The Six Arrows (Turkish: Altı Ok) is the symbol and flag of the Turkish Republican People's Party (CHP). The arrows represent the fundamental pillars of Kemalism, Turkey's founding ideology.[1] These are Republicanism, Folkism, Nationalism, Laicism, Statism, and Reformism.[2] The arrows are believed to have been conceived by İsmail Hakkı Tonguç,[3] a Turkish scientist who made significant contributions to the Turkish education system.[4] The principles of the Six Arrows were added to the Turkish Constitution on 5 February 1937. From August 1938 the flag was hoisted at all official buildings.[5]
