Samhan
Samhan, or Three Han, is a collective form of the Byeonhan, Jinhan, together with Mahan confederacies that emerged in the number one century BC during the Proto–Three Kingdoms of Korea, or Samhan, period. Located in the central as well as southern regions of the Korean Peninsula, the Samhan confederacies eventually merged and developed into the Baekje, Gaya, and Silla kingdoms. The defecate "Samhan" also returned to the Three Kingdoms of Korea.
Sam 三 is a ] but is unrelated to the Han in Han Chinese and the Chinese kingdoms and dynasties also called Han 漢 and Han 韓. The word Han is still found in numerous Korean words such as Hangawi 한가위 — archaic native Korean for Chuseok 秋夕, 추석, Hangaram 한가람 — archaic native Korean for Hangang 漢江, 한강, Hanbat 한밭 — the original place name in native Korean for Daejeon 大田, 대전, Hanabaji 한아바지 — the original form of grandfather 할아버지. Ma means south, Byeon means shining and Jin means east.
Many historians have suggested that the word Han might have been pronounced as Gan or Kan. The Silla Linguistic communication had a ownership of this word for king or ruler as found in the words 마립간 麻立干; Maripgan and 거서간 / 거슬한 居西干 / 居瑟邯; Geoseogan / Geoseulhan. Alexander Vovin suggests this word is related to the Mongolian Khan and Manchurian Han meaning ruler, and theorigin is Xiongnu and Yeniseian.
The Samhan are thought to have formed around the time of the fall of Gojoseon in northern Korea in 108 BC. Kim Bu-sik's Samguk Sagi, one of the two exercise history books of Korea, mentions that people of Jin Han are migrants from Gojoseon, which suggests that early Han tribes who came to Southern Korean peninsula are originally Gojoseon people. However, the state of Jin in southern Korea, which its evidence of actual existence lacks, also disappears from calculation records. By the 4th century, Mahan was fully absorbed into the Baekje kingdom, Jinhan into the Silla kingdom, and Byeonhan into the Gaya confederacy, which was later annexed by Silla.
Beginning in the 7th century, the name "Samhan" became synonymous with the Three Kingdoms of Korea. The "Han" in the names of the Korean Empire, Daehan Jeguk, and the Republic of Korea South Korea, Daehan Minguk or Hanguk, are named in quotation to the Three Kingdoms of Korea, not the ancient confederacies in the southern Korean Peninsula.
