Document 2: 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 3: Korean War: The Korean War (in South Korean Hangul: 한국전쟁; Hanja: 韓國戰爭; RR: Hanguk Jeonjaeng, ``Korean War ''; in North Korean Chosŏn'gŭl: 조국해방전쟁; Hancha: 祖國解放戰爭; MR: Choguk haebang chǒnjaeng,`` Fatherland Liberation War''; 25 June 1950 -- 27 July 1953) was a war between North Korea (with the support of China and the Soviet Union) and South Korea (with the principal support of the United States). The war began on 25 June 1950 when North Korea invaded South Korea following a series of clashes along the border. The United Nations, with the United States as the principal force, came to the aid of South Korea. China came to the aid of North Korea, and the Soviet Union also gave some assistance to the North.
Document 4: 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 5: 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 6: Shin (Korean surname): Shin is a Korean family name. It is cognate to the Chinese family names Shēn and Xin. According to the 2000 census in South Korea, there were 911,556 people carrying the Shin surname.
Document 7: 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 8: Korean War: Korea was ruled by Imperial Japan from 1910 until the closing days of World War II. In August 1945, the Soviet Union declared war on Imperial Japan, as a result of an agreement with the United States, and liberated Korea north of the 38th parallel. U.S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments. Both claimed to be the legitimate government of all of Korea, and neither accepted the border as permanent. The conflict escalated into open warfare when North Korean forces -- supported by the Soviet Union and China -- moved into the south on 25 June 1950. On 27 June, the United Nations Security Council authorized the formation and dispatch of UN forces to Korea to repel what was recognized as a North Korean invasion. Twenty - one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UN's military personnel.

Document 10: Chinese name: Modern Chinese names consist of a surname known as xing (姓, xìng), which comes first and is usually but not always monosyllabic, followed by a personal name called ming (名, míng), which is nearly always mono - or disyllabic.

Document 12: Chinese characters: When learning how to write hanja, students are taught to memorize the native Korean pronunciation for the hanja's meaning and the Sino-Korean pronunciations (the pronunciation based on the Chinese pronunciation of the characters) for each hanja respectively so that students know what the syllable and meaning is for a particular hanja. For example, the name for the hanja 水 is 물 수 (mul-su) in which 물 (mul) is the native Korean pronunciation for "water", while 수 (su) is the Sino-Korean pronunciation of the character. The naming of hanja is similar to if "water" were named "water-aqua", "horse-equus", or "gold-aurum" based on a hybridization of both the English and the Latin names. Other examples include 사람 인 (saram-in) for 人 "person/people", 큰 대 (keun-dae) for 大 "big/large//great", 작을 소 (jakeul-so) for 小 "small/little", 아래 하 (arae-ha) for 下 "underneath/below/low", 아비 부 (abi-bu) for 父 "father", and 나라이름 한 (naraimreum-han) for 韓 "Han/Korea".
Document 13: 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 15: 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.
