Holbon (Korean: 홀본; Hanja: 忽本) was the first capital of Goguryeo, which arose in the north of the Korean Peninsula. Holbon is thought to have been in modern Wunü Mountain, Liaoning. In 37 BC, Jumong had fled from Dongbuyeo to avoid death at the hands of Dongbuyeo's Crown Prince Daeso, who presented great jealousy towards Jumong. After he fled, Jumong established a new kingdom in 37 BC called Goguryeo in the Holbon region. In Holbon, he married Soseono (or So Seo-no), who was the daughter of a local tribal leader.
