Lavo

Lavo was a kingdom of the lower Chao Phraya basin, centred on Lavapura, or Lopburi. It began as a Mon city; by 1337 it was among the plain's competing Thai-speaking polities, with its seat having shifted downstream to Ayodhya.

In 1351 the Lavo line joined Suphannaphum to found Ayutthaya, and Lavo became a princely seat. King Ramesuan withdrew there after losing Ayutthaya in 1370 and retook it in 1388. Lopburi later declined until King Narai rebuilt it as a second capital in the decade beginning in 1660.
