Empress Dowager Longyu
A popular legend says that Gin Taisi, the last prince of East Yehe, upon defeat by Nurhaci, cursed that the Yehe Nara will be the downfall of the Aisin Gioro clan, even if there's only Yehe Nara daughters left. This curse was supposedly fulfilled with Empress Dowager Longyu who formally abdicated on the behalf of Puyi leading to the end of the Manchu dynasty.
