Emmanouil or Manolis Mantakas (Greek: Μανώλης Μάντακας, Lakkoi 1891 - Athens 1968) was a Greek Army officer who rose to the rank of Major General, and who became a leader in the Greek Resistance and a politician.
He was born in Lakkoi in 1891 and joined the Hellenic Army in 1910. He fought in the Balkan Wars and took part in the Movement of National Defence. He studied as a staff officer in the École Supérieure de Guerre and fought in the Asia Minor Campaign. A staunch republican, he was dismissed from the Army after the royalist coup of 1 October 1935, and took part in the abortive 1938 uprising in Chania against the dictatorial Metaxas Regime. During World War II he became a leader in the Cretan Resistance and joined the Communist-controlled National Liberation Front and the Greek People's Liberation Army resistance groups. He also served in the EAM-organized government of "Free Greece", the Political Committee of National Liberation, as Secretary for Military Affairs and later as its Vice-President, and was elected a deputy for Piraeus Prefecture in the PEEA's parliament, the "National Council".
