The National Policy Institute (NPI) was a white nationalist/white supremacist think tank and lobbying organization founded in 2011 by Richard B. Spencer, a prominent figure in the alt-right movement. Headquartered in Alexandria, Virginia, NPI promoted 'racial realism' and identitarian policies, advocating for white nationalist ideologies under the guise of intellectual discourse. The organization published reports, hosted conferences, and lobbied for policies aligned with white supremacist interests, including opposition to immigration and multiculturalism. Spencer served as its president, using NPI as a platform to network with far-right activists and influence broader alt-right narratives during the 2010s. NPI gained notoriety for its role in organizing events tied to extremist rhetoric, such as the 2016 National Policy Conference where attendees performed Nazi salutes and chanted 'Hail Trump' in response to Donald Trump's election victory. The group faced significant backlash, including deplatforming from venues and financial institutions, and was criticized by organizations like the Southern Poverty Law Center for advancing hate ideologies. By 2019, amid legal and financial pressures—including a lawsuit from the Southern Poverty Law Center over doxxing allegations—Spencer announced the dissolution of NPI, stating it had fulfilled its purpose. The organization's legacy includes amplifying alt-right influence in U.S. politics.
