Regime change is the partly forcible or coercive replacement of one government regime with another. Regime change may replace all or part of the state's most critical leadership system, administrative apparatus, or bureaucracy. Regime change may occur through domestic processes, such as revolution, coup, or reconstruction of government following state failure or civil war. It can also be imposed on a country by foreign actors through invasion, overt or covert interventions, or coercive diplomacy. Regime change may entail the construction of new institutions, the restoration of old institutions, and the promotion of new ideologies.
According to a dataset by Alexander Downes, 120 leaders were removed through foreign-imposed regime change between 1816 and 2011.
Regime change can be precipitated by revolution or a coup d'état. For example, the 1917 Russian Revolution, the 1962 Burmese coup, and the 1979 Iranian Revolution.
Foreign-imposed regime change is the deposing of a regime by a foreign state, which can be achieved through covert means or by direct military action. Interstate war can also culminate into a foreign-imposed regime change for the losers, as occurred for the Axis Powers in 1945. Foreign-imposed regime change is sometimes used by states as a foreign policy tool. According to a dataset by Alexander Downes, 120 leaders have been successfully removed through foreign-imposed regime change between 1816 and 2011.
During the Cold War, the United States frequently intervened in elections and engaged in attempts at regime change, both covertly and overtly. According to Michael Poznansky, covert regime change became more common when non-intervention was codified into international law, leading states that wanted to engage in regime change to do so covertly and conceal their violations of international law.
