Today, many countries around the world are nation-states: sovereign political entities in which one “nation” (a particular ethnic, cultural, or linguistic group) comprises a large majority of a country’s population. In a way, it does make sense; after all, it is easier to communicate with people who speak the same language as you. But some issues do arise: what about people groups who fall outside of the “nation”? What if members of your “nation” live outside of your country’s borders? Despots of all creeds have answered these questions with the same response: genocide and irredentism.
Irredentism is defined in the Free Dictionary as “a national policy advocating the acquisition of some region in another country because of common linguistic, cultural, historical, ethnic, or racial ties.” This is a fair description of Russia’s and China’s “national policy” towards Ukraine (especially Crimea and the other Russian-majority areas of the country) and Taiwan, respectively. Putin has been loudly proclaiming the Russian people’s historical rights and interests in that country whilst denying that the Ukrainians even exist as a distinct people. Meanwhile, the People’s Republic of China is building up its military to potentially invade the island of Taiwan, which the Beijing government regards as a breakaway province.
Both geopolitical crises have the potential to spiral into a new global conflict, and this threat has historical precedence. Irredentism is the intersection between ethnonationalism and war, as irredentist movements can spiral from a “political talking point” to an invasion.
National unification appeals to people who oppose an irredentist regime, hence irredentism’s political usefulness to dictators. In Russia, for example, Putin’s popularity increased following the annexation of Crimea. Irredentist regimes thrive in an environment of perceived persecution, whether the Germans in the Sudetenland or Russians in the eastern and southern Ukraine, so the irredentist can claim that the invasion of a neighbouring country can be justified as “helping your own”.
