Rıza Tevfik (Rıza Tevfik Bölükbaşı after the Surname Law of 1934; 1869 – 31 December 1949) was a Turkish philosopher, poet, politician, and a community leader (for some members among the Bektashi community) of late 19th century and early 20th century. A polyglot, he is most remembered in Turkey for being one of the four Ottoman signatories of the disastrous Treaty of Sèvres, for which reason he was included in 1923 among the 150 personae non gratae of Turkey, and he spent 20 years in exile until he was given amnesty by Turkey in 1943.
Rıza Tevfik was born in 1869 in Mustafapaşa, today Svilengrad in Bulgaria. He had a brother, Besim, who would later commit suicide in Edirne. Placed in a Jewish school in Istanbul by his father, who was a prefect, Rıza Tevfik learned Spanish and French at an early age. He was remarked as a restless personality during his student years, first in the famed Galatasaray High School, and then in the Imperial School of Medicine (Tıbbiye), and he was arrested and incarcerated several times, not falling short of inciting fellow inmates to revolt during his prison months. He could graduate at the age thirty and became a doctor. In 1907, he joined the Committee of Union and Progress (CUP), and was one of that party's deputies for Edirne in the Chamber of Deputies (the popularly elected lower house of the re-established Ottoman Parliament) of 1908. He split with the CUP in 1911, joining for a short while the newly founded opposition Freedom and Accord Party (Liberal Entente), and was vehemently opposed to its entry of the Ottoman Empire into World War I.
