I've seen this question pop up a few times, and I think there's some confusion floating around. There isn't a widely known novel or book literally called 'Is Kicked Out, She Came Back to Rule' that's based on a true story. The phrasing sounds exactly like one of those web novel or serialized fiction titles—you know the style, where the premise is right there in the name. It follows a super common trope in romance or revenge fantasy: the female lead gets exiled or betrayed, gains power, and returns to take over. It's a whole genre onto itself on platforms like Webnovel or Dreame.
Trying to pin down a 'true story' basis for a plot like this is tricky. The core idea—someone overcoming disgrace to reclaim their position—echoes historical figures or even modern business comeback tales, but the specific narrative of a woman being literally 'kicked out' and then returning as a ruler feels like pure fiction convention. If someone adapted a real biography into a novel with that title, it's incredibly niche. My guess is people are mixing up remembering a trope with recalling an actual book. Maybe they're thinking of a novelization of someone like Empress Dowager Cixi's rise, but even that doesn't perfectly match the 'kicked out' part.
Honestly, I'd be really curious if such a book did exist. The closest I can think of are those 'based on a true story' historical fiction books about monarchs, but they rarely have such blatantly dramatic titles. You'd get something more restrained like 'The Queen's Return' or similar. The title in question feels 100% like the digital serials I binge—pulpy, satisfying, and entirely fictional.
