Neo-Nazism is a general term for the related fascist, nationalist, white supremacist, and antisemitic beliefs and political tendencies of the numerous groups that emerged after World War II seeking to revive and reinstate Nazi ideology. Neo-Nazis employ their ideology to promote hatred and racial supremacy, to attack racial and ethnic minorities, and in some cases to create a fascist state. Some key features of neo-Nazism include:

• Beliefs: Neo-Nazis base their ideology on the notion of the racial superiority of white people, often referred to as the "Aryan" or white Nordic race, over all other races. They grade races in order of their alleged superiority, with black people and Jews at the bottom of the hierarchy. Homosexuals, Gypsies, and others are also condemned.

• Symbols: Neo-Nazis use symbols, terms, and ideology drawn directly from Nazi Germany and Holocaust-era fascist movements. These include Nazi flags and crosses, as well as code words such as "alien," "parasite," and "degenerate".

• Tactics: Some neo-Nazi groups emphasize simple hatred, while others are more focused on the revolutionary creation of a fascist political state. Neo-Nazism is a global phenomenon, with organized representation in many countries and international networks. Holocaust denial is common in neo-Nazi circles.

Neo-Nazis have adopted the trappings of Nazism, such as celebrating the birthday of Adolf Hitler, reading his book Mein Kampf, and performing the Nazi salute. They have also used other world events such as the COVID-19 pandemic, the "stealing" of the 2020 US presidential election, and the riots at the US Capitol to recruit people and as markers pointing to the coming revolution in global affairs. In response, neo-Nazi groups have developed a variety of ways to build bridges to more mainstream political and social movements.
