Liu Bang
Lou Jing (, later granted the royal surname Liu 刘), the architect of the policy, proposed granting the eldest daughter of Emperor Gaozu of Han to the Modu Chanyu of the Xiongnu. His proposal was adopted and implemented with a treaty in 198BC, following the Battle of Baideng two years prior. Wang Zhaojun, of the Han dynasty, and Princess Wencheng, of the Tang dynasty, are among the most famous heqin princesses.
