Ioannis Metaxas (born April 12, 1871, Ithaca, Greece—died January 29, 1941, Athens) was a general and statesman who was dictator of Greece from 1936 to 1941.
After active service in the Greco-Turkish war of 1897, Metaxas completed his military training in Germany. He distinguished himself on the Greek general staff during the Balkan Wars (1912–13) and was appointed chief of staff in 1913 and promoted to general in 1916. During World War I he unsuccessfully fought to maintain Greek neutrality and opposed the plans of Prime Minister Eleuthérios Venizélos for the conquest of western Anatolia, accurately predicting the military catastrophe that ultimately overtook the Greek offensive in Anatolia in 1921–22. Strongly monarchist in his politics, he was exiled after the deposition of King Constantine I (1917) but returned after the king’s restoration in 1920. With the fall of the monarchy in 1923, Metaxas again temporarily left Greece, but later he held ministerial office under the republic (1928).
During the following years Metaxas provided formidable opposition to the government at the head of a small ultraroyalist party. Shortly after the monarchy’s restoration in 1935, King George II appointed him minister of army affairs on March 5, 1936, and premier roughly a month later (April 13, 1936). Finally, on August 4, 1936, he inaugurated a dictatorship under royal authorization. His Fourth of August Regime vigorously suppressed political opposition and succeeded in carrying out some beneficial economic and social reforms. When Italy invaded Greece in 1940, Metaxas brought a united country into the Western alliance. He remained in power until his death.
