陳仁宗
The mutual struggle against the Mongols brought Đại Việt and Champa closer together. Thus, the Đại Việt emperor Trần Nhân Tông married off his daughter, Huyen Tran, to Chế Mân in exchange for the provinces of O and Lý. His other "first rank wife", or "first queen", was Princess Bhaskaradevi, though he also married a princess from Java, Queen Tapasi.
