Vacalopoulos 1976, p. 211: "The earliest origins of the armatoles are lost in the murk of history. However, in my Origins of the Greek Nation, an analysis of various sources not previously sifted in any thorough way suggested that the institution first appeared in Thessaly during the reign of Murad II (1421–1451), specifically in the Agrafa, Thessaly. From there, it subsequently spread to other parts of the Hellenic world, though not to the Peloponnese." Vacalopoulos, Apostolis (1976). The Greek Nation, 1453–1669.

Vacalopoulos 1961, p. 333: "Οί πυρήνες τών μαχητικών του δυνάμεων είναι οί άρματολοί καΐ οί κλέφτες...ν'άποτελέσουν τήν «μαγιά της λευτεριάς», όπως παραστατικά λέγει ό άγωνιστής τοϋ 21 Γιάννης Μακρυγιάννης."

Vacalopoulos 1976, p. 212: "The district over which the armatoles' authority extended was called an armatoliki. Commanders were known as capetanos or capetanios (from the Italian capitano), the rank and file as pallikaria (from the ancient Greek pallix, -ikos), and section leaders as protopallikara."
