Lê Hoàn
The fifth prince Duke of Khai Minh, Lê Long Đĩnh, nominated himself as crown prince. According to the Đại Việt sử ký toàn thư, Lê Hoàn viewed him as the favourable to become the next emperor, but royal court mandarins suggested him not to do it because they viewed other candidates as more viable. Lê Hoàn followed the advice and chose his older brother Lê Long Việ, the duke of Nam Phong.
