Introduction

The name Nakhon Pathom derives from the Pali Nagara Pathama, meaning First city, and is thus often referred as the oldest city of Thailand. It was already an important center during the Dvaravati kingdom from the 6th century until the 11th century, however it might even be older. Some historians speculate it dates back to the 3rd century BC, when Buddhist missionaries from India visited there.
Originally Nakhon Pathom Province contained a coastal city on the route between China and India, however due to the sedimentation of the Chao Phraya river the coast line moved away from the city. When the Tha Chin river changed its course, the city was removed from water and was deserted, the population moved to the new city of Nakhon Chaisi (or Sirichai). King Mongkut (Rama IV) moved the population back to the old city in 1870, after the restoration of Phra Pathom Chedi was finished. Archaeological exploration of this history has been scant.
Major movements of people into Nakhon Pathom province included emigration during and after the reign of King Buddha Loetla Nabhalai (Rama II) of Khmer villages (eg., Don Yai Hom village) Lanna (Baan Nua) and Lao Song villages (eg., Don Kanak village) as well as a major influx of Southern Chinese throughout the late 1800s and early 1900s. Currently Nakhon Pathom is attracting migration from other parts of Thailand, notably Bangkok and the Northeastern Thai and Burmese migrant workers. It's expansive borders include industrial zones, major university towns, government offices relocated from Bangkok and agricultural and transport hubs.
