Tianshui's history stretches back to the dawn of Chinese civilization. The Dadiwan Site, discovered in 1978, reveals continuous human habitation from 8,000 to 5,000 years ago, with evidence of primitive agriculture, animal husbandry, and the earliest known Chinese pottery with symbolic markings.
According to Chinese mythology, Fuxi, the first of the Three Sovereigns, was born in Tianshui. He is credited with inventing the Eight Trigrams (Bagua), teaching people to fish and hunt, and establishing the foundations of Chinese society. Shennong (Yandi), the Divine Farmer, also has strong connections to the region.
During the Qin Dynasty, Tianshui was the seat of Longxi Commandery. The area was the ancestral homeland of the Li family, from which the Tang Dynasty's imperial family descended. Li Bai, one of China's greatest poets, claimed Tianshui as his ancestral home.
In the 4th century AD, the Maijishan Grottoes were begun, marking the arrival of Buddhism in the region. The grottoes were continuously expanded through the Sui, Tang, Song, Yuan, Ming, and Qing dynasties, resulting in a remarkable collection of Buddhist art spanning 1,600 years.
During the Ming and Qing dynasties, Tianshui became a thriving commercial center, with the Silk Road's southern routes passing through the city. The Fuxi Temple was rebuilt in 1490 and remains a major pilgrimage site.
