Information:  - The Caucasus or Caucasia is a region at the border of Europe and Asia, situated between the Black and the Caspian seas.  - Historical regions (or historical countries) are delimitations of geographic areas for studying and analysing social development of period-specific cultures without any reference to contemporary political, economic or social organisations. The fundamental principle underlying this view is that older political and mental structures exist which exercise greater influence on the spatial-social identity of individuals than is understood by the contemporary world, bound to and often blinded by its own worldview - e.g. the focus on the nation-state. Definitions of regions vary, and regions can include macroregions such as Europe, territories of traditional states, or smaller microregional areas. A geographic proximity is the often required precondition for emergence of a regional identity. In Europe the regional identities are often derived from the Migration Period, but for the contemporary perspective are related to the 1918-1920 time of territorial transformation, and another in the post-Cold War period.  - Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets.  - Classical Armenian ("grabar", Western Armenian "krapar", meaning "literary [language]"; also Old Armenian or Liturgical Armenian) is the oldest attested form of the Armenian language.

Until the early 20th century, various Western Armenian dialects were spoken in the Ottoman Empire, especially in the eastern regions historically populated by Armenians known as Western Armenia. Following the extermination of the Armenian population during the Armenian Genocide of 1915 Western Armenian is now spoken, almost exclusively, in the Armenian diaspora communities around the world. As a diasporic language, and as a language that is not an official language of any state, Western Armenian faces extinction as its native speakers lose fluency in Western Armenian amid pressures to assimilate into their host countries. Estimates place the number of fluent speakers of Western Armenian at less than one million.  - Albania (Latin: ', Greek: , in Old Armenian:  "Auank" ("Aguank"), Parthian: "Ardhan", Middle Persian: "Arran"); usually referred to as Caucasian Albania"' for disambiguation with the modern state of Albania (the native name for the country is unknown), is a name for the historical region of the eastern Caucasus, that existed on the territory of present-day republic of Azerbaijan (where both of its capitals were located) and partially southern Dagestan.
