Example Input: Question: What time period did George II serve as king? Passage:Born to an aristocratic family in Ithaca, Metaxas took part in the Greco-Turkish War of 1897 and the Balkan Wars (191213), quickly rising through the ranks of the Hellenic Army. A royalist during the National Schism, Metaxas unsuccessfully opposed Prime Minister Eleftherios Venizelos and Greece's entry in World War I; as a result, he was exiled to Corsica in 1917. On his return, Metaxas moved into politics and founded the Freethinkers' Party, but had only limited success under the Hellenic Republic. The Greek monarchy was restored in 1935, and Metaxas was appointed Prime Minister in April 1936. On 4 August 1936, with the support of King George II, Metaxas initiated a self-coup and established an authoritarian, nationalist and anti-communist regime.
