In Germany, he was acquainted with Georgios Skliros[2] who introduced Glinos to socialist ideology and had decisive effect on his later career.

His efforts were stopped, and his reforms undone when Venizelos lost power in 1920, and Glinos began publishing under the pseudonym "A. Gabriel, teacher".

After the establishment of the Metaxas Regime, along with many other Communists and other political dissidents, he was sent to internal exile on the island of Agios Efstratios.

During the Axis Occupation of Greece, Glinos became actively involved in the founding of the Communist-led National Liberation Front (EAM), and wrote its political manifesto, What is the National Liberation Front, and what does it want (Τί είναι και τί θέλει το ΕΑΜ) in September 1942.

Glinos died during Christmas of 1943, after an operation and while he was preparing to move to Free Greece, in order to participate in the foundation of the "Mountain Government" and possibly take the position of its President.
