Longnan was settled by humans at least 7000 years ago. Between 5000 and 6000 years ago, civilizations developed along the Xihan ("Western Han") and Bailong ("White Dragon") rivers. Anping in Wudu as well as Lixian both have ancient ruins. Longnan is very important in Chinese history: it was the home of Rong tribes that troubled the Shang and Zhou dynasties and is considered the homeland of the House of Ying, the family of the Qin dynasty that united China at the end of the Warring States period. Wudu County was even founded as part of the Qin Empire. It is still common to find Qin artifacts—including pottery, bronzes, and coins—in the area.
During the Sixteen Kingdoms period, the region was ruled by the Qiang kingdoms of Later Qin and Tanchang, the latter has its capital in present-day Tanchang. Tanchang is conquered by Emperor Wu of Northern Zhou in 564. The region then went under control of Sui, Tang and Song dynasties, then subsequently conquered by the Tibetans, Tanguts, Jurchens and Mongols before finally administered by Ming dynasty court. Under imperial Chinese rule, the area was administered as Jie Prefecture (t 階州, s 阶州, Jiēzhōu).
Longnan has 1 urban districts, 8 counties, 242 towns, and 3243 villages with a total population of 2567718.[7]
