Lop Buri has been a town of cultural diversity and continuity for more than 3,000 years since the pre-historic period. It is a place where a lot of historical evidence has been discovered. During the Dvaravati period (the 6th - 11th century), Lop Buri had been under the control of the Mons and Khmers until the 14th century when the Thai possessed more power in this land. During the reign of King U Thong, the first king of Ayutthaya, Lop Buri was the Mueang Luk Luang - the prince’s town.
King U Thong appointed Phra Ramesuan, his eldest son to rule Lop Buri in 1350. When King U Thong passed away in 1369, the prince had to give the throne to his uncle who ascended to the throne with the royal name of “Phra Borom Rachathirat I”. The prince still governed Lop Buri afterwards. In 1388, Phra Borom Rachathirat I passed away and Phra Ramesuan went to the throne in Ayutthaya for the second time.
