Her son, Emperor Zhongzong, took over as emperor and reestablished the Tang Dynasty. Wu Zhao (624–705), also known as Empress Wu Zetian, was the first and only woman emperor of China. With her exceptional intelligence, extraordinary competence in politics, and inordinate ambition, she ruled as the “Holy and Divine Emperor” of the Second Zhou Dynasty (690–705) for fifteen years. Wu Zetian (624–705) was the only female emperor in China's history. She ruled the Tang Dynasty as empress (655–690), and then as Emperor for 15 years, in the seldom-mentioned Zhou Dynasty.
