The term "alt-right" refers to a loosely connected far-right movement that emerged in the United States during the 2000s. It is characterized by its rejection of mainstream conservatism and its promotion of white nationalism, anti-immigration sentiments, and various conspiracy theories. The movement gained significant attention during the 2016 U.S. presidential election, particularly through its use of social media to spread its ideas. Members of the alt-right often utilize online platforms to share their views and organize events. Key figures associated with the movement include Richard Spencer and Milo Yiannopoulos. The alt-right has been criticized for its extremist views and has been linked to various incidents of hate speech and violence.
