, was the 29th ruler of Silla, one of the Three Kingdoms of Korea. He is credited for leading the unification of Korea's Three Kingdom.
Background
King Taejong Muyeol was born with the "sacred bone" rank of seonggol. His father, Kim Yongsu (金龍樹), was a son of Silla's 25th ruler, King Jinji. When King Jinji was overthrown, all royalty from his line, including Kim Yongsu, were deemed unfit to rule over the kingdom. However, as Yongsu was one of the few remaining seonggols, and married a seonggol princess (King Jinpyeong's daughter Princess Cheonmyeong), their child, Kim Chunchu, became seonggol and thus had a claim to the throne. Kim Yongsu was a powerful figure in the government; however, he lost all of his power to Kim Baekban, the brother of the king. In order to survive, he accepted to become a jingol, the rank that was right below seonggol, therefore removing the right of becoming the king for him and his son, Kim Chunchu. Following the death of his aunt, Queen Seondeok, Chunchu was passed over in favor of Jindeok of Silla, the last verifiable seonggol. With her death, all the seonggols were dead, so somebody with the royal blood in the jinggol rank had to succeed the throne. Kim Alcheon (So Alcheon), who then held the title Sangdaedeung, or highest post of government, of Silla was the original favorite to succeed the throne. His father was a seonggol, who married a jingol woman so that his son would not be a seonggol and suffer from the fight for the throne. However, Kim Yushin supported Kim Chunchu, and Alcheon eventually refused the throne and supported Chunchu's claim. As a result, Kim Chunchu succeeded the throne as King Muyeol.
Marriage to Kim Yushins sister
Kim Yushin had two sisters: Bohee and Munhee. Bohee was a shy girl with a delicate appearance, while Munhee was a tall and outgoing girl. Kim Yushin had always hope for one of his sisters to be married to Kim Chunchu.
One day, Kim Chunchu went to Kim Yushin's house for a game of Gyeokgu (격구, traditional Korean polo). During the game, Kim Yushin deliberately tore off one of the tassels on Kim Chunchu's robe. Kim Yushin offered to have it sewn by one of his sisters; he then sent for Bohee to have it mend, but she was too nervous to come into the presence of a stranger, and politely refused by saying that "she cannot do something so small for someone so precious". Munhee stepped out and offered to sew it instead. When they met, Kim Chunchu and Munhee fell in love with each other. Kim Chunchu started to visit Munhee more often, but Kim Yushin pretended not to be aware of their relationship. Eventually, Munhee became pregnant, however, Kim Chunchu decided to keep it a secret in fear of causing trouble since he was already a married man. When Kim Yushin found out about it, he scolded his sister severely, then ordered their servants to spread the rumor of his sister's pregnancy and that he might kill her because of it in a plan to pressure Kim Chunchu into marrying his sister.
Not long afterwards, Queen Seondeok decided to take a walk with her officials on the Namsan Mountain. When he heard of it, Kim Yushin made a pile of dry logs and twigs in the garden outside of his house and set it on fire for the Queen to see. High up on the mountain, the Queen noticed the black smoke that was coming from Yushin's residence area, and asked those accompanying her if they knew the reason. No one dared to answer her, but simply looked at one another in embarrassment. When the Queen pressed on the issue, she finally learned from them about the rumor of Munhee's pregnancy out of wedlock and that Kim Yushin might burn her to death because of it. She was astonished with what they said and wondered "Who could the father be, to make Kim Yushin act like that". She then noticed the anxious look on Kim Chunchu's face and asked if he knew anything about it. After the truth was revealed, the Queen ordered him to go and save Munhee's life by granting him the permission to marry her as his second wife, to become his lawful spouse when his first wife died.
Munhee officially became his wife after Kim Chunchu's wife (Boryang) died of childbirth with their second child. She became his Queen after he was crowned as the 29th King of Silla on year 654. Their child grew up to be King Munmu, who completed the unification of The Three Kingdoms of Korea, 29 years after Queen Seondeok's death. Kim Yushin became the most powerful man in the court during King Muyeol's reign and eventually became a Sangdaedeung, six years later. His sister Bohee also became one of King Muyeol's wives.
Reign
He was well acquainted with the Emperor Gaozong of the Tang Dynasty, for he and the Emperor were friends before Gaozong became an Emperor. King Muyeol was a great support to the Emperor, and the Emperor returned the support to King Muyeol. He constantly pleaded with the Tang for reinforcements to destroy Baekje, to which the Tang finally acquiesced in 660, sending 130,000 troops under General Su Dingfang. Meanwhile, Kim Yushin set out from Silla with 50,000 soldiers and fought the bloody Battle of Hwangsanbeol leaving Baekje devastated and unprotected. King Uija of Baekje finally surrendered, leaving only Goguryeo to face Silla as an adversary on the Korean peninsula.
In June of the following year King Muyeol died, leaving his son Kim Beopmin to assume the throne as King Munmu.
