During the first Japanese invasion of Korea, Japanese forces led by Toyotomi Hideyoshi captured Pyongyang, although they were ultimately unable to hold it.

The Imjin War was a series of two Japanese invasions of Korea: an initial invasion in 1592 also individually called the "Imjin War", a brief truce in 1596, and a second invasion in 1597 called the Chŏngyu War. The conflict ended in 1598 with the withdrawal of Japanese forces from the Korean Peninsula after a military stalemate in Korea's southern provinces.

Toyotomi Hideyoshi , otherwise known as Kinoshita Tōkichirō and Hashiba Hideyoshi , was a Japanese samurai and daimyō of the late Sengoku and Azuchi-Momoyama periods and regarded as the second "Great Unifier" of Japan. Although he came from a peasant background, his immense power earned him the rank and title of Kampaku and Daijō-daijin , the highest official position and title in the nobility class. He was the first person in history to become a Kampaku who was not born a noble. He then passed the position and title of Kampaku to his nephew, Toyotomi Hidetsugu. He remained in power as Taikō (太閤), the title of retired Kampaku, until his death. It is believed, but not certain, that the reason he refused or could not obtain the title of shogun (征夷大将軍), the leader of the warrior class, was because he was of peasant origin.

Pyongyang is the capital and largest city of North Korea, where it is sometimes labeled as the "Capital of the Revolution". Pyongyang is located on the Taedong River about 109 km (68 mi) upstream from its mouth on the Yellow Sea. According to the 2008 population census, it has a population of 3,255,288. Pyongyang is a directly administered city with a status equal to that of the North Korean provinces.
