Phrip Phri

Phrip Phri (Thai: พริบพรี) or Srijayavajrapuri, later known as Phetchaburi, was a Xiān political entity located on the west coast of the Bay of Bangkok, lower central Thailand. It was established in the 12th century by a royal Pprappanom Tteleiseri from Soucouttae/Locontàï. Previously, the city was a maritime-oriented port on the ancient trade route between India and China during the Dvaravati period, but was abandoned around the 11th century following the decline of the Dvaravati civilization.

In the 12th century, Phrip Phri was possibly under Lavo's Ayodhya since several royals from Ayodhya were appointed the rulers of Phrip Phri, as mentioned in local chronicles and legends. It then became the vassal of the emerging Siamese Sukhothai and later formed part of the Ayutthaya kingdom in 1351, which made it functioned as a significant fortified frontier of Ayutthaya.
