The alt-right is a far-right, white nationalist movement. A largely online phenomenon, the alt-right originated in the United States during the late 2000s before increasing in popularity and establishing a presence in other countries during the mid-2010s, and has been declining since 2017. The term is ill-defined and has been used in different ways by academics, journalists, media commentators, and alt-right members themselves.
Prominent alt-rightists were instrumental in organizing the August 2017 Unite the Right rally in Charlottesville, Virginia; pictured are rally participants carrying Confederate battle flags, Gadsden flags, and a Nazi flag.
