Ram Khamhaeng
In 1239, the Tai governor of Sukhothai rebelled and declared independence from Lavo – giving birth to the Sukhothai Kingdom. In Northern Thai chronicles Lavo is called “Khom”, and during the 13th century the Lavo kingdom shrank swiftly due to the expansion of Sukhothai under Ram Khamhaeng the Great, retreating to its heartland around Lavo and Ayodhaya.
