 A collaborationist government was installed, but its authority with the Greek people was minimal, and its control over the country compromised by the occupation authorities, who created a patchwork of separate jurisdictions.As early as the autumn 1941, the first stirrings of a resistance movement were registered, with attacks on isolated Gendarmerie stations in Macedonia in northern Greece.The establishment of large-scale resistance organizations, most notably the communist-dominated National Liberation Front (EAM) and its military wing, the Greek People's Liberation Army (ELAS), which proceeded apace in 1942, began to challenge not only the collaborationist government's organs, but also the Italian occupation troops.
