History
Suphan Buri might be the site of the legendary Suvarnabhumi, which is mentioned in very old Buddhist writings. However the first confirmed historical settlement was in the Dvaravati period, when the city was known as Mueang Thawarawadi Si Suphannaphumi ('the Dvaravati city of Suvarnabhumi'). Its founding took place c. 877–882. In the era of Ankorian king Jayavarman VII, an inscription called Prasat Phra Khan (จารึกปราสาทพระขรรค์) was made which mentions the name of Suvarnapura. Later it was called U Thong, and was once believed to be the home city of Prince U Thong, the founder of the Ayutthaya Kingdom. King Khun Luang Pha Ngua gave it the current name. Suphan Buri was a border city, and the site of several battles with the neighbouring Burmese.

Suphan Buri people speak in a distinct Central Thai dialect, which is believed to be the form spoken during the Ayutthaya period.
