Trần Thánh Tông
Trần Thánh Tông had one consort, Empress Thiên Cảm Trần Thiều, the fifth daughter of his uncle Trần Liễu. Thánh Tông's first son, Trần Khâm, was born on November 11, 1258 (in the lunar calendar), only eight months after the Emperor's enthronement; he was entitled as Crown Prince in December 1274. His second son, Prince Tá Thiên Trần Đức Việp, was born in 1265. Trần Thánh Tông's only daughter was Princess Thiên Thụy, who married to Prince Hưng Vũ Trần Quốc Nghiễn, son of Trần Quốc Tuấn. She had an adulterous affair with General Trần Khánh Dư, which almost led to the latter's death by order of the Emperor. Princess Thiên Thụy and her younger brother Trần Nhân Tông died on the same day, November 3, 1308 (in the lunar calendar).
