NDU was formed during spring 2002 and has taken a strong stance against multiculturalism, communism, homosexuality and feminism striving for a nation characterized by Nordic culture, tradition and national solidarity.
In 2003 the organisation performed a violent attack against the Gay pride-festival in Stockholm, where they began throwing bottles and beating the participators of the parade, this later resulted in the imprisonment of the chairman Marc Abramsson on the terms of battery and rioting.
