Unless otherwise indicated, the information in this section is based on local Pai resident Thomas Kasper's history of Pai:
The area of modern-day Pai has been inhabited for more than 5,000 years. About 2,000 years ago, the Lua (or Lawa) Tribe was the dominant ethnic group all over the area of today's northern Thailand, and a few of their descendants still live in villages only about 20 km away from Pai.
The recorded history of the area starts about 800 years ago with the establishment of a settlement (today known as Ban Wiang Nuea) about 3 km north of modern-day Pai. Ban Wiang Nuea was founded in 1251 AD by Shan immigrants from the region of modern-day northern Burma. Due to the area's remoteness and seclusion, people in those times were mainly cut off from news of the outside world and therefore not much concerned with the politics of Lanna and the rest of Thailand.

The result was a conflict that eventually led to a series of wars over territorial dominance in the Pai area. The Lanna troops finally defeated the Shan soldiers in 1481, forcing them to retire to Burmese territory. The Shan families who had lived in the area for a long time, establishing households, farming their land and raising their families, were granted permission to stay by the Lanna prince, along with a certain degree of cultural and social autonomy under the law and authority of the Lanna kingdom. Ban Wiang Nuea as a result became a village sharply divided into two parts by a wall into a "Shan" part and a "Lanna" part.
In the second half of the 19th century, colonial powers France and England, who had already established their influence in Vietnam, Cambodia, Laos and Burma, were
