On returning home, Razadarit besieged Prome, and when Minhkaung came down to relieve it, defeated him so severely that he sued for terms. The two kings swore eternal friendship, mounting the steps of the Shwehsandaw pagoda, Prome, together hand in hand, and entering into a marriage alliance. Razadarit granted Minhkaung the customs revenue of Bassein; this, and the fact that throughout the fifteenth century Tharrawaddy was subject to Prome and was held by a governor who was appointed, at least nominally, by Āva, suggest that one cause of the fighting was the need of Āva to trade along the Irrawaddy river as far south as possible.
