Taejo of Joseon Taejo of Joseon (4 November 1335 – 27 June 1408), born Yi Seong-gye (), was the founder and first ruler of the Joseon dynasty of Korea. After ascending to the throne, he changed his name to Yi Dan (), and reigned from 1392 to 1398. He was ...

in 1398, the system of noble titles changed: "duke" for king's sons, "marquis" for royal descendants, and "earl" for officers of senior first rank. This system was abolished in 1401 to avoid "usurping" the existing title laws of the more powerful

approved a new system for giving titles to the royalty: among the sons of a king, those who were born by the queen can acquire the title "grand prince" (대군), and the rest can be the "prince" (군); both princes are of senior first rank and their male descendants are as well insofar as their great-grandsons can retrieve official positions. According to the
Veritable Records of the Joseon Dynasty The ''Veritable Records of the Joseon Dynasty'' (also known as the ''Annals of the Joseon Dynasty'' or the ''True Record of the Joseon Dynasty''; ko, 조선왕조실록 and ) are the annual records of Joseon, the last royal house to rule ...
, the title "prince" (군) was at first restricted to be given to sons or grandsons of kings, but these standards became looser over time. Generally, a royal eligible to be a prince could not receive the title automatically even if his rank raised him to the junior second rank. But such a hereditary title could be passed down to generations until it exceeds more than four generations (from the king). (King Gojong Year 02, Month 11, Day 1, Entry 1) Similar to male royals, female royals received titles according to their kinship to the kings. Despite all being called "princess" in English, daughters of the king and queen were called 공주 (''gongju''). Girls born to other consorts and fathered by the king were called 옹주 (''ongju'') to differentiate; some further distant female royalties also had different titles. If the above-mentioned females were stripped of titles due to various reasons, they would be referred to as a commoner; for instance, the eldest daughter of deposed
