PEAN was founded in October 1941 by Airforce officer Kostas Perrikos from Chios. Others involved in the group's founding were Ioannis Katevatis, G. Alexiadis, D. Papavasilopoulos. Members included Antonis Mytilineos, Mihalis Balitsaris, Spyros Galatis, N. Mourtos, Nikos Lazaris, Spyros Stanotas, Ioulia Bimba, Ekaterini Besi and others.
Its greatest accomplishment was the blowing up of the offices of ESPO (the collaborationist National Socialist Patriotic Organisation) at the corner of Patisia and Gladstone streets in Athens, on September 20, 1942. 43 Germans and 29 ESPO members were killed in the blast and ESPO - whose aim was to recruit Greeks in the Axis WWII effort - ceased to exist as an organisation.
