Sun Language Theory
Turkish nationalist pseudoscientific theory

The Sun Language Theory (Turkish: Güneş Dil Teorisi) was a Turkish pseudolinguistic, pseudoscientific quasi-hypothesis developed in Turkey in the 1930s that proposed that all human languages are descendants of one proto-Turkic primal language. The theory's promotion of Turks as a progenitor race led to it finding favour among Turkish ultranationalists, who used it to justify their nationalist ideology.
It claims that primal language had close phonemic resemblances to Turkish and, because of this, all other languages can be traced back to Turkic roots. According to the theory, this primal language originated among Central Asian worshippers who created it as a means to salute the omnipotence of the sun and its life-giving qualities, hence the name.
Origins
Influences on the theory included:
the ideas of the French historian Hilaire de Barenton, expressed in "L'Origine des Langues, des Religions et des Peuples" ("The Origin of Languages, Religions and Peoples"), that all languages originated from hieroglyphs and cuneiform used by Sumerians. Turkish linguists claimed a Turkish origin for the Sumerians, and therefore the origin of language was Turkish.
a paper of the Austrian linguist Hermann F. Kvergić of Vienna entitled "La psychologie de quelques éléments des langues Turques" ("The Psychology of Some Elements of the Turkic Languages"). He also conducted some research on the theory with support of the Turkish Embassy in Vienna.
During ten months in late 1935 and early 1936 Turkish linguists from the Turkish Language Society developed the Sun Language Theory which was presented as the source of all languages in the Third Turkish Language Congress.
History
The theory counted on the approval of the first president of the Republic of Turkey, Mustafa Kemal Atatürk, who not only gave the theory official backing and material support but was also an important contributor to its development.

Why this record matters
The phrase “turkish nationalist pseudoscientific theory” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 2, 2026. The linked authority identifier is Q1193977. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1935 and 1936.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
