Kemalism (Kemalizm, Atatürkçülük) is the founding ideology of the Republic of Turkey, codified after the death of Mustafa Kemal Atatürk in 1938 as the Six Arrows of the Republican People's Party (CHP): republicanism, populism, nationalism, secularism, statism and reformism. Doctrinally it rests on three foundations: a French-Jacobin model of an indivisible territorial nation; a top-down secularism (laiklik) that placed religion under state control; and a Turkish ethnic-civic nationalism whose canonical formula, the Sun Language Theory and the Turkish History Thesis of the 1930s, projected the new nation deep into Anatolian antiquity.

For the Armenian question Kemalism amounted to closure by territorial fait accompli. The 1920 Treaty of Sèvres, which had carved out a "Wilsonian Armenia" reaching to the Black Sea, was rendered void by the Kemalist victory in the Turkish-Armenian war of 1920 (under General Kâzım Karabekir) and superseded by the Treaty of Lausanne (1923), in which the Western powers conceded the eastern frontier and dropped both the territorial and the minority-protection provisions of Sèvres. The genocide was reframed in official memory as wartime "tragedy" affecting all Anatolians, and the surviving non-Muslim minorities were progressively dispossessed (1942 Wealth Tax, 1955 Istanbul pogrom, the 1936 declaration regime). Akçam argues that Kemalism inherited and consolidated the demographic results of the CUP's wartime policies rather than breaking with them.

In its contemporary form, Kemalism is contested between the secular-nationalist establishment (the army, the CHP, the bar associations, parts of the academy) and the post-2002 AKP-led Islamo-conservative bloc, which has dismantled much of the Kemalist legal architecture while retaining its core nationalism. Both traditions converge on non-recognition of the Armenian Genocide (sourced opinion: Göçek traces the continuity of denialist scholarship from the early Republic into the 21st century, identifying official, scholarly, and oppositional layers of denial).
