Trần Nhân Tông

Trần Nhân Tông (Trần Khâm; 1258–1308), the third Trần emperor, ruled Đại Việt from 1278 to 1293. As the Yuan threat grew, he and retired emperor Thánh Tông gathered the court in 1282 to discuss war and appointed Trần Quốc Tuấn commander-in-chief in 1283.

They led resistance to the Yuan invasions: after defeats in 1285, their forces won at Hàm Tử and Chương Dương and retook Thăng Long, and in 1288 Trần Quốc Tuấn destroyed the Yuan fleet at Bạch Đằng.

After abdicating to his son Trần Thuyên in 1293 he became a monk in 1295 and founded the Trúc Lâm school. In 1306 his daughter Huyền Trân married the Champa king for two provinces.
