By the 5th century the capital of this kingdom was moved south to Lavo (present day Lopburi province).

A city named Ban Tak was established by Jamadevi (พระนางจามเทวี), princess of the Lavo kingdom, around 663 CE.

It became part of the Sukhothai kingdom through battles led by Ramkhamhaeng the Great and formed the main fortress on the western front.

The city was moved further west and renamed Mueang Rahang when the Ayuthaya kingdom was lost to Burma during King Maha Thammaracha's reign.
