The Kingdom of Diauehi (Georgian: დიაოხის სამეფო) (Diauhi or Diaokhi; "the Land of the Sons of Diau") (Georgian: დიაოხი) was an ancient monarchy emerged as a tribal union of early-Georgians in 12th century BC, in the post-Hittite period. It was located in northeastern Anatolia, mentioned in the Urartian inscriptions. It is usually (though not always) identified with Daiaeni of the Yonjalu inscription of the Assyrian king Tiglath-Pileser I’s third year (1118 BC). Although the exact geographic extent of Diauehi is still unclear, many scholars place it in the Pasinler Plain in today’s northeastern Turkey, while others locate it in the Turkish-Georgian marshlands as it follows the Kura River. Most probably, the core of the Diauehi lands may have extended from the headwaters of the Euphrates into the river valleys of Çoruh to Oltu. The Urartian sources speak of Diauehi’s three key cities – Zua, Utu and Sasilu; Zua is frequently identified with Zivin Kale and Ultu is probably modern Oltu, while Sasilu is sometimes linked to the early medieval Georgian toponym Sasire, near Tortomi (present-day Tortum, Turkey).

The Georgians (Georgian: ქართველები, kartvelebi) are Caucasian ethnic group that have originated in Georgia, where they constitute a majority of the population. Large Georgian communities are also present throughout Russia, European Union, United States, and South America.

The majority of Georgians are Eastern Orthodox Christian and largely adhere to the national autocephalous Georgian Orthodox Church, which originated in the 4th century. There are also Georgian Catholic and Muslim communities in Tbilisi and Adjara.

The Georgian people went through a complex process of nation-formation and currently comprise a diverse set of geographic subgroups, each with its characteristic traditions, manners, dialect and, in the case of Mingrelians and Svans, language. The Georgian language, with its own alphabet and long written tradition going back to the 5th century, is the language of literacy and education of all Georgians living in Georgia as well as the official language of the country. Georgian, Mingrelian and Svan, together with Laz spoken by the related Laz people form the Kartvelian language family.

The Laz (Lazi (ლაზი) or Lazepe (ლაზეფე) in Laz; Lazlar in Turkish; Lazi (ლაზი) or Č’ani (ჭანი) in Georgian) are an ethnic group native to the Black Sea coastal regions of Turkey and Georgia. One of the chief tribes of ancient kingdom of Colchis, the Laz were initially early adopters of Christianity, and most of them subsequently converted to Sunni Islam during Ottoman rule of Caucasus in the 16th century.

The Laz of Turkey form two principal groups. One of these is indigenous to the eastern Black Sea province formerly known as Lazistan (modern Rize and Artvin provinces). The other group fled the Russian expansion later in the 19th century and settled in Adapazarı, Sapanca, Yalova and Bursa, in western and eastern parts of the Black Sea and Marmara regions, respectively. The Laz speak the Laz language, related to Mingrelian, Georgian and Svan (Kartvelian languages). Laz identity in Georgia has largely merged with a Georgian identity and the meaning of "Laz" is seen as merely a regional category, and are mainly concentrated in Ajaria.
