II, ending the Empire of Japan's 35 - year rule over Korea in 1945. The United States and the Soviet Union each occupied a portion of the peninsula, with the boundary between their zones of control along the 38th parallel.
Document 6: South Korea: On June 25, 1950, North Korea invaded South Korea, sparking the Korean War, the Cold War's first major conflict, which continued until 1953. At the time, the Soviet Union had boycotted the United Nations (UN), thus forfeiting their veto rights. This allowed the UN to intervene in a civil war when it became apparent that the superior North Korean forces would unify the entire country. The Soviet Union and China backed North Korea, with the later participation of millions of Chinese troops. After an ebb and flow that saw both sides almost pushed to the brink of extinction, and massive losses among Korean civilians in both the north and the south, the war eventually reached a stalemate. The 1953 armistice, never signed by South Korea, split the peninsula along the demilitarized zone near the original demarcation line. No peace treaty was ever signed, resulting in the two countries remaining technically at war. Over 1.2 million people died during the Korean War.
Document 7: Korean War: Korea was ruled by Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Japan and—by agreement with the United States—occupied Korea north of the 38th parallel. U.S. forces subsequently occupied the south and Japan surrendered. By 1948, two separate governments had been set up. Both governments claimed to be the legitimate government of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union and China—invaded South Korea on 25 June 1950. On that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83: Complaint of aggression upon the Republic of Korea and decided the formation and dispatch of the UN Forces in Korea. Twenty-one countries of the United Nations eventually contributed to the defense of South Korea, with the United States providing 88% of the UN's military personnel.
Document 8: Samsung: Samsung was founded by Lee Byung-chul in 1938 as a trading company. Over the next three decades, the group diversified into areas including food processing, textiles, insurance, securities, and retail. Samsung entered the electronics industry in the late 1960s and the construction and shipbuilding industries in the mid-1970s; these areas would drive its subsequent growth. Following Lee's death in 1987, Samsung was separated into four business groups – Samsung Group, Shinsegae Group, CJ Group and Hansol Group. Since 1990, Samsung has increasingly globalised its activities and electronics; in particular, its mobile phones and semiconductors have become its most important source of income. As of 2017, Samsung has the 6th highest global brand value.Notable Samsung industrial affiliates include Samsung Electronics (the world's largest information technology company, consumer electronics maker and chipmaker measured by 2017 revenues), Samsung Heavy Industries (the world's 2nd largest shipbuilder measured by 2010 revenues), and Samsung Engineering and Samsung C&T (respectively the world's 13th and 36th largest construction companies). Other notable subsidiaries include Samsung Life Insurance (the world's 14th largest life insurance company), Samsung Everland (operator of Everland Resort, the oldest theme park in South Korea) and Cheil Worldwide (the world's 15th largest advertising agency measured by 2012 revenues).Samsung has a powerful influence on South Korea's economic development, politics, media and culture and has been a major driving force behind the "Miracle on the Han River". Its affiliate companies produce around a fifth of South Korea's total exports. Samsung's revenue was equal to 17% of South Korea's $1,082 billion GDP.
Document 9: Division of Korea: With the onset of the Cold War, negotiations between the United States and the Soviet Union failed to lead to an independent, unified Korea. In 1948, UN-supervised elections were held in the US - occupied south only. This led to the establishment of the Republic of Korea in South Korea, which was promptly followed by the establishment of the Democratic People's Republic of Korea in North Korea. The United States supported the South, the Soviet Union supported the North, and each government claimed sovereignty over the whole Korean peninsula.
Document 10: Korean War: Korea was ruled by Imperial Japan from 1910 until the closing days of World War II.

Document 12: Samsung Telecommunications: In 1977 Samsung Electronics launched the Telecommunication Network, and in 1983 it initiated its mobile telecommunications business with the hope that this would become the company's future growth engine. In 1986, Samsung was able to release its first built - in car phone, the SC - 100, but it was a failure due to the poor quality. In spite of unsuccessful result Ki Tae Lee, the then - head of the Wireless Development Team, decided to stay in the mobile business. He asked the company to buy ten Motorola mobile phones for benchmarking. After 2 years of R&D Samsung developed its first mobile phone (or ``hand phone ''in Korea), the SH - 100 in 1988. It was the first mobile phone to be designed and manufactured in Korea. But the perception of mobile devices was very low and although Samsung introduced new models every year, each model sold only one or two thousand units.

Document 14: History of Korea: After the end of WWII in 1945, the Allies divided the country into a northern area, protected by the Soviets, and a southern area protected primarily by the United States. In 1948, when the powers failed to agree on the formation of a single government, this partition became the modern states of North and South Korea. The peninsula was divided at the 38th Parallel: the ``Republic of Korea ''was created in the south, with the backing of the US and Western Europe, and the`` Democratic People's Republic of Korea'' in the north, with the backing of the Soviets and the communist People's Republic of China. The new premier of North Korea, Kim il - Sung launched the Korean War in 1950 in an attempt to reunify the country under Communist rule. After immense material and human destruction, the conflict ended with a cease - fire in 1953. The two nations officially remain at war because a peace treaty was never signed. Both states were accepted into the United Nations in 1991.
