Over 90% of Albania's people are ethnic Albanian, and Albanian is the official language. Religions include Muslim (Sunni and Bektashi), Albanian Orthodox, and Roman Catholic.Scholars believe the Albanian people are descended from a non-Slavic, non-Turkic group of tribes known as Illyrians, who arrived in the Balkans around 2000 BC. Modern Albanians still distinguish between Ghegs (northern tribes) and Tosks (southern tribes). After falling under Roman authority in 165 BC, Albania was controlled nearly continuously by a succession of foreign powers until the mid-20th century, with only brief periods of self-rule.

Following the split of the Roman Empire in 395, the Byzantine Empire established its control over present-day Albania. In the 11th century, Byzantine Emperor Alexius I Comnenus made the first recorded reference to a distinct area of land known as Albania and to its people.
