Kılıçzâde İsmail Hakkı (İsmail Hakkı Kılıçoğlu), who were westernist thinkers, took their inspiration rather from the subsequent marginalization of religion in European societies. To them, a reformed religion had only a temporary role to play as an instrument for the modernization of society, after which it would be cast aside (from public life and limited to personal life). Westernization The Young Turks and other Ottoman intellectuals asked the question of the position of the empire regarding the West (primarily taken to mean Christian Europe). The West represented intellectual and scientific ascendancy, and provided the blueprint for the ideal society of the future. Political reforms Republicanism Until the proclamation of the republic, the Ottoman Empire was still in existence, with its heritage of religious and dynastic authority. The Ottoman monarchy was abolished by the Ankara Government, but its traditions and cultural symbols remained active among the people (though less so among the elite). On 1 November 1922, the Ottoman Sultanate was abolished by the Turkish Grand National Assembly and Sultan Mehmed VI departed the country. This allowed the Turkish nationalist government in Ankara to become the sole governing entity in the nation.

The Turkish Constitution of 1921 was the fundamental law of Turkey for a brief period. It was ratified by the Grand National Assembly of Turkey in the middle of the Turkish War of Independence. It was a simple document consisting of only 23 short articles. The major driving force behind the preparation of the 1921 Constitution was that its sovereignty derived from the nation and not from the Sultan, the absolute monarch of the Ottoman Empire. The 1921 Constitution also served as the legal basis for the Turkish War of Independence during 1919–1923, since it refuted the principles of the Treaty of Sèvres of 1918 signed by the Ottoman Empire, by which a great majority of the Empire's territory would have to be ceded to the Entente powers that had won the First World War. In October 1923 the constitution was amended to declare Turkey to be a republic. In April 1924, the constitution was replaced by an entirely new document, the Turkish Constitution of 1924.
