In 111, the king of Buyeo reportedly sent 7.000 to 8.000 horsemen to raid the Lelang Commandery of the later Han. In 120, in reconciliation, he sent his heir, Wigutae, to pay tribute to emperor An, who gave him a golden medal and a seal.[1]
In 121, king Taejodae of Goguryeo led thousands of horsemen from the area of the Mahan confederacy to the area of the Yemaek people to attack the Xuantu commandery. The king of Buyeo then sent his heir, Wigutae, with 20.000 men to repel the forces of Goguryeo.[1]
When Wutae came to the throne, he married a daughter of Gongsun Du, an influential warlord from the Liaodong peninsula.[2]
After his death he would be succeeded by his son, Gangwigeo.[2]
