Empress Dowager Longyu
At the early stages of the rise of Qing empire, the Haixi Jurchens played an important and antagonistic role. The Jianzhou Jurchens which later become the ruler of Qing China had bitter relationships with the Haixi Jurchens. Eventually, the Hada clan were defeated by the Jianzhou Jurchens in the year of 1601 marking the end of its independence. Another notable clan Yehe resisted the Jianzhou Jurchens longer with failed attempts of seeking alliance with Ming dynasty (Since both Haixi and Ming are decisively defeated by Jianzhou and were not able to even up the odds). In 1619, Jianzhou Chieftain Nurhaci besieged the seat of Haixi Chieftain Gintaisi. Gintaisi died during the siege while leaving a famous curse "Even if there is only one daughter left in my clan, I will overthrow the Manchus!". The curse was arguably fulfilled by his direct descendant, Empress Dowager Cixi, who usurped power from the house of Aisin-gioro and became the de facto ruler of China. The curse was also fulfilled by Empress Dowager Longyu, a descendant of Gintaisi, and the one who eventually signed Puyi's abdication from the throne, thus ending the Qing dynasty.
