Geungusu of Baekje

Geungusu was the eldest son of the 13th king Geunchogo, and father to the 15th king Chimnyu and the 16th king Jinsa. In 369, as crown prince, Geungusu led the Baekje armies against invading troops of the northern Korean kingdom Goguryeo, capturing 5,000 prisoners. He pushed on to Pyongyang and Sugok-seong in 371, killing Goguryeo's king Gogugwon in battle.

He continued his father's policies, and his father's alliance with the Jin clan. His chief minister, Jin Godo (眞高道), was the father of his queen, Lady Ai (阿尒夫人).

During Geungusu's reign, Baekje was in hostile relations with its northern neighbor, Goguryeo, because of Baekje's attacks on Pyongyang, and the murder of a Goguryeo king during one of the battles. He continued these hostilities as king, taking Pyongyang in 377 with 30,000 men. Had he pushed onto Goguryeo, which was still under turmoil with Gogugwon's death, then Baekje would have completed the conquest of Goguryeo.

Baekje continued as the military and economic power it was during his father's reign. Geungusu maintained friendly relations with China and Yamato period Japan. He is recorded in the Nihonshoki as having sent the noted Baekje scholar Wang In to Japan with copies of the Analects of Confucius and one copy of the Thousand Character Classic. However, on the basis of Korean accounts some believe that this took place decades later, in the reign of King Asin.

There were several astonishing weather-related events during his reign, such as the raining dirt incident in 379. A severe drought in 382 also showed the king's love for his people, as he opened up the kingdom's food storages and fed the people.

Samguk Sagi: "King Geungusu was also called Hwisu. Geungusu was the son of King Geunchogo. Previously, Sayu, king of Goguryeo, himself came and invaded. King Geunchogo dispatched the crown prince to repel them, and he reached Bangeolyang and was goiung to give battle. A man from Goguryeo called Sagi, who was originally a man from Baekje and had mistakenly injured the hoof of the king's steed, feared punishment and fled to Goguryeo. Returning to Baekje at this time, he told the crown prince, "Their soldiers are many, but all of their numbers are meant to deceive you. The only valiant troops are the ones with the red banners — if you first break them, the other troops will not attack and flee of their own accord." The crown prince followed his advice, and attacked and put them to a great rout, and he pursued them to the north, reaching all the way to the northwest of the fortress of Sugok. Geneal Makgohae then admonished him, saying "I have heard the taoists say, "Know when you have enough, and you will not be humiliated. Know when to stop, and you will not put yourself in danger. Now we have gained much: why do we need to seek more?" The prince thought it good and stopped, and raised a mound of rocks as a memorium. Then he climbed to the top of it and said to those around him, "After today, who will again come to this place?" The earth there is full of cliffs and rocks, and cracked like the hoof of a horse. Other people, up to the present, stil call this place "the hoofprints of the crown prince." Geunchogo died in the 30th year of his reign, and Geungusu succeeded him."
