The term Caucasian as a racial label for Europeans derives in part from the assumption that the tribe of Japheth developed its distinctive racial characteristics in the Caucasus area, having migrated there from Mount Ararat before populating Europe. In the same vein, Georgian nationalist histories associated Japheth's sons with certain ancient tribes of the Caucasus area, called Tubals (Tabals, Tibarenoi in Greek) and Meshechs (Meshekhs/Mosokhs, Moschoi in Greek), who they claimed represented ancient pre-Indo-European and non-Semitic, possibly Proto-Iberian, tribes of Asia Minor of the 3rd-1st millennia BC. This theory influenced the use of the term Japhetic in the linguistic theories of Nikolai Marr (see below).
