I read a fictional story before where an empress was wrongly accused of black magic. The emperor loved her so much but the investigation didn't go deeper because the ministers were trying convince the emperor to just dethrone her which he did. After few years, he made his own investigation and he found out that his imperial royal consort did the planning and the story goes on.
At the end, the former empress was called and asked to be the emperor's empress again. My question is, can A dethroned empress be empress again if the allegations and accusations are proven wrong?
