Byeonhan confederacy
Byeonhan (Korean: 변한; Hanja: 弁韓; pronounced [pjʌn.ɦan]), also known as Byeonjin (변진; 弁辰; [pjʌn.dʑin]), was a loose confederacy of chiefdoms that existed from around the beginning of the Common Era to the 4th century in the southern Korean peninsula. Byeonhan was one of the Samhan (or "Three Hans"), along with Mahan and Jinhan.
