Somdet Phra Ramesuan (1339–1395), son of king Ramathibodi I, reignw as the second and fifth king of the kingdom of Ayutthaya.
When King Ramathibodi ascends the throne of Ayuthaya, he sends King Ramesuan to reign in Lavo.
Upon King Ramathibodi's death in 1369, King Ramesuan travels to Ayutthaya to assume the throne, but holds it for less than a year before being deposed by his uncle, King Borommaracha I, the ruler of Suphanburi.
Sources differ over the nature of their conflict; official chronicles state that the older Boromaracha ruled with the willing consent of his nephew, while Jeremias van Vliet's Short History of Thailand indicates that Boromaracha's ascension came only after a bloody conflict bordering on civil war.
