The title was also given occasionally to another
woman of the same generation, while a woman from the previous generation was sometimes given the title of grand empress dowager (
Korean pronunciation: Tae Hwang Tae Hu;
Vietnamese: Thái Hoàng Thái Hậu) . Numerous empress dowagers held
regency during the reign of underage emperors. Many of the most prominent empress dowagers also extended their control for long periods after the emperor was old enough to govern. This was a source of political turmoil according to the traditional view of Chinese history.
