Nakhon Sawan province
Nakhon Sawan (, ) is one of Thailand's seventy-six provinces (changwat). It lies in lower northern Thailand, neighbouring Kamphaeng Phet, Phichit, Phetchabun, Lopburi, Sing Buri, Chai Nat, Uthai Thani, and Tak (clockwise from north).

Toponymy
The word nakhon originates from the Sanskrit word nagara meaning 'city', and the word sawan from Sanskrit svarga meaning 'heaven'. Hence the name of the province literally means 'city of heaven' or 'heavenly city'.

History
Nakhon Sawan province was a city since Dvaravati era. While part of the Sukhothai Kingdom, it was called Mueang Phra Bang, the southern frontier city of Sukhothai. Later within the Ayutthaya kingdom it was an important trade center because of its location at the two major rivers from the north. It also was the common meeting point of Burmese troops before moving to attack Ayutthaya. In the reign of King Taksin the Great, Phra Bang became a Siamese military base to prevent further Burmese attacks.

When King Mongkut signed the Bowring Treaty with Britain the glorious time of Nakhon Sawan began, as it became the main rice and teak trading centre. However the opening of the northern railway in 1922, the economic crisis before 1932 revolution, and finally the opening of Dejativongse bridge and Phahonyothin highway in 1950 each decreased the importance of water transportation and thus made Nakhon Sawan less important.

When in 1895 King Chulalongkorn established the monthon as part of the Thesaphiban administrative reform, Nakhon Sawan became capital city of Monthon Nakhon Sawan.

The 4th Infantry Regiment of the 3rd Area Army is based in Nakhon Sawan. It is responsible for defending the northwestern border with Burma, from Mae Hong Son in the north to Kanchanaburi in the south.
