Injong of Goryeo, personal name Wang Hae, was the 17th monarch of the Korean Goryeo dynasty. He was the eldest son of King Yejong and Queen Sundeok, the daughter of Yi Cha-gyŏm. His reign saw two major internal crises that nearly ended the Goryeo dynasty, the collapse of the Northern Song dynasty, and the establishment of the Jin dynasty as the dominant power in East Asia.

Goryeo was a Korean state founded in 918, during a time of national division called the Later Three Kingdoms period, that unified and ruled the Korean Peninsula until 1392. Goryeo achieved what has been called a "true national unification" by Korean historians as it not only unified the Later Three Kingdoms but also incorporated much of the ruling class of the northern kingdom of Balhae, who had origins in Goguryeo of the earlier Three Kingdoms of Korea. The name "Korea" is derived from the name of Goryeo, also romanized as Koryŏ, which was first used in the early 5th century by Goguryeo. According to Korean historians, it was during the Goryeo period that the individual identities of Goguryeo, Baekje and Silla were successfully merged into a single entity that became the basis of the modern-day Korean identity. Goryeo was the successor state to Later Goguryeo and Goguryeo.
