Colchis

In classical antiquity and Greco-Roman geography, Colchis (/ˈkɒlkɪs/; Ancient Greek: Κολχίς) was an exonym for the Georgian polity of Egrisi (Georgian: ეგრისი) located on the eastern coast of the Black Sea, centered in present-day western Georgia also including the region of Abkhazia.

Its population, the Colchians, are generally believed to have been primarily early Zan-speaking tribes, ancestral to the modern Laz and Mingrelian peoples. According to David Marshall Lang: "one of the most important elements in the modern Georgian nation, the Colchians were probably established in the Caucasus by the Middle Bronze Age."

It has been described in modern scholarship as "the earliest Georgian formation", which, along with the Kingdom of Iberia, would later contribute significantly to the development of the Kingdom of Georgia and the Georgian nation.

Colchis is known in Greek mythology as the destination of the Argonauts, as well as the home to Medea and the Golden Fleece. It was also described as a land rich with gold, iron, timber and honey that would export its resources mostly to ancient Hellenic city-states. Colchis likely had a diverse population. According to Greek and Roman sources, between 70 and 300 languages were spoken in Dioscourias (modern Sukhumi) alone.

Colchis territory is mostly assigned to what is now the western part of Georgia and encompasses the present-day Georgian provinces of Samegrelo, Imereti, Guria, Adjara, Svaneti, Racha; Abkhazia; modern Russia's Sochi and Tuapse districts; and present-day Turkey’s Artvin, Rize, and Trabzon provinces.
