Chimnyu of Baekje
Chimnyu of Baekje (died 385) (r. 384–385) was the fifteenth king of Baekje, one of the Three Kingdoms of Korea. Background. He was the eldest son of the 14th king, Geungusu and Lady Ai of the Jin clan. He became king upon Geungusu's death in 384 which was the 10th year of his reign. Reign. Samguk Sagi: Legacy. He was the first Baekje king to officially recognize Buddhism. According to the "Samguk sagi" and "Samguk yusa", the two oldest extant histories of Korea, Buddhism was officially introduced to Korea during the 4th century during the Three  Kingdoms period. In 384, the Indian Buddhist monk Marananta came to Baekje from Eastern Jin. King Chimnyu welcomed him into the palace, and shortly thereafter adopted Buddhism. Archaeological discoveries have corroborated these assertions of the early introduction of Buddhism into Korea with the discovery of Goguryeo tomb murals with Buddhist motifs and the excavation of lotus shaped roof tiles dated to the 4th century. In 385, the king ordered that a Buddhist temple be built at the Baekje capital of Hansan (suggested, but not certain, to be at Bukhansanseong), and ten people became monks. After his death his brother Jinsa  was crowned but after his death Chimnyu's eldest son became the next king, Asin of Baekje. After Asin's death in 405 his three other sons fought for the crown ending in all of their deaths and the crowning of Asin's son.
