The Hellenic National Defence General Staff (Greek: Γενικό Επιτελείο Εθνικής Άμυνας, abbr. ΓΕΕΘΑ) is the senior staff of the Hellenic Armed Forces. It was established in 1950, when the separate armed services ministries were consolidated into the Ministry of National Defence. Its role in peacetime was as a coordinating and senior consultative body at the disposal of the Greek government, and in wartime as the overall headquarters of the Armed Forces. In recent years, through ongoing efforts at increased inter-services cooperation and integration, the HNDGS has assumed peacetime operational control over the separate branches. Between 19 December 1968 and 10 August 1977, the HNDGS was abolished, and the Armed Forces Headquarters (Greek: Αρχηγείο Ενόπλων Δυνάμεων, abbr. Greek: ΑΕΔ) established in its place.
