Ptolemaios Sarigiannis

Ptolemaios Sarigiannis (, 1882–1958) was a Greek Army officer who rose to the rank of Major General, holding senior staff positions during the Greco-Turkish War of 1919–1922 and serving as Chief of the Hellenic Army General Staff in 1925–1926.

Life Ptolemaios Sarigiannis was born in Piraeus in about 1882. He entered the Hellenic Army Academy in 1900 and was commissioned a 2nd Lieutenant of Engineers on 9 July 1903. He later completed his studies as a staff officer in the École Supérieure de Guerre.

Promoted to Captain in 1913 and Major in 1915, Sarigiannis joined the Venizelist Movement of National Defence, and served as chief of staff of the Crete Division on the Macedonian front. Promoted to Lt. Colonel in 1917, he was again promoted to Colonel in 1919 in recognition of distinguished service during the May 1918 Battle of Skra-di-Legen.

Sarigiannis played a crucial role in the Greco-Turkish War of 1919–1922, initially as chief of staff to the Army of Occupation in the Smyrna Zone, as deputy chief of staff to the expanded Army of Asia Minor during the 1921 operations, and finally as deputy chief of staff in the Army of Thrace. In this capacity he also participated in the February 1921 London Conference as a member of the Greek delegation under Prime Minister Nikolaos Kalogeropoulos. Following the collapse of the Greek front in August 1922, he participated in the Greek delegation to the Mudanya Armistice negotiations under Major General Alexandros Mazarakis-Ainian.

Sarigiannis was dismissed from the army shortly after, but was recalled to active service, promoted Major General and placed as head of the Hellenic Army General Staff (replacing Mazarakis-Ainian) in 1925, when general Theodoros Pangalos seized power. Sarigiannis was dismissed again on 31 August 1926, after Pangalos' fall, and was replaced by Mazarakis-Ainian.

In 1944, after Greece was liberated from German occupation, he served briefly as Vice-Minister of Military Affairs. Prior to that, he was elected as a member of the National Council established by the National Liberation Front.

He died in 1958.
