Little Goguryeo

Lesser Goguryeo or Little Goguryeo (699-820) (소고구려, 小高句麗) was a state established by the refugees of Goguryeo, one of the Three Kingdoms of Korea.

The kingdom was originally called Goryeo, but later historians added "Lesser" for disambiguation from Goguryeo, which was also often called Goryeo. "Goryeo" is also the name of a later period of Korean history (see Goryeo), and the source of the English name Korea.

After the Korean Silla kingdom and the Chinese Tang Dynasty allied to destroy Goguryeo, the Liaodong Peninsula was briefly administered by Tang. Tang soon lost effective control due to rebellion by Goguryeo refugees, and the region became a buffer zone between Tang and the Korean kingdom of Balhae. Although Lesser Goguryeo declared itself an independent kingdom, it was soon absorbed into Balhae, which became the successor state to Goguryeo.
