[3] The history of the state can be divided in two periods: Phanya Coeng, Paya Jueang (Thai: พญาเจื่อง) or Chao Jueang Han (Thai: เจ้าเจื่องหาญ) was said to wage wars with the native Akha and other Tai peoples in the area and established the kingdom in favor of Tai Lü people at Chiang Hung or Heo Kam on the Mekong in 1180.

The tributaries of Heokam kingdom includes Kengtung (Meuang Khün), Chiang Saen (Ngoenyang), Meuang Thaeng (modern Dien Bien Phu – the capital of Tai Dam people), and Xieng Thong (Luang Prabang), making Heokam the sole leader of Tai kingdoms in the north.

[5] The Mongols granted the title Chao Saenwi Fa (Thai: เจ้าแสนหวีฟ้า) and the surname of Dao to the Kings of Chiang Hung.

The power vacuum in the area was filled by newly formed Lanna kingdom evolving from Ngoenyang state.

According to Siamese chronicles King Mahawan of Chiang Hung died in 1847, to be succeeded by his son Prince Sarawan.

The Burmese invaded and took Chiang Hung - culminating a large Tai Lue emigration into Lanna.

The last chieftain of Jinghong, Dao Shixun, attended the foundation ceremony of the People's Republic of China in 1949, and later became president of the Yunnan Minzu Institute.

Following constant warfare in the late 18th century, a large number of Tai Lue people were displaced.

Some members of the ruling family, such as Dao Shixun's brother, fled to Mae Sai district in Chiang Rai, Thailand in 1949.
