Singu
Overview
Singu (新舊) was a small state (小國) or tribal league that existed in the southern region of the ancient Korean Peninsula, a political group corresponding to the Proto–Three Kingdoms period (原三國時代) before the Three Kingdoms era. It is presumed to have been located mainly in the present-day Gyeongsangnam-do area and is mentioned as one of the twelve small states of Byeonhan (弁韓) recorded in the "Records of the Three Kingdoms" (三國志), Book of Wei, Chapter on the Eastern Barbarians (魏書 東夷傳). Singu grew as a member of the Byeonhan confederation based on iron culture and agriculture, and is evaluated as having contributed to the formation of the Gaya confederation (加耶聯盟).

Historical Background
Singu is estimated to have existed from around the 1st century BCE to the 3rd century CE. This period was when iron culture was being fully introduced to the Korean Peninsula and various tribal states were forming confederations. Byeonhan, along with Mahan (馬韓) and Jinhan (辰韓), constituted the Samhan (三韓), and Singu was recorded as one of Byeonhan's twelve small states. According to the "Records of the Three Kingdoms," Byeonhan consisted of a total of twelve states, and Singu was one of them, likely located in the Gimhae, Changwon, and Haman areas of Gyeongsangnam-do, which were the centers of Byeonhan at the time.
Location and Scale
The exact location of Singu has not been clearly identified to date, but scholars consider the Uichang-gu or Masanhappo-gu areas of Changwon City, Gyeongsangnam-do, as strong candidates. Some records suggest that Singu was located in a region adjacent to the sea, advantageous for fishing and maritime trade. Its scale is believed to have been similar to other Byeonhan small states, comprising several hundred to several thousand households, with iron production and agriculture as its main economic foundations.
Politics and Society
Singu was a small state with its own ruler but maintained loose ties with other small states within the Byeonhan confederation. Its political system was a chiefdom society ruled by a military leader (君長), and social stratification progressed with the spread of iron weapons and farming tools. Iron production, in particular, was the economic foundation of Singu, which prospered through trade with neighboring regions. The social structure consisted of a ruling class, ordinary farmers, and slaves, with the ruling class accumulating wealth through iron and trade.
Culture and Religion
The culture of Singu shared common characteristics of the Byeonhan region. Artifacts from the Bronze Age, along with iron artifacts, have been excavated, with dolmens (지석묘) and stone mound tombs (적석묘) appearing as major burial styles. Religiously, shamanism (무속 신앙) was prevalent, and rituals venerating the Heavenly God (天神) and Mountain God (山神) were performed. Additionally, technological developments related to iron production reflect the cultural level of Singu at the time.
Decline and Influence
Singu gradually became integrated during the formation of the Gaya confederation after the 3rd century. Particularly with the rise of Geumgwan Gaya (金官伽耶), Singu lost its identity as an independent political entity and was incorporated into the Gaya confederation. Later, in the 5th–6th centuries, it was completely absorbed due to the expansion of Silla. The legacy of Singu influenced the formation of Gaya and Silla cultures, with its iron technology and maritime trade traditions continuing into later periods.
Recent Trends
As of 2024–2025, archaeological research on Singu is actively ongoing. Some remains excavated in the Changwon area of Gyeongsangnam-do are presumed to be related to Singu, with particular attention on iron smelting furnaces and settlement sites. In 2024, a large-scale iron production site estimated to date from the Singu period was discovered in the Uichang-gu area of Changwon City, drawing academic interest. Additionally, research using digital restoration technology to reconstruct the geographical scope and social structure of Singu is underway, and new research findings are scheduled to be presented at an academic conference in 2025. These studies are contributing to revealing the reality of Byeonhan small states, including Singu.
