## Biography

Princess Cheonmyeong was a daughter of King Jinpyeong and Queen Maya of Silla. Her sister, Queen Seondeok became the first female ruler of Korea. It is not clear which of them was older. According to the disputed text Hwarang Segi, Cheonmyeong was older than Seondeok.
It is said that Princess Cheonmyeong was in love with Kim Yongchu. When the talk of her marriage has come, Princess Cheonmyeong went to the Queen and told her (with tears on her eyes) that she cannot marry anyone else because there is already a man who owns her heart. Queen Maya asked her who that man is, Princess Cheonmyeong tried to say "Kim Yongchun" but because she was crying and stuttered on her reply, the Queen thought that she was talking about Kim Yongchu's brother "Kim Yongsu". Kim Yongsu was aware of Princess Cheonmyeong's feelings for his brother and decided to ask him to marry Princess Cheonmyeong on his stead. But Kim Yongchun refused out of respect for his brother who might end up a laughing stock since their wedding was already announced. The Queen tried to convinced him as well but he refused her as well with the same reason. And so, Princess Cheonmyeong and Kim Yongsu got married. But Princess Cheonmyeong wasn't able to forget her love even after years has passed. On his death bed, Kim Yongsu asked his brother once again to marry Princess Cheonmyeong and to take his son as his own as his dying wish. Kim Yongchun finally agreed and married Princess Cheonmyeong and took Kim Chunchu as his own. But this story is not mentioned in the historical texts Samguk sagi and Samguk yusa. This story is only mentioned in the disputed text Hwarang Segi.
After Kim Chunchu was crowned as the 29th king of Silla, Princess Cheonmyeong was named as Queen Dowager Munjeong.
