Princess Seonhwa of Silla

Princess Seonhwa, which according to the Samguk Yusa, was a Silla Royal Princess as the third daughter of King Jinpyeong and Lady Maya, younger sister to Princess Deokman and Princess Cheonmyeong. She was also the queen consort of Baekje since 600 CE as the wife of King Mu.

However, her existence is controversial due to the discovery of evidence that points to King Uija's mother as being Queen Sataek and not Seonhwa as indicated by historical records. There is also a theory said that Seonhwa married to King Dongseong, not King Mu, which made various hypotheses about her status, such as the princess of Baekje, a noblewoman, even a daughter of a local noble instead of Silla's princess.
