Kemalist historiography (Turkish: Kemalist tarihyazımı) is a narrative of history mainly based on a six-day speech delivered by Mustafa Kemal [Atatürk] in 1927, promoted by the political ideology of Kemalism, and influenced by Atatürk's cult of personality. It asserts that the Republic of Turkey represented a clean break with the Ottoman Empire, and that the Republican People's Party did not succeed the Committee of Union and Progress (CUP). These claims have been widely rejected by scholars, notably by Taner Akçam, Erik-Jan Zürcher, Uğur Ümit Üngör and Hans-Lukas Kieser.
