和帝
Empress Dou (, personal name unknown; 63–97 CE), formally Empress Zhangde (, literally "the polite and virtuous empress"), was an empress of the Chinese Han dynasty. Her husband was Emperor Zhang. She was already influential during her husband's reign, but became particularly powerful as empress dowager regent between 88 and 92 for her adoptive son Emperor He after Emperor Zhang's death. Her family members, particularly her brother Dou Xian, became extremely powerful, until they were toppled in a coup d'etat by Emperor He, in 92. Empress Dou lost her power, but remained honored until her death.
