The results of this theis are as follows. As regards the chronological transformation of the royal court dancing which is characterized by the variousness and colorfulness of the old-fashioned dancing suit, in the pre-dynasty of triple alliance among Shinla, Bakjae, and Goguryeo, the traditional ritual stood on ceremony through the ceremonial dancing in support of a religional rite. But while the Shinla, Bakjae, and GoGuRyeo dynasty began to excercise the systematic royal control over people, each royal court employed the professional ritual dancers; and it encouraged them to dance on the variety of ceremony on behalf of a rite and celebration. Of course, except for that of Shinla dynasty, it is not so easy to find out the historical record for the evidence which can back up these facts. As representatives of a ritual dancing, the religional ceremony of Shinla dynasty brought about the orientation of GumGee-Mu, MooAe-Mu, Saseon-Mu, Seonyu-Ak, and Cheoyong-Mu.
