History

The name Uttaradit means northern landing, as it was formerly a trade center on the Nan river.

In the Sukhothai era several city state (Mueang) controlled by the King in Sukhothai were located in the area of the modern province. Mueang Fang was located in modern day Mueang Uttaradit district, Mueng Thung Yang in Lablae, Mueang Ta Chuchok in Tron district.

Later in the Ayutthaya kingdom Mueang Phichai was one of the 16 main Mueang of the kingdom. During the reign of King Naresuan the ruler of Phichai together with the ruler of Sawankhalok revolted. After their revolt was suppressed by the King the population of both cities was forced to move to Phitsanulok.

During the war with the Burmese after the fall of Ayutthaya, Phichai was the site of several battles. The ruler of Phichai succeeded to fight back the Burmese and was awarded with the title Phraya Phichai Dabhak.

During the reign of King Rama III Mueang Phichai controlled several Mueang of northern Siam like Nan or Phrae, and even Luang Prabang and Vientiane. At the point where the Nan river became shallow a port was established. As this town grew in importance as an important trade point, in 1887 it was made a Mueang subordinate of Phichai. 1899 the center of Phichai was moved to this new location, which was renamed to Uttaradit in 1915.
