Document 3: Names of Korea: An early attempt to translate these characters into English gave rise to the expression ``The Land of the Morning Calm ''for Korea, which parallels the expression`` The Land of the Rising Sun'' for Japan.

Document 4: Chinese characters: After Kim Jong Il, the second ruler of North Korea, died in December 2011, Kim Jong Un stepped up and began mandating the use of Hanja as a source of definition for the Korean language. Currently, it is said that North Korea teaches around 3,000 Hanja characters to North Korean students, and in some cases, the characters appear within advertisements and newspapers. However, it is also said that the authorities implore students not to use the characters in public. Due to North Korea's strict isolationism, accurate reports about hanja use in North Korea are hard to obtain.

Document 9: Korea: According to legend, Dangun, a descendant of Heaven, established Gojoseon in 2333 BC. In 108 BC, the Han dynasty defeated Gojoseon and installed four commanderies in the northern Korean peninsula. Three of the commanderies fell or retreated westward within a few decades, but the Lelang commandery remained as a center of cultural and economic exchange with successive Chinese dynasties for four centuries. By 313, Goguryeo annexed all of the Chinese commanderies.
Document 10: Korea: In 1392, the general Yi Seong-gye overthrew the Goryeo dynasty after he staged a coup and defeated General Choe Yeong. Yi Seong-gye named his new dynasty Joseon and moved the capital from Kaesong to Hanseong (formerly Hanyang; modern-day Seoul) and built the Gyeongbokgung palace. In 1394, he adopted Confucianism as the country's official ideology, resulting in much loss of power and wealth by the Buddhists. The prevailing philosophy of the Joseon dynasty was Neo-Confucianism, which was epitomized by the seonbi class, scholars who passed up positions of wealth and power to lead lives of study and integrity.

Document 12: Modern history: In Asia, various Chinese dynasties and Japanese shogunates controlled the Asian sphere. In Japan, the Edo period from 1600 to 1868 is also referred to as the early modern period. And in Korea, from the rising of Joseon Dynasty to the enthronement of King Gojong is referred to as the early modern period. In the Americas, Native Americans had built a large and varied civilization, including the Aztec Empire and alliance, the Inca civilization, the Mayan Empire and cities, and the Chibcha Confederation. In the west, the European kingdoms and movements were in a movement of reformation and expansion. Russia reached the Pacific coast in 1647 and consolidated its control over the Russian Far East in the 19th century.
Document 13: Korean War: Korea was considered to be part of the Empire of Japan as an industrialized colony along with Taiwan, and both were part of the Greater East Asia Co-Prosperity Sphere. In 1937, the colonial Governor-General, General Jirō Minami, commanded the attempted cultural assimilation of Korea's 23.5 million people by banning the use and study of Korean language, literature, and culture, to be replaced with that of mandatory use and study of their Japanese counterparts. Starting in 1939, the populace was required to use Japanese names under the Sōshi-kaimei policy. Conscription of Koreans for labor in war industries began in 1939, with as many as 2 million Koreans conscripted into either the Japanese Army or into the Japanese labor force.
Document 14: North Korea at the Olympics: North Korea (Democratic People's Republic of Korea) first participated at the Olympic Games in 1964, appearing only in the Winter Olympic Games that year.

Since then, the nation has appeared in every Summer Games, except when North Korea joined the Soviet - led boycott of the 1984 Summer Olympics, and when they boycotted the 1988 Games in Seoul, South Korea.
Document 15: Korea: In North Korea, China, Japan, Vietnam, and Chinese and Vietnamese - speaking areas, Korea as a whole is referred to as Chosŏn (조선, Joseon, (tɕoshʌn),, (朝鲜), Cháoxiǎn, (朝鮮), Chōsen, Triều Tiên (朝鮮) lit. ``(land of the) Morning Calm '').`` Great Joseon'' was the name of the kingdom ruled by the Joseon dynasty from 1393 until their declaration of the short - lived Great Korean Empire in 1897. King Taejo had named them for the earlier Kojoseon (고조선), who ruled northern Korea from its legendary prehistory until their conquest in 108 BC by China's Han Empire. This go is the Hanja 古 and simply means ``ancient ''or`` old''; it is a modern usage to distinguish the ancient Joseon from the later dynasty. Joseon itself is the modern Korean pronunciation of the Hanja 朝鮮 but it is unclear whether this was a transcription of a native Korean name (OC * T (r) awser, MC Trjewsjen) or a partial translation into Chinese of the Korean capital Asadal (아사달), whose meaning has been reconstructed as ``Morning Land ''or`` Mountain''.
