At a given point in time a royal dynasty or noble house may seem unassailable, both militarily and politically, yet find itself sidelined by defeat in battle or outmaneuvering in court. For the purpose of this thread I am excluding cases of foreign aggression, such as Alexander of Macedon's conquest of Persia. I am looking for examples where a ruling dynasty or preeminent noble house was knocked off its high seat by domestic opposition within five years or less. For ATL purposes we can consider instances where this nearly occurred but was narrowly averted OTL.
Edit: The period of time I'd like to focus on is 1200-1500AD
