Pan-Turkism or Turkism is a political movement that emerged during the 1880s among Turkic intellectuals who lived in the Russian region of Kazan (Tatarstan), Caucasus and the Ottoman Empire, with its aim being the cultural and political unification of all Turkic peoples. Turanism is a closely related movement but it is a more general term, because Turkism only applies to Turkic peoples. However, researchers and politicians who are steeped in the pan-Turkic ideology have used these terms interchangeably in many sources and works of literature.

Mehmet Ziya Gökalp was a Turkish sociologist, writer, poet, and politician. After the 1908 Young Turk Revolution that reinstated constitutionalism in the Ottoman Empire, he adopted the pen name Gökalp, which he retained for the rest of his life. As a sociologist, Ziya Gökalp was influential in the negation of Islamism, pan-Islamism, and Ottomanism as ideological, cultural, and sociological identifiers. In a 1936 publication, sociologist Niyazi Berkes described Gökalp as "the real founder of Turkish sociology, since he was not a mere translator or interpreter of foreign sociology".
