Kura (Caspian Sea) in the context of "Rustavi"

The Lesser Caucasus or Lesser Caucasus Mountains, also called Caucasus Minor, is the second of the two main ranges of the Caucasus Mountains, of length about 600 km (370 mi). The western portion of the Lesser Caucasus overlaps and converges with east Turkey and northwest Iran. It runs parallel to the Greater Caucasus, at a distance averaging about 100 km (62 mi) south from the Likhi Range (Georgia), and limits east Turkey from the north and north-east. It is connected with the Pontic range and separated from it by the Kolkhida Lowland (Georgia) in the west and Kura-Aras Lowland (Azerbaijan) (by the Kura River) in the east.

Tbilisi (/təbɪˈliːsi, təˈbɪlɪsi/ tə-bil-EE-see, tə-BIL-iss-ee; Georgian: თბილისი, pronounced [ˈtʰbilisi] ), Georgian: ტფილისი, romanized: t'pilisi [tʼpʰilisi]) is the capital and largest city of Georgia, located on the banks of the Kura River. With more than 1.3 million inhabitants, it contains almost one third of the country's population. Tbilisi was founded in the fifth century AD by Vakhtang I of Iberia and has since served as the capital of various Georgian kingdoms and republics. Between 1801 and 1917, then part of the Russian Empire, it was the seat of the Caucasus Viceroyalty, governing both the northern and the southern sides of the Caucasus.

Because of its location at the crossroads between Europe and Asia, and its proximity to the lucrative Silk Road, throughout history, Tbilisi has been a point of contention among various global powers. To this day, the city's location ensures its position as an important transit route for energy and trade projects. Tbilisi's history is reflected in its architecture, which is a mix of medieval, neoclassical, Beaux Arts, Art Nouveau, Stalinist, and Modern structures.

Europe is traditionally defined as one of seven continents. Physiographically, it is the northwestern peninsula of the larger landmass known as Eurasia (or the larger Afro-Eurasia); Asia occupies the centre and east of this continuous landmass. Europe's eastern frontier is usually delineated by the Ural Mountains in Russia, which is the largest country by land area in the continent. The southeast boundary with Asia is not universally defined, but the modern definition is generally the Ural River or, less commonly, the Emba River. The boundary continues to the Caspian Sea, the crest of the Caucasus Mountains (or, less commonly, the river Kura in the Caucasus), and on to the Black Sea. The Bosporus, the Sea of Marmara, and the Dardanelles conclude the Asian boundary. The Mediterranean Sea to the south separates Europe from Africa. The western boundary is the Atlantic Ocean. Iceland is usually included in Europe because it is over twice as close to mainland Europe as mainland North America. There is ongoing debate on where the geographical centre of Europe falls.

The Kingdom of the Iberians (Georgian: ქართველთა სამეფო, romanized: kartvelta samepo) was a medieval Georgian monarchy under the Bagrationi dynasty which emerged circa 888 AD, succeeding the Principality of Iberia, in historical region of Tao-Klarjeti, or upper Iberia in north-eastern Turkey as well parts of modern southwestern Georgia, that stretched from the Iberian gates in the south and to the Lesser Caucasus in the north.

Historically, the area comprised the following historical districts: West of the Arsiani Mountains were Tao, Klarjeti, Nigali, and Shavsheti, to the east lay Meskheti, Erusheti, Javakheti, Artaani, Abotsi, Kola and Basiani. The landscape is characterised by mountains and the river-systems of the Çoruh and the Kura. The region played a crucial role in the unification of all Georgian lands and principalities into the Kingdom of Georgia in 1008.

Utik (Armenian: Ուտիք, romanized: Utik’), also known as Uti, was a historical province and principality within the Kingdom of Armenia. It was ceded to Caucasian Albania following the partition of Armenia between Sassanid Persia and the Eastern Roman Empire in 387 AD. Most of the region is located within present-day Azerbaijan immediately west of the Kura River, while a part of it lies within the Tavush province of present-day northeastern Armenia.

The Shaddadids were a Sunni Muslim dynasty of Kurdish origin. who ruled in various parts of Armenia and Arran from 951 to 1199 AD. They were established in Dvin. Through their long tenure in Armenia, they often intermarried with the Bagratuni royal family of Armenia.

They began ruling in the city of Dvin, and eventually ruled other major cities, such as Barda and Ganja. A cadet line of the Shaddadids were given the cities of Ani and Tbilisi as a reward for their service to the Seljuqs, to whom they became vassals. From 1047 to 1057, the Shaddadids were engaged in several wars against the Byzantine army. The area between the rivers Kura and Aras was ruled by a Shaddadid dynasty.

Tao-Klarjeti (Georgian: ტაო-კლარჯეთი, romanized: t'ao-k'larjeti [tʼäo̞kʼɫäɾd͡ʒe̞t̪ʰi]) is a Georgian historical and cultural region in north-eastern Turkey. The region is based around two river basins - Chorokhi and Kura (Mtkvari), and also partially includes the upper source of the Aras river. In modern usage it most often denotes the territory that was administered or claimed by Georgian Democratic Republic but is nowadays part of Turkey due to the Soviet-Turkish deal in 1921.

The term "Tao-Klarjeti" is based on the names of two most important provinces of the region — Tao and Klarjeti. The term is equivalent to “Zemo Kartli” (i.e., Upper Kartli or Upper Iberia) and is also a synonym for historical Meskheti.

Zemo Kartli (Georgian: ზემო ქართლი; lit. Upper Kartli or Upper Iberia) is a historical region in south-western Georgia, comprising the lands in the upper basin of the Kura River (from origins of Kura River to Tashiskari) and Chorokhi River basin, making it subregion of greater Kartli. Until 16th century, Zemo Kartli included: Samtskhe, Javakheti, Erusheti, Artaani, Kola, Klarjeti, Shavsheti, Tao and Speri.
