Empress Deng Sui

Empress Deng Sui (鄧綏) (AD 81–121), formally Empress Hexi (和熹皇后, literally "the moderate and pacifying empress") was an empress during Han Dynasty. She was Emperor He's second wife. She later, as empress dowager, served as regent for his son Emperor Shang and nephew Emperor An, and was regarded as an able and diligent administrator. She was perhaps the last effective ruler of the Eastern Han Dynasty, as the subsequent emperors and empresses dowager were largely incompetent rulers. During her regency, there were natural disasters and wars with Xiongnu and Qiang, but she was able to remedy the disasters and largely quell the wars. She was also praised for her attention to criminal justice.
