Jilin (Chinese: 吉林; pinyin: Jílín; former official name: Kirin) is one of the three provinces of Northeast China. Jilin borders North Korea and Russia to the east, Heilongjiang to the north, Liaoning to the south, and Inner Mongolia to the west.
In ancient times, Jilin was inhabited by various peoples, notably the Xianbei, Koreans, the Mohe and the Wùjí (勿吉). Various Korean kingdoms, including the Buyeo, Goguryeo and Balhae, were established in this area.
The region then fell successively under the domination of the Xiongnu, Xianbei state, Khitan Liao Dynasty, the Jurchen Jin Dynasty, and the Mongol Yuan Dynasty. During the Qing Dynasty, much of the area was under the control of the General of Jilin, whose area of control extended to the Sea of Japan to encompass much of what is Russia's Primorsky Krai today. Immigration of Han Chinese was strictly controlled.
