Prince Sabahaddin

Prince Mehmed Sabahaddin (born in Istanbul on 13 February 1879 – died at Neuchâtel, Switzerland, on 30 June 1948) was an Ottoman prince, sociologist and liberal thinker, the son of Seniha Sultan, daughter of Sultan Abdülmecid I, and of Mahmud Celaleddin Pasha. ^{1 2} He is counted among the founders of sociology in Turkey, a follower of Frédéric Le Play's school as transmitted by Edmond Demolins. ¹

Sabahaddin received a versatile Western education at the palace, showed great interest in the natural sciences and learned French well. ¹ In late 1899 he fled the empire with his father and his brother Ahmed Lutfullah, after his father's fall from Abdul Hamid II's favour, travelling first to Britain and Geneva and then to Paris, where he rose quickly among the Young Turks in exile. ^{1 2}

On 4 February 1902 he convened the First Congress of Ottoman Opposition, where the movement's ideological split showed in full: Sabahaddin proposed a decentralised government based on private initiative and local cooperation, while Ahmed Rıza's Committee of Union and Progress defended a centralised constitutional monarchy — a division the sources treat as the origin of Turkey's later centre-right/centre-left paradigm. ¹ In 1906 he founded the League of Private Initiative and Decentralization and published its journal Terakki. ¹ After the 1908 revolution he returned to Istanbul and founded the Liberty Party in opposition to the CUP; the party was accused over the 31 March Incident and shuttered, and Sabahaddin was arrested and then released through mediation. ¹ After his supporters assassinated Mahmud Shevket Pasha on 11 June 1913 he fled abroad again; he returned to Istanbul in 1919, was exiled in 1924 under the law expelling the House of Osman, and died at Neuchâtel on 30 June 1948. ^{1 2} His body was brought to Turkey in 1952 and buried at Eyüp in Istanbul beside his father and grandfather. ¹

His books include Türkiye Nasıl Kurtarılabilir? ("How Can Turkey Be Saved?", published on his 1919 return after being banned under the CUP), two "Explanations" of private initiative and decentralization, the Open Letters to the Committee of Union and Progress, and a third and final "Explanation" of his doctrine. ¹

Sabahaddin set administrative decentralization and free enterprise against the CUP's centralising national economy, and his worldview is considered the basis of Turkish centre-right politics. ¹ John G. Bennett, who met him in Istanbul in 1920, wrote in his autobiography Witness that in his later years, through frustration, disappointment and exile, Sabahaddin reportedly became an alcoholic and died in great poverty — a contemporary's testimony, recorded here as such. ¹

On his school — the most delicate question in this record: the English article's infobox religion field reads "Sunni Islam", uncited and nowhere discussed in the article's text. ¹ The Arabic article's religion field is empty, the Turkish article has none, and Wikidata gives only the generic item Islam. ^{3 2 4} Since the lane rule records a school only when two independent sources name it as the man's own, and leaves doubt unclassified, his faith is recorded as unknown, with the reading preserved in the record's faith note for any future sourced enrichment. ¹
