The Progress Party was founded at a meeting at the movie theater Saga Kino in Oslo on 8 April 1973,[32] attended by around 1,345 persons.[32] The address was held by Anders Lange, after whom the party was named Anders Lange's Party for a Strong Reduction in Taxes, Duties and Public Intervention, commonly known as Anders Lange's Party, and abbreviated ALP.[33] Lange had some political experience from the interwar era Fatherland League, and was part of the Norwegian resistance movement during the Second World War.[32] Since the end of the war, he had worked as an independent right-wing political editor and public speaker.[32] Lange held his first public speech as chairman of ALP at Youngstorget in Oslo on 16 May the same year. ALP was to a large extent inspired by the Danish Progress Party,[34] which was founded by Mogens Glistrup. Glistrup also spoke at the event, which gathered around 4,000 attendees.[35]
