How did invasions and migration affect the cultures and languages of the Caucasus?

The Caucasus region has long served as a critical gateway for migration between Europe and Asia, functioning as both a crossroads for diverse peoples and an "ethnic museum" where various groups settled in isolated mountain ravines to preserve their distinct identities.12

Impact on Culture and Language

Successive waves of invasions—including Scythians, Huns, Arabs, Seljuq Turks, and Mongols—left deep imprints on the region's cultural landscape. These interactions introduced Middle Eastern influences, such as the spread of Iranian languages and the establishment of Christianity and Islam.32

Linguistically, the region is remarkably diverse, often referred to as the "Mountain of Languages". While many indigenous groups speak Caucasian languages (categorized into Kartvelian, Abkhazo-Adyghian, and Nakho-Dagestanian families), migrations also introduced Indo-European and Turkic languages. For instance, the 11th-century Seljuq invasions significantly altered the local population and led to the linguistic dominance of Oghuz Turkic in parts of the region. Later, from the 16th century onward, the expansion of Russian culture further influenced the demographic and linguistic makeup of the Caucasus.234
