delegitimize

Delegitimize is a verb meaning to strip of or challenge the legitimacy of a person, government, institution, movement, or idea. To delegitimize an actor is to argue that it lacks the authority, right, or moral justification to act or be treated as legitimate. The term derives from legitimate and the prefix de-, indicating removal or reversal of legitimacy.

In political science and public discourse, delegitimization can occur through rhetorical framing, normative claims about origins or consent, legal challenges, or shifts in recognition by authorities and the public. Common targets include governments, political parties, electoral processes, courts, or international bodies. The aim may be to weaken support, reduce compliance, or justify opposition actions.

Effects can include erosion of public trust, decreased legitimacy in governance, sanctions, or changes in recognition by other states or institutions. Critics argue that delegitimization can be used as a political tool to suppress dissent or to portray opponents as illegitimate without addressing substantive issues, potentially undermining legitimate debate or democratic processes. Proponents may view it as a necessary check on power when authorities act unlawfully or immorally.

Related terms include legitimacy, illegitimacy, and delegitimization, as well as concepts such as legitimacy crisis, protest, or disinformation. Notable contexts involve electoral integrity, regime change, and international recognition.
