This was made possible by the new wealth and prestige garnered as a result of Silla's unification of the peninsula, as well as the monarchy's successful suppression of several armed aristocratic revolts following early upon unification, which afforded the king the opportunity of purging the most powerful families and rivals to central authority.
Dette blev muliggjort af den nye rigdom og prestige vundet som følge af Sillas forening af halvøen, samt monarkiets vellykkede undertrykkelse af flere bevæbnede aristokratiske oprør, som indtraf kort efter foreningen, hvilket gav kongen mulighed for at udrense de mest magtfulde familier og rivaler fra den centrale myndighed.
