How might a king removed from power be dangerous to the republic?

A king removed from power can pose a significant threat to the republic by rallying loyalists and inciting unrest or rebellion among the populace who still support him. His influence and resources may be leveraged to destabilize the new government, undermining its authority and legitimacy. Additionally, his potential to create divisions within society can lead to civil strife, weakening the republic's cohesion and governance. Ultimately, a deposed monarch may inspire attempts to restore the old regime, jeopardizing the republic's stability and democratic ideals.
