List of Greek Resistance organizations

During the period of the Axis Occupation of Greece in the Second World War, a multitude of Resistance organizations sprang up. A May 1943 report of the Intelligence Bureau of the Greek government in exile mentioned 33 active groups, a number that increased to 79 in a joint British report of 17 October 1943. According to some sources, the number was as high as 140. These numbers include groups of vastly different natures, which can be roughly divided in three categories: the major organizations, which displayed significant regional or nationwide action, including guerrilla operations against the Occupation authorities; the small political groupings, mainly active in Athens, with a limited following and engaged mainly in political propaganda and small-scale sabotage; and a small number of groups focused on intelligence and sabotage operations, in direct cooperation with the British secret services in the Middle East.
