The bone rank system was the system of aristocratic rank used in the ancient Korean kingdom of Silla. It was used to segregate society, and particularly the layers of the aristocracy, on the basis of their hereditary proximity to the throne and the level of authority they were permitted to wield. The idea of royal blood in other societies is a close analogue to the idea of "sacred bone" in Silla thought.

Bone rank was strictly hereditary, and thus acted as a caste system. The scholar, Lee Ki-Baik (1984, p. 43) considers it to have probably been adopted as part of the administrative law introduced from China and promulgated by King Beopheung in 520. However, this likely did nothing but institute in legal fact what was already a society segregated by bloodline and lineage. Although only two of the five known ranks were referred to as "bone" (골, 骨), the term "bone rank" has become widely used to describe the whole system.

The hierarchy and features

Relationship of Bone-Rank Gradations in Silla to Office Rank and Post ^[1]

A person's bone rank status governed not only official status and marriage rights, but also the color of one's garments and the maximum dimensions of one's dwelling and carriage. These criteria are described in detail in the 12th century Korean history Samguk Sagi, particularly its Monographs (ji 志), book 2 (ranks and offices). The Samguk Sagi's depiction of Silla life, however, has often been criticized for being excessively static. Unfortunately, since other sources are scarce, it is difficult to judge what sort of changes may have taken place in the bone rank system over the centuries.

The highest level of the bone rank was the "sacred bone", or seonggol (성골, 聖骨), sometimes termed "hallowed bone", which consisted only of a portion of the royal Kim family, possibly those considered to have royal blood on both sides. Until this rank was abolished with the ascension of King Muyeol in 654, only those holding sacred bone rank were permitted to assume the throne. This led to the crowning of Queen Seondeok in 632 and Queen Jindeok in 647, because no males of the sacred bone rank were available. This situation may have led to its subsequent abolition.

Below the sacred bone came the "true bone", or jingol (진골, 眞骨), which included the rest of the royal family, as well as the Bak and Seok families of Gyeongju, which had held the throne in very early times and were involved in most royal marriages, as well as another Kim ['Kimhae' royal clan] lineage descended from the royal house of Geumgwan Gaya. Members of the true bone could hold any official position, up to the level of full minister. They could also attain office rank up to the highest, ibolchan (이벌찬). After the sacred bone rank was abolished under King Muyol, only those holding the true bone rank could become king.

Below the "true bone" came the head ranks (두품, 頭品), of which only the 6th, 5th and 4th are attested, 6th being the highest. The origins of these lower head rank classes and what defined one‘s status as such are obscure and still debated among scholars. As the jingol were prohibited from marrying into the lower ranks, though they could take concubines from them, it is feasible that one source of the head rank six were the children born from unions between jingol fathers and lower ranking concubines. In any case, members of the head rank six could rise to the position of vice-minister (gyeong, 경, 卿) and as high as the 6th level of office rank, achan (아찬, 阿餐) (two higher ranks of jungachan (중아찬, 重阿餐) and sajung achan (사중아찬, 四重阿餐) were later supplemented to that of achan but these still fell within the 6th level). Members of head ranks four and five could rise only to minor posts. Members of head rank five could reach the 10th level of office rank, daenaema (대내마, 大奈麻), while members of head rank four could attain only the 12th level of office rank, daesa (대사, 大舍). There were 17 levels of office rank altogether. One scholar has proposed that, "head-ranks three, two, and one, if they ever formally existed, must have designated the ... non-privileged general populace."^[2]

Evaluations

The frustrated ambitions of the head rank six class in particular seem to have played a prominent role in the politics of the late Silla period. Many men of head rank six status, proscribed from rising too high in the Silla administrative system defined by the bone rank system, sought to bypass this by studying Confucianism (either in Silla or abroad in Tang China) or else turned to careers in Buddhism. The most prominent of the head rank six figures was undoubtedly Choe Chiwon, who following an illustrious career in China returned to Silla only to see his attempts at administrative reform rebuffed by an entrenched aristocracy. In the early 10th century the nascent state of Goryeo, which succeeded Silla, tapped into the head rank six intellectuals to man its bureaucracy.

The bone rank system's extreme rigidity certainly helped to weaken Silla toward the end of the Unified Silla period, although numerous other factors were at play. After the fall of Silla, the bone rank system was abolished entirely, although different and somewhat more flexible caste systems persisted until near the end of the Joseon Dynasty in the late 19th century.
