Stieg Larsson [SEP] Activism and journalism
While working as a photographer, Larsson became engaged in far-left political activism. He became a member of "Kommunistiska Arbetareförbundet" (Communist Workers' League), edited the Swedish Trotskyist journal "Fjärde internationalen", journal of the Swedish section of the "Fourth International". He also wrote regularly for the weekly "Internationalen". Larsson spent parts of 1977 in Eritrea, training a squad of female Eritrean People's Liberation Front guerrillas in the use of mortars. He was forced to abandon that work, having contracted a kidney disease. Upon his return to Sweden, he worked as a graphic designer at the largest Swedish news agency, Tidningarnas Telegrambyrå, between 1977 and 1999.
