Identitarianism was a far-right and ultranationalist political ideology which originated in Europe due to concerns about the North African and Middle Eastern migrant crisis and the "Great Replacement" theory during the 2010s. The movement was a backlash against rising multiculturalism in European countries starting in the 1990s, and its roots dated back to the rise of the "New Right" in France in response to the influx of Muslim Algerians after the end of the Algerian War in 1962. During the 2010s, right-wing populism's popularity in Europe surged due to the migrant crisis caused by the rise of the Islamic State in Iraq and Syria, the Syrian Civil War, the Second Libyan Civil War, and deterioration in the economic conditions of several African and Middle Eastern nations. While Sweden welcomed migrants into the country, Hungary declared a state of emergency and closed its borders. That same year, a series of deadly terrorist attacks struck the heart of Europe. Ten days after the November 2015 Paris attacks, Sweden announced that the country would restrict its borders, but it quickly became overwhelm, having taken in more immigrants than any other countries in Europe. The far-right turned Sweden into a symbol of chaos and destruction of American culture, accusing the migrants of being responsible for an increase in sexual assaults and criminal activities. However, in 2019, thousands took to the streets of Europe and demanded one Europe for everyone, and, in the year's European Parliament elections, the liberals and greens made huge progress, while, in the Swedish general election, the far-right Sweden Democrats gained parliamentary representation, but less than expected.
