Classical antiquity

During classical antiquity, Albania was home to several Illyrian tribes such as the Albanoi, Ardiaei, Bylliones, Dassaretii, Enchele, Labeatae, Taulantii, Parthini, Penestae, Amantes, and many others, but also Bryges and Epirote tribes, as well as several Greek colonies established on the Illyrian coast in cooperation with the local Illyrians, notably Epidamnos-Dyrrhachium and Apollonia.

The Enchele's polity was the earliest to emerge and centered in Albania. Also the earliest known Illyrian king, Bardylis, emerged in what is now Albania around 400 BC, aiming to make Illyria a regional power interfering with Macedon. He united many southern Illyrian tribes under his realm and defeated the Macedonians and Molossians several times, expanding his dominion over Upper Macedonia and Lynkestis. Before the Rise of Macedon Illyrians were the dominant power in the region. The kingdom of the Taulantii under Glaukias' rule was based in central Albania and dominated southern Illyrian affairs in the late 4th century BC, exerting great influence on the Epirote state through the close ties with the Molossian king Pyrrhus. Under the Ardiaei the greatest known Illyrian kingdom emerged in the 3rd century BC encompassing also northern Albania in its core territory. It became a formidable power both on land and sea by assembling a great army and fleet, and directly ruling over a large area made up of different Illyrian tribes and cities that stretched from the Neretva River in the north to the borders of Epirus in the south, while its influence extended throughout Epirus and down into Acarnania. The dominant power of the Illyrian kingdom in the region ceased after the Illyrian defeat in the Illyro-Roman Wars (229–168 BC). The last known "King of the Illyrians" was Gentius, of the Labeatae tribe.

The Odrysian kingdom (/oʊˈdrɪʒən/; Ancient Greek: Βασίλειον Ὀδρυσῶν), also known as Odrysia, was an ancient Thracian state that thrived between the early 5th century BC and the early 3rd / late 1st century BC. Located in present-day Bulgaria, southeastern Romania (Northern Dobruja), northern Greece and European Turkey, it was a tribal amalgam dominated by the Odrysians that was the first large political entity to develop in the eastern Balkans.

The Odrysian kingdom was founded by king Teres I, who was exploiting the collapse of the Persian presence in Europe due to the failed invasion of Greece in 480–79. Teres and his son Sitalces pursued a policy of expansion, making the kingdom one of the most powerful of its time. Throughout much of its early history it remained an ally of Athens and even joined the Peloponnesian War on its side. By 400 BC the state showed first signs of fatigue, although the skilled Cotys I initiated a brief renaissance that lasted until his murder in 360 BC.

The Pontic–Caspian Steppe is a steppe extending across Eastern Europe to Central Asia, formed by the Caspian and Pontic steppes. It stretches from the northern shores of the Black Sea (the Pontus Euxinus of antiquity) to the northern area around the Caspian Sea, where it ends at the Ural-Caspian narrowing, which joins it with the Kazakh Steppe in Central Asia, making it a part of the larger Eurasian Steppe. Geopolitically, the Pontic–Caspian Steppe extends from northeastern Bulgaria and southeastern Romania through Moldova, southern and eastern Ukraine, through the North Caucasus of southern Russia, and into the Lower Volga region where it straddles the border of southern Russia and western Kazakhstan. Biogeographically, it is a part of the Palearctic realm, and of the temperate grasslands, savannas, and shrublands biome.

The area corresponds to Cimmeria, Scythia, and Sarmatia of classical antiquity. Across several millennia, numerous tribes of nomadic horsemen used the steppe; many of them went on to conquer lands in the settled regions of Central and Eastern Europe, West Asia, and South Asia.

The various names used since classical times for the people known today as the Celts are of disparate origins.

The names Κελτοί (Keltoí) and Celtae are used in Greek and Latin, respectively, to denote a people of the La Tène horizon in the region of the upper Rhine and Danube during the 6th to 1st centuries BC in Graeco-Roman ethnography. The etymology of this name and that of the Gauls Γαλάται Galátai / Galli is uncertain.

The Eurasian Steppe, also called the Great Steppe or The Steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas and shrublands biome. It stretches through Manchuria, Mongolia, Xinjiang, Kazakhstan, Siberia, European Russia, Ukraine, Moldova, Romania, Bulgaria, Hungary and Slovakia.

Since the Paleolithic age, the Steppe Route has been the main overland route between Eastern Europe, North Asia, Central Asia and East Asia economically, politically, and culturally. The Steppe route is a predecessor not only of the Silk Road, which developed during antiquity and the Middle Ages, but also of the Eurasian Land Bridge in the modern era. It has been home to nomadic empires and many large tribal confederations and ancient states throughout history, such as the Xiongnu, Scythia, Cimmeria, Sarmatia, Hunnic Empire, Sogdia, Xianbei, Mongol Empire, Magyar tribes, and Göktürk Khaganate.

Nomadic empires, sometimes also called steppe empires, Central or Inner Asian empires, were the empires erected by the bow-wielding, horse-riding, nomadic people in the Eurasian Steppe, from classical antiquity (Scythia) to the early modern era (Dzungars). They are the most prominent example of non-sedentary polities.

Some nomadic empires consolidated by establishing a capital city inside a conquered sedentary state and then exploiting the existing bureaucrats and commercial resources of that non-nomadic society. In such a scenario, the originally nomadic dynasty may become culturally assimilated to the culture of the occupied nation before it is ultimately overthrown. Ibn Khaldun (1332–1406) described a similar cycle on a smaller scale in 1377 in his Asabiyyah theory.

Georgians, or Kartvelians (/kɑːrtˈvɛliənz/; Georgian: ქართველები, romanized: kartvelebi, pronounced [kʰaɾtʰʷelebi]), are a nation and Caucasian ethnic group native to present-day Georgia and surrounding areas historically associated with the Georgian kingdoms. Significant Georgian diaspora communities are also present throughout Russia, Turkey, Greece, Iran, Ukraine, the United States, and the European Union.

Georgians arose from Colchian and Iberian civilizations of classical antiquity; Colchis was interconnected with the Hellenic world, whereas Iberia was influenced by the Achaemenid Empire until Alexander the Great conquered it. In the early 4th century, the Georgians became one of the first to embrace Christianity. Currently, the majority of Georgians are Orthodox Christians, with most following their national Georgian Orthodox Church; there are also small Georgian Catholic and Muslim communities as well as a significant number of irreligious Georgians. Located in the Caucasus, on the continental crossroads of Europe and Asia, the High Middle Ages saw Georgian people form a unified Kingdom of Georgia in 1008 AD, later inaugurating the Georgian Golden Age. This lasted until the kingdom was weakened and later disintegrated as the result of the 13th–15th-century invasions of the Mongols and Timur, the Black Death, the Fall of Constantinople, as well as internal divisions following the death of George V the Brilliant in 1346, the last of the great kings of Georgia.

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."

The Christianization of Iberia (Georgian: ქართლის გაქრისტიანება, romanized: kartlis gakrist'ianeba) refers to the spread of Christianity in the early 4th century as a result of the preaching of Saint Nino in the ancient Georgian kingdom of Kartli, known as Iberia in classical antiquity. The then-pagan king of Iberia Mirian III declared Christianity to be the kingdom's state religion. According to Roman historian Sozomen, this led the king's "large and warlike barbarian nation to confess Christ and renounce the religion of their fathers", as the polytheistic Georgians had long-established anthropomorphic idols, known as the "Gods of Kartli". The king would become the main sponsor, architect, initiator and an organizing power of all building processes.

Per Socrates of Constantinople, the "Iberians first embraced the Christian faith" alongside the Abyssinians, present day Ethiopians but the exact date of the event is still debated. The kings of Georgia and Armenia were among the first monarchs anywhere in the world to convert to the Christian faith. Prior to the escalation of the Armeno-Georgian ecclesiastical rivalry and the Christological controversies, their Caucasian Christianity was extraordinarily inclusive, pluralistic and flexible that only saw the rigid ecclesiological hierarchies established much later, particularly as "national" churches crystallised from the 6th century. Despite the tremendous diversity of the region, the Christianization process was a pan-regional and a cross-cultural phenomenon in the Caucasus, Eurasia's most energetic and cosmopolitan zones throughout the late antiquity, hard enough to place Georgians and Armenians unequivocally within any one major civilization.

The unification of the Georgian realm (Georgian: ქართული სახელმწიფოს გაერთიანება, romanized: kartuli sakhelmts'ipos gaertianeba) was the 10th-century political movement that resulted in the consolidation of various Georgian crowns into a single realm with centralized government in 1008, the Kingdom of Georgia, or Sakartvelo. It was originally initiated by the powerful local aristocracy of the eristavs, due to centuries-long power struggles and aggressive wars of succession between the Georgian monarchs, arising from their independent ruling traditions of classical antiquity and their Hellenistic-era monarchical establishments in Colchis and Iberia.

The initiative was supported by David III the Great of the Bagrationi dynasty, the most powerful ruler in the Caucasus at the time, who would put prince royal Bagrat, his kin and foster-son, on the Iberian throne, who would eventually be crowned King of all-Georgia. David's Bagratid successors would become the champions of national unification, just like the Rurikids or the Capetians, but despite their enthusiasm, some of the Georgian polities that had been targeted for unification did not join the unification freely and would actively fight against it throughout this process, mostly seeking help and support from the Byzantine Empire and the Abbasid Caliphate. Even though the 1008 unification of the realm would unite most of western and central Georgian lands, the process would continue to the east, and eventually reach its total completion under King David IV the Builder. This unprecedented political unification of lands and the meteoric rise of Bagrationi power would inaugurate the Georgian Golden Age and creation of the only medieval pan-Caucasian empire, attaining its greatest geographical extent and dominating the entire Caucasus in the 11th, 12th and 13th centuries.
