''Turkish State, Turkish Society''. New York: Routledge, 1990.</ref> by the [[Treaty of Constantinople (1913)]] and later confirmed<ref name="Finkel, Andrew 1990" /> by the [[Treaty of Lausanne]] in 1923.

With the exception of [[Mosul]], [[Turkey]] ceded the territories of the present-day [[Iraq]] and [[Syria]] with the [[Treaty of Lausanne]] in 1923. In 1926, [[Turkey]] ceded [[Mosul]] to the [[United Kingdom]] in exchange for 10% the oil revenues from [[Mosul]] for 25 years.<ref name="Shaw, Stanford J. 1976" /> [[Syria]] does (as of 1990) not recognize its [[Syria–Turkey border|border with Turkey]] because of a dispute of the 1939 transfer of [[Hatay Province]] following a referendum that favored union with [[Turkey]].<ref name="Finkel, Andrew 1990" />
