In the 6th and the 7th government, he served as the Ministrer of National Education between 27 September 1930 and 19 September 1932.^[2][3] Being a former teacher of Mustafa Kemal Pasha, he was one of the most prestigious members of the cabinet. However, he was a conservative minister, and was severely criticized by Reşit Galip, one of the revolutionists of the party. Finally, Esat Sagay resigned from his post in the ministry, and was replaced by Reşit Galip. His memoirs were later published .^[4] In his memoirs, he claims that he was instrumental in Reşit Galip's appointment as his successor.
