SamhanSamhan, or Three Han, is the collective name of the Byeonhan, Jinhan, and Mahan confederacies that emerged in the first century BC during the Proto–Three Kingdoms of Korea, or Samhan, period. Located in the central and southern regions of the Korean Peninsula, the Samhan confederacies eventually merged and developed into the Baekje, Gaya, and Silla kingdoms. The name "Samhan" also refers to the Three Kingdoms of Korea. Sam (三) is a Sino-Korean word meaning "three" and Han is a Korean word meaning "great (one), grand, large, much, many".
Jeju languageJeju (Jeju: 제줏말; Jeju RR: , or , or ), often called Jejueo or Jejuan in English-language scholarship, is a Koreanic language originally from Jeju Island, South Korea. It is not mutually intelligible with mainland Korean dialects. While it was historically considered a divergent Jeju dialect of the Korean language, it is increasingly referred to as a language. It is declining in usage, and was classified by UNESCO in 2010 as critically endangered, the highest level of language endangerment possible.
HangulThe Korean alphabet, known as Hangul (ˈhɑːnguːl ; ) in South Korea and Chosŏn'gŭl () in North Korea, is the modern official writing system for the Korean language. The letters for the five basic consonants reflect the shape of the speech organs used to pronounce them, and they are systematically modified to indicate phonetic features; similarly, the vowel letters are systematically modified for related sounds, making Hangul a featural writing system.
Japonic languagesJaponic or Japanese–Ryukyuan, sometimes also Japanic, is a language family comprising Japanese, spoken in the main islands of Japan, and the Ryukyuan languages, spoken in the Ryukyu Islands. The family is universally accepted by linguists, and significant progress has been made in reconstructing the proto-language. The reconstruction implies a split between all dialects of Japanese and all Ryukyuan varieties, probably before the 7th century. The Hachijō language, spoken on the Izu Islands, is also included, but its position within the family is unclear.
Genetic relationship (linguistics)Two languages have a genetic relationship, and belong to the same language family, if both are descended from a common ancestor through the process of language change, or one is descended from the other. The term and the process of language evolution are independent of, and not reliant on, the terminology, understanding, and theories related to genetics in the biological sense, so, to avoid confusion, some linguists prefer the term genealogical relationship.
Book of the Later HanThe Book of the Later Han, also known as the History of the Later Han and by its Chinese name Hou Hanshu (), is one of the Twenty-Four Histories and covers the history of the Han dynasty from 6 to 189 CE, a period known as the Later or Eastern Han. The book was compiled by Fan Ye and others in the 5th century during the Liu Song dynasty, using a number of earlier histories and documents as sources. In 23 CE, Han dynasty official Wang Mang was overthrown by a peasants' revolt known as the Red Eyebrows.
Deportation of Koreans in the Soviet UnionThe deportation of Koreans in the Soviet Union (Депортация корейцев в СССР; 고려인의 강제 이주) was the forced transfer of nearly 172,000 Soviet Koreans (Koryo-saram) from the Russian Far East to unpopulated areas of the Kazakh SSR and the Uzbek SSR in 1937 by the NKVD on the orders of Soviet leader Joseph Stalin and Chairman of the Council of People's Commissars of the Soviet Union Vyacheslav Molotov. 124 trains were used to resettle them 6,400 km (4,000 miles) to Central Asia.
KoreansKoreans are an East Asian ethnic group native to Korea. The majority of Koreans live in the two states of North and South Korea, which are collectively referred to as Korea. As of 2021, an estimated 7.3 million ethnic Koreans resided outside of Korea. Koreans are also an officially recognized ethnic minority in other Asian countries, including China, Japan, Kazakhstan, Russia, and Uzbekistan. Outside of Asia, sizeable Korean communities have formed in Germany, the United Kingdom, France, the United States, Canada, and Oceania.
Gaya confederacyGaya (, ka.ja) was a Korean confederacy of territorial polities in the Nakdong River basin of southern Korea, growing out of the Byeonhan confederacy of the Samhan period. The traditional period used by historians for Gaya chronology is AD 42–532. According to archaeological evidence in the third and fourth centuries some of the city-states of Byeonhan evolved into the Gaya confederacy, which was later annexed by Silla, one of the Three Kingdoms of Korea. The individual polities that made up the Gaya confederacy have been characterized as small city-states.
Jinhan confederacyJinhan (tɕin.ɦan) was a loose confederacy of chiefdoms that existed from around the 1st century BC to the 4th century AD in the southern Korean Peninsula, to the east of the Nakdong River valley, Gyeongsang Province. Jinhan was one of the Samhan (or "Three Hans"), along with Byeonhan and Mahan. Apparently descending from the Jin state of southern Korea, Jinhan was absorbed by the later Silla, one of the Three Kingdoms of Korea. Jinhan, like the other Samhan confederacies, arose out of the confusion and migration following the fall of Wiman Joseon in 108 BC.
