The Seven Grievances (Manchu: nadan koro; Chinese: 七大恨; pinyin: Qī Dà Hèn) was a manifesto announced by Nurhaci on the Thirteenth day of the Fourth lunar month in the Third year of Tianming era (Chinese: 天命; 7 May 1618). It effectively declared war against the Ming dynasty.
The seven grievances are:
After the announcement of the Seven Grievances, the attack on Fushun started. Han defectors played a massive role in the Qing conquest of China. Han Chinese Generals who defected to the Manchu were often given women from the Imperial Aisin Gioro family in marriage while the ordinary soldiers who defected were often given non-royal Manchu women as wives. The Manchu leader Nurhaci married one of his granddaughters to the Ming General Li Yongfang after he surrendered Fushun in Liaoning to the Manchu in 1618. The offspring of Li received the "Third Class Viscount" (三等子爵; sān děng zǐjué) title. In retaliation, a year later, a Ming punitive force of about 100,000 men, which included Korean and Yehe troops, approached Nurhaci's Manchus along four different routes. The Manchus scored successive victories, the most famous of which was near the town of Sarhu. The Ming dynasty was wearied by a combination of internal strife and constant harassment by the Manchu.
