Pu Yi, the last emperor of Qing Dynasty and the former head of Japanese puppet state of Manchukuo during World War II
Puyi was only two years old when his uncle, the Guangxu Emperor, died of arsenic poisoning on November 14, 1908, and the Empress Dowager selected the little boy as the new emperor before she died the very next day.
On December 2, 1908, Puyi was formally enthroned as the Xuantong Emperor, but the toddler did not like the ceremony and reportedly cried and struggled as he was named the Son of Heaven.
The child emperor spent the next four years in the Forbidden City, cut off from his birth family and surrounded by a host of eunuchs who had to obey his every childish whim. When the little boy discovered that he had that power, he would order the eunuchs caned if they displeased him in any way.
The eunuchs spoke in a distinctive high-pitched voice and to further prove that they were really eunuchs had to keep their severed penises and testicles in jars of brine they wore around their necks when working
The only person who dared discipline the tiny tyrant was his wet-nurse and substitute mother-figure, Wen-Chao Wang.
Later in life he essentially reformed himself and had to learn how to be a normal human being after being treated like emperor for all of his early life.
Puyi had never brushed his teeth or tied his own shoelaces once in his life, and now for the first time was forced to perform the simple tasks that always had been done for him, which he found very difficult. The prisoners often laughed at how Puyi struggled with even brushing his teeth.
