[Why] In the late Warring States, Chu's politics were corrupt and a sharp clash erupted between pro-Qin and pro-Qi factions. The patriotic minister Qu Yuan, advocating an alliance with Qi against Qin, suffered repeated slander and was exiled to the southern wilds by two successive kings. [What] The Qin general Bai Qi stormed the Chu capital Ying, burning the ancestral temples and overturning the realm. In exile, Qu Yuan threw himself into the Miluo River clutching a great stone to die for his country, leaving behind Li Sao, Nine Songs, and other Romantic masterpieces. [Who] Qu Yuan was the first great patriotic poet attested by name in Chinese history, his integrity and literary genius shaking the ages. King Huai and King Qingxiang of Chu were the foolish sovereigns who trusted petty men and ruined the state. [How] Qu Yuan's sacrifice founded the Chinese tradition of Romantic poetry and seeded the Chu Ci lineage. It gave birth to the two-thousand-year Dragon Boat Festival and became an unfading symbol of the national spirit.
