I want to know the answer to the following question:
When did Tongzhi Emperor die?
All the background I'm provided with is that "She, the Empress Dowager Ci'an (who had been Xianfeng's empress), and Prince Gong (a son of the Daoguang Emperor), staged a coup that ousted several regents for the boy emperor.". Is that enough to answer the question?
Answer: no
