Irredentism

Irredentism is a political policy or guideline aimed at uniting irredentas—groups of people ethnically or historically related to one political system but under the control of a different polity—within ethnically or historically related territories. The word irredenta is Italian for “unredeemed” and was used by Italian patriots in the nineteenth and twentieth centuries who sought to liberate all Italian-speaking lands from foreign control. The hopes of these patriots, or irredentists, were basically fulfilled with the Treaty of Versailles that ended World War I. Modern examples of irredentist movements include the Bosnian War, Kurdish nationalism, and, according to some, the Russian annexation of Crimea.

In US politics, irredentist policies have come in many forms and guises. It is possible to view programs of racial or ethnic segregation as having irredentist intents. For example, African Americans could be restricted to a particular geographic area to keep intact an Irish American neighborhood. Another way that irredentism influences US politics is through the drawing of boundaries for electoral districts. Since 1812, political parties have redrawn electoral districts to favor the representation of one group over another. This gerrymandering, though ruled unconstitutional by the US Supreme Court in 1964, has been justified as a means of giving minority groups better political representation. It can also be seen in relation to Indigenous American relocation and subsequent land-claims suits and in US–Mexico border issues.

In 2014, the Russian annexation of Crimea led to conflict between Russia and Ukraine. In 2022, full-scale operations and warfare between the two nations began in a Russian attempt to regain more territory due to irredentist policies and beliefs. Though President Vladimir Putin claimed to be attempting to help citizens who had suffered abuse under Ukrainian rule, ultimately, these claims were never substantiated. Instead, critics have accused Putin of irredentism and wanting to take back territory that he views as a part of Russian rule.

In 2023, Hamas, the Islamic Resistance Movement, attacked civilians throughout Israel and took hundreds hostage in Gaza. Israel retaliated in response, and the conflict continued until 2025. While Israelis claim that Palestinian irredentism has been going on since the Jewish state was re-established in 1948 in an attempt to take back the land from Israel, Palestinians and critics of Israel have made similar claims against Israelis, particularly Zionist Jews who believe the land of Palestine is rightfully theirs.
