高皇后
Empress (Dowager) Lü Zhi (241–180 BC), commonly known as Empress Lü () and formally Empress Gao of Han (), was the empress consort of Gaozu, the founding emperor of the Han dynasty. They had two known children, Liu Ying (later Emperor Hui of Han) and Princess Yuan of Lu. Lü was the first woman to assume the title Empress of China and paramount power. After Gaozu's death, she was honoured as Empress Dowager and Regent during the short reigns of Emperor Hui and his successors Emperor Qianshao of Han and Liu Hong (Emperor Houshao).
