Archeio-Marxism (Greek: αρχειομαρξισμός) was a radical left political movement that was active in interwar Greece.
The main motto of its supporters was "first education and then action" and they were against mass demonstrations and unionism.
They were named after the Archive of Marxism (Greek: Αρχείο Μαρξισμού) magazine, that was published in 1921.
Following Giotopoulos' quarrel with Trotsky in 1933-1934, the Archeio-Marxists left the ILO, and by the late 1930s, they became affiliated with the so-called "London Bureau", having formed the Communist Archio-Marxist Party of Greece.
The organization survived the repression of the Metaxas Regime, but its members came under increasing attack from both right-wing groups and the KKE-led EAM-ELAS resistance front at the end of World War II and during the Greek Civil War.
