History of Lopburi Province : Lopburi is a city with a long history because there are traces of human habitation since the prehistoric era, no less than 3,000-4,000 years ago from the discovery of a large amount of archaeological evidence and there is documentary evidence and inscriptions mentioning Lopburi in many ways, for example in the 11th-15th Buddhist centuries , there is evidence, namely the Northern Chronicles, mentioning that Phraya Kanwarndis sent a Brahmin army to build the city of Lavop since 1002 BE.
There is also the Chinkalamaliphakorn legend that mentions the establishment of Hariphunchai city in 1204 CE. Two years later, in 1206 CE,an envoy was sent down the Ping River to Lavapura city to ask for the descendants of the Lavapura king to rule. The Lavapura king then granted his daughter, Queen Chamadevi, to rule Hariphunchai city. The name of Lavapura city in the Chinkalamaliphakorn legend is accepted as the current Lopburi city. Therefore, it can be concluded that Lopburi must have been an important city. Other kingdoms accepted it and asked for descendants to rule.
During the period from the 16th to the 18th Buddhist century , Lavo or Lopburi occasionally fell under the authority of the Kingdom of Cambodia. Towards the end of the 18th Buddhist century , there was weakness in the Kingdom of Cambodia, causing the states that were once under its authority to become independent, including Lavo. In the 19th Buddhist century , evidence appeared that Lopburi was likely the city where King U Thong had ruled before moving to establish the Ayutthaya Kingdom.
It was during the Ayutthaya period that Lopburi flourished the most because King Narai the Great (reigned 1656-1688) established Lopburi as the second capital. After the reign of King Narai the Great, Lopburi lost much of its importance until the reign of King Rama IV of the Rattanakosin period, who established Lopburi as another place of residence. Therefore, it can be seen that Lopburi has been important for thousands of years.
