Upon his return to Greece, he submitted a proposal for an educational reform to the government in 1913. He proposed introduction of, and changes to:
The language of instruction (using colloquial Demotic Greek instead of the old-fashioned Katharevousa). Glinos proposed even the use of the Latin alphabet, in the place of Greek, for tonic reasons.
The structure of the school system (extend primary school from 4 to 6 years)
Educational content (less formalism, greater emphasis on science)
Educational methods (updating of courses and materials)
Teacher training
The education of girls
Glinos eventually became Secretary-General of the Ministry of Education in 1917 under prime minister Eleftherios Venizelos and began to introduce the proposed reforms. His efforts were stopped, and his reforms undone when Venizelos lost power in 1920, and Glinos began publishing under the pseudonym "A. Gabriel, teacher". He re-introduced the reforms after he was reinstated when Venizelos regained power in 1922, but dampened again when Theodore Pangalos took power in 1925.
In 1930 he began his active involvement in politics, being elected as an MP with the Communist Party of Greece in the 1936 elections. 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. At the same time, in December 1942, he was elected a member of the Politburo of the KKE, in whose ranks he had been a member since 1935.
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.[3]
