||In this thesis I attempt to prove that Emperor Wu of Southern Qi was ruling his kingdom as a Buddharaja, he who is Buddha is raja/cakravartin. A cakravartin is one who rules his state with Buddhist belief. As a Buddha, Emperor Wu took the disguise of Buddha Maitreya. This Buddhist kingship is documented in the “Gaṇḍa-vyūha” of Avatamsaka. Emperor Wu might have ascended his throne of Buddharaja in the first year of Yongming. He was not the first emperor in the Southern Dynasties implementing this Buddhist kingship to rule his country. Many of his predecessors had ruled their countries with the same kingship. As the kingship was established on the Buddhist cakravartinship founded by King Aśoka in India, Emperor Wu had followed the footsteps of King Aśoka very closely. For instance, in order to show his compassion to all sentient beings, he also forbad killing and fishing in his kingdom.
