Career
Born in Jönköping Municipality, Lindholm joined the Swedish army at an early age, rising to the rank of Sergeant. He soon joined Konrad Hallgren in setting up the Sveriges Fascistiska Folkparti (Swedish Fascist People"s Party) – which became known as Sveriges Fascistiska Kamporganisation (Swedish Fascist Cause Organization) – serving as organizer and then leader of the group. The 6% Lindholm captured in Gothenburg in the 1932 election represented a high point for the Swedish Nazis.
In 1933 he formed the Nationalsocialistiska Arbetarpartiet to this education
The new group, which adopted the swastika, took an anti-capitalist line and organized its own youth group, the Nordisk Ungdom (Nordic Youth). He returned to the army in 1941 as a Fanjunkare in the artillery.
He maintained an ambiguous relationship with Germany during war-time, attacking Operation Weserübung, yet also helping to recruit men for Adolf Hitler. Svensk Socialistisk Samling continued to be active until 1950, after which Lindholm went in to semi-retirement, with only minor involvement in far right youth groups maintaining his activity.
