What treaty signed by the Central Powers signed after their defeat in World War I did Rıza Tevfik Bölükbaşı sign?
Rıza Tevfik Bölükbaşı 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.
Kingdom of Bulgaria The Kingdom of Bulgaria (Bulgarian: Царство България , "Tsarstvo Bǎlgariya"), also referred to as the Tsardom of Bulgaria and the Third Bulgarian Tsardom, was a constitutional monarchy, which was established on 5 October (O.S. 22 September) 1908 when the Bulgarian state was raised from a principality to a kingdom. Ferdinand I was crowned a Tsar at the Declaration of Independence, mainly because of his military plans and for seeking options for unification of all Balkan lands with an ethnic Bulgarian majority (lands that had been seized from Bulgaria and given to the Ottoman Empire in the Treaty of Berlin).
