The Only One
Chinese history spans over four thousand years. In that time, exactly one woman held the title of Emperor. Not empress consort. Not regent. Emperor.
Wu Zetian (武则天, 624-705 CE) ruled China for fifteen years, founded her own dynasty (the Zhou), and died in her eighties having outlasted every rival, every conspiracy, and every attempt to write her out of history.
The traditional historical narrative treats her as a villain — ruthless, manipulative, willing to kill her own children for power. The revisionist narrative treats her as a feminist icon ahead of her time. The truth, as usual, is more interesting than either version.
The Concubine's Gambit
Wu entered the imperial palace at fourteen as a low-ranking concubine of Emperor Taizong. When Taizong died, she should have spent the rest of her life in a Buddhist convent, as was customary for former concubines.
Instead, she caught the attention of the new emperor, Gaozong — Taizong's son. This was scandalous. A father's concubine becoming the son's lover violated every Confucian norm. But Gaozong was besotted, and Wu was brought back to the palace.
What happened next is disputed. The traditional account says Wu strangled her own infant daughter and blamed the death on Empress Wang, Gaozong's wife. Whether this is true or slander invented by later historians who wanted to discredit her is genuinely unknowable. What is certain is that Empress Wang was deposed and Wu took her place.
The Power Behind the Throne
Gaozong suffered from debilitating headaches — possibly a brain condition — that left him increasingly unable to govern. Wu stepped in. By the 660s, she was effectively running the empire while Gaozong served as a figurehead.
She was good at it. She reformed the civil service examination system to reduce aristocratic privilege and open government positions to talented commoners. She expanded the empire's borders. She promoted Buddhism over Confucianism (partly because Confucian doctrine explicitly opposed female rule).
The Emperor
After Gaozong's death in 683, Wu ruled through two of her sons before dispensing with the pretense entirely. In 690, she declared herself Emperor of a new Zhou Dynasty.
The reaction was not what you might expect. There were conspiracies and rebellions, yes. But Wu had spent decades building a network of loyal officials, intelligence operatives, and military commanders. She had also cultivated popular support through tax relief and infrastructure projects.
She ruled for fifteen years. She was deposed in 705, at the age of eighty, in a palace coup. She died later that year.
The Blank Stele
Wu Zetian's tomb at Qianling contains a famous blank stele — a stone tablet with no inscription. The traditional explanation is that Wu left it blank deliberately, believing her achievements were too great for words. Another interpretation is that she left it for future generations to judge.
The stele remains blank today. After thirteen hundred years, nobody has agreed on what to write.
