Anti-imperialismAnti-imperialism in political science and international relations is a term used in a variety of contexts, usually by nationalist movements who want to secede from a larger polity (usually in the form of an empire, but also in a multi-ethnic sovereign state) or as a specific theory opposed to capitalism in Leninist discourse, derived from Vladimir Lenin's work Imperialism, the Highest Stage of Capitalism. Less common usage refers to opponents of an interventionist foreign policy.
Russian imperialismRussian imperialism includes the policy and ideology of power exerted by Russia, as well as its antecedent states, over other countries and external territories. This includes the conquests of the Russian Empire, the imperial actions of the Soviet Union (as Russia is considered its main successor state), as well as those of the modern Russian Federation. Some postcolonial scholars have noted the lack of attention given to Russian and Soviet imperialism in the discipline.
American imperialismAmerican imperialism is the expansion of American political, economic, cultural, media and military influence beyond the boundaries of the United States. Depending on the commentator, it may include imperialism through outright military conquest; gunboat diplomacy; unequal treaties; subsidization of preferred factions; regime change; or economic penetration through private companies, potentially followed by diplomatic or forceful intervention when those interests are threatened.
EmpireAn empire is a political unit made up of several territories and peoples, "usually created by conquest, and divided between a dominant center and subordinate peripheries". The center of the empire (sometimes referred to as the metropole) exercises political control over the peripheries. Within an empire, different populations have different sets of rights and are governed differently.
