Page "Nakhon Sawan Province" Paragraph 3

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 center.

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.
