Neokosmos Grigoriadis was born in 1879 in
Constantinople,
Ottoman Empire (today Istanbul,
Turkey) to a
Greek family. He initially graduated from the
Hellenic Army's NCO Academy but eventually he became a regular commissioned officer, and by the end of his military career he had achieved the rank of
Major General. Grigoriadis had an eventful military career. From 1907 to 1909 he was posted in
Vodena (then still part of the Ottoman Empire) as a secret agent working against Turkish and Bulgarian interests during the
Macedonian Struggle; officially, he was principal of Vodena's Greek primary school. He took part in the revolutionary
Goudi Coup in 1909, fought in the
Balkan Wars and
World War I, and sided with the
Venizelists during the
National Schism. In 1920, after the royalist
electoral victory, he was discharged from the Army, but he was recommissioned in 1922 by the
11 September 1922 Revolution, and participated in the
Trial of the Six as "revolutionary commissioner" (public prosecutor). In 1926 he was promoted to Major General, and later that year left the Army for good. Grigoriadis was then involved in politics, being elected
senator for Edessa (renamed from Vodena) for Venizelos's
Liberal Party (1929-1935). However, during the late 1930s he increasingly sympathized with the Left. After the
German invasion of Greece and the Nazi occupation, Grigoriadis was an active member of the left-wing
National Liberation Front (EAM), culminating in his role as Chairman of the "
National Council" that EAM created in 1944 in order to supervise the drafting of a new constitution for post-liberation Greece. Neokosmos Grigoriadis died in 1967. His son,
Solon Grigoriadis (1912–1994), was a respected military writer, historian and journalist. == References ==
