The 20th-century German Nazi Party made extensive use of graphic symbols, especially the swastika, notably in the form of the swastika flag, which became the co-national flag of Nazi Germany in 1933, and the sole national flag in 1935. A very similar flag had represented the Party beginning in 1920.

Neo-Nazism comprises the post–World War II militant, social, and political movements that seek 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.
