Hồ Quý Ly
In 1401, he abdicated in favor of his second son Hồ Hán Thương, who also the grandson of Tran Minh Tong. In accordance with the former Trần dynasty's tradition, Hồ Quý Ly styled himself as Emperor Emeritus and still possessed much power over state affairs. From 1400 to 1403, Hồ Quý Ly and his son, Hồ Hán Thương sent three expeditions against Champa. The first and third expeditions ended with Champa's defensive victory; however the second one (1402) resulted in the Champa King Jaya Simhavarman V relinquishing southern Quảng Nam and northern Quảng Ngãi to Dai Viet.
