Yi Yin and Taijia
He caged his king for three years, then handed back the throne whole: Chinese political ethics at its boldest.

From kitchen to court
Yi Yin had helped Tang destroy Xia and found Shang — the founding minister of the dynasty. After Tang’s death the throne passed among his sons, and Taijia, Tang’s grandson, came to the throne young and untried.
Within three years Taijia did what every old minister dreads: he broke Tang’s laws. The records call him benighted, violent, disorderly — trampling his grandfather’s rules with a tyrant’s temper.
A decision audacious past believing
Yi Yin did the boldest thing in Chinese political history: he exiled the king.
Taijia was sent to the Tong palace, beside Tang’s tomb, to mourn and reflect at his grandfather’s grave; Yi Yin governed as regent. This is Yi Yin exiles Taijia.
Feel how astonishing it is: a minister caged his sovereign — and did not usurp. Yi Yin’s explanation to the court: left alone, Taijia will destroy Tang’s achievement; set beside the founder’s tomb, he will face the founder’s rules every day. For three years Yi Yin held the state and waited for the king to grow.
Repentance, return, a good king
Taijia lived three years at Tong. Facing his grandfather’s tomb daily, hearing elders tell how Tang opened the nets on three sides and founded the dynasty, the young king slowly understood what an inheritance meant.
The record says he repented, blamed himself, and turned to good. Yi Yin personally brought the crown and robes, restored him fully to power, and withdrew. Taijia ruled with virtue, the lords submitted, and he became a model king.
In one exile and one return, both king and minister passed their examination.
A rival version, and the meaning
The story has a disturbing twin: the Bamboo Annals claims Yi Yin usurped, and Taijia, slipping out after seven years, killed him. The sources point opposite ways, and the Tsinghua bamboo texts reveal still earlier strata of the Yi Yin legend. Which is true remains unanswered.
But the story’s afterlife is beyond doubt: it scripted Chinese political ethics — a minister may take drastic measures against a failing ruler, provided he gives power back. Huo Guang deposing a Han prince, every later regent’s tale, imitates Yi Yin. Whenever states outweigh rulers was argued, the case began here.
