Nongbualamphu has a long and interesting history about 900 years back. The area was first known as Nongbualamphu Kabkaewbuaban and was a protectorate territory of Krungsrisatana ( Laos nowadays).
In 1574 the Thai King Maha-dharmaracha and his son (later to become King Naresuan) led a military expedition to invade Lan Chang ( Laos nowadays). Along the way, King Naresuan chose the area around Nongbua Reservoir as a place to rest his troops and prepare for the invasion of Laos. It was here that King Naresuan fell ill from small pox and had to return to Ayutthaya. A shrine was built in his honor at Nongbua Reservoir to commemorate the campaign and it has become an historical site.
In 1895, during the reign of King Rama III of Ratanakosin, the governor of Nong Khai Province appointed Phrawichay adomkamutaket to rebuild and resettle Nakhonkhuenkhan Kabkaewbuaban and the city's name was changed to "Munag Kamutsaiburiram"
In 1906, King Rama V appointed Phra Wicharnkamutkit to the governorship of the new city and changed its name to "Muang Nongbualamphu"
In 1907 Nongbualamphu became a district of Udon Thani province.Udon Thani was a large province with a population of over one million people. In accordance with the federal government's decentralization policy to promote better public service through more localization of government, the province of Udon Thani was separated into two provinces. And it became Nongbualamphu Province on December 1, 1993.
