Balhae (698–926, Korean pronunciation: [pal.ɦɛ], Bohai in Chinese) was a kingdom in present-day northern Korea, areas of China's Northeast, and Russia's Maritime Province. Balhae was established under the name Jin by former Goguryeo general Dae Jo-yeong (King Go) in 698 after his defeat of the Tang China at Tianmenling. Balhae's original capital was at Dongmo Mountain in modern Dunhua, Jilin Province. In 742 it was moved to the Central Capital in Helong, Jilin. It was moved to the Northern Capital in Ning'an, Heilongjiang in 755, to the Eastern Capital in Hunchun, Jilin in 785, and back to the Northern Capital in 794. According to a Chinese source, the kingdom had 100,000 households and a population of about 500,000. Archaeological evidence suggests that the Balhae culture was an amalgamation of Chinese, Korean, and indigenous cultures. In 926, the Khitan Liao dynasty conquered Balhae and established the autonomous kingdom of Dongdan ruled by the Liao crown prince Yelü Bei, which was soon absorbed into the Liao., while the southern parts of its territory, and a series of nobilities led by crown prince Dae Gwang-hyeon were absorbed into Goryeo.

Korean scholars consider Balhae as the part of the North–South States Period of Korean history, while Chinese scholars consider Bohai as the part of Chinese history.
