Panticapeum (modern Kerch), the major city of the Kingdom of the Bosporus situated on Kerch Strait in present-day southern Ukraine, comes under the rule of the Greek Archaeanactid dynasty in 480 BCE.

During the first centuries of the city's existence, imported Greek articles predominate: pottery, terra cotta works, and metal objects, probably from workshops in Rhodes, Corinth, Samos, and Athens.

Local production, imitated from the models, is carried on at the same time.

Athens manufactures a special type of bowl for the city, known as Kerch ware.

Local potters imitate the Hellenistic bowls known as the Gnathia style as well as relief wares—Megarian bowls.

The city mints silver coins from the mid-sixth century BCE.

The Spartocid dynasty replaces that of the Archeanactids in the Bosporan Kingdom in 438 BCE, annexing to Panticapaeum other Greek colonies—e.g., Nymphaeum, which had been founded in the region in the seventh and sixth centuries.

Athenian influence has been strong among the Bosporus cities after the second half of the fifth century; Athens controls local trade until 404 BCE and will remain the chief customer of the Bosporus' food and other exports throughout the fourth century.

Satyrus I (r. 433 BC - 389 BCE) and the other Spartocid rulers of the Bosporus kingdom had been honored by awards of Athenian citizenship because they had promised to provide Athens with wheat, as their predecessor Leucon had done before them in the mid-fifth century.

These rulers (as inscriptions show) call themselves archon when dealing with their Greek subjects but king when describing their authority over the native population.

Leukon, ruler of the Bosporan Kingdom from 387 BCE, is noted in antiquity as a strategist and a disciplinarian.

In the writings of Aeneas Tacticus, How to Survive under Siege, he dismissed his guards who owed gambling debts, because their loyalty could be doubted during a city siege.

He continues the war of his father against Theodosia and Chersonesus with the goal of annexing all the Greek colonies in the Bosporus.

He also makes Sindike his vassal, and in an inscription from Nymphaion he is described as "archon of the Bosporus, Theodosia, all Sindike".

Chersonesus (Heracleotic Chersonese), prosperous from the fourth century BCE through trade with Athens and cities on the Pontic coast, maintains a free constitution of the Greek type.

The city-state fights for its continued independence against the Scythians of southern Russia, against the native Tauri of the southern Crimea, and against the Bosporan kingdom in the west.

Theodosia (modern Feodosiya) is situated on the southern coast of the Crimean Peninsula on the western shores of Feodosiya Bay.

Originally called Ardabda by its natives, terra cottas show it to have been inhabited in the sixth century BCE, but it is first heard of in history as resisting the attacks of Satyrus, ruler of the Bosporan kingdom, or Cimmerian Bosporus, about 390 BCE.

His successor Leukon, who succeeds to the throne in 387 BCE, transforms it into a great port for shipping wheat to Greece, especially to Athens.

East Europe (333–190 BCE): Scythian Decline and the Rise of Sarmatians

Political and Military Developments

Decline of Scythian Dominance

Between 333 and 190 BCE, the Scythian influence, dominant in previous centuries, began to decline due to internal divisions, external pressures, and intensified competition with rising tribal powers. Increasingly fragmented, their territories shrank significantly, confined primarily to regions closer to the Crimean Peninsula.

Ascendancy of the Sarmatians

The period saw the rise of the Sarmatians, Iranian-speaking nomadic tribes from Central Asia who expanded westward into the Pontic–Caspian steppe. Their martial prowess and organizational strength gradually displaced the Scythians, and they became the new dominant nomadic force in the region.

Economic and Technological Developments

Transition in Trade Networks

As Scythian control weakened, trade networks experienced shifts in influence. The Sarmatians capitalized on existing trade routes, maintaining connections with Greek colonies and further eastward, reinforcing their economic strength through continued exchanges of metals, textiles, and luxury goods.

Advancements in Cavalry and Warfare

The Sarmatians introduced advanced cavalry tactics and weaponry innovations, notably their heavy armored cavalry. Their enhanced military technology became influential in shaping subsequent warfare practices throughout Eurasia.

Cultural and Artistic Developments

Emergence of Sarmatian Artistic Styles

Building upon the established Scythian artistic legacy, the Sarmatians developed their distinctive style characterized by intricate designs in metalwork and jewelry, featuring animal motifs alongside symbolic elements that reflected their Central Asian origins.

Continuity and Change in Greek Cultural Influence

Cultural interactions with Greek colonies continued, with sustained exchanges influencing Sarmatian art and material culture. The hybridization of Greek and Iranian artistic traditions was evident, particularly in elite Sarmatian burial sites.

Settlement Patterns and Urban Development

Expansion of Permanent Settlements

The decline of nomadic dominance prompted increased stability and the further establishment of fortified settlements and semi-urban communities, particularly along key trade routes and near strategic locations such as river crossings and resource-rich areas.

Influence of Zarubintsy and Przeworsk Cultures

The archaeological presence of the Zarubintsy and early Przeworsk cultures grew significantly during this period. Their settlements and distinctive ceramic styles marked a notable cultural development in northern regions, highlighting an increased sedentary lifestyle.

Social and Religious Developments

Evolution of Social Structures

Sarmatian society was structured similarly to that of their Scythian predecessors, with warrior elites displaying wealth and power through elaborate burials, rich grave goods, and extensive use of ornate weaponry. Tribal leadership and hierarchical structures became more pronounced.

Religious Practices and Syncretism

Religious traditions continued to center around shamanistic practices, ancestor worship, and animal symbolism, with additional influences from Greek and Eastern Iranian traditions. These syncretic practices were reflected in burial customs and religious artifacts.

Long-Term Consequences and Historical Significance

The era from 333 to 190 BCE marked a transitional phase in East Europe’s historical landscape, characterized by the decline of Scythian power and the emergence of Sarmatian dominance. These developments reshaped political, economic, and cultural trajectories, paving the way for future interactions between nomadic tribes and sedentary communities, thus significantly influencing the region’s subsequent historical evolution.

East Europe (189–46 BCE): Consolidation of Sarmatian Power and Expansion of Hellenistic Influence

Political and Military Developments

Sarmatian Consolidation and Expansion

Between 189 and 46 BCE, the Sarmatians solidified their dominance over the Pontic–Caspian steppe, extending their influence westward toward central and eastern Europe. Their formidable cavalry units increasingly interacted with, and sometimes clashed with, emerging European tribes, such as the early Germanic groups and Celtic tribes.

Growth and Influence of the Bosporan Kingdom

The Bosporan Kingdom expanded significantly, incorporating territories previously held by smaller tribal states like Sindica. The kingdom served as a vital political and economic hub linking Greek city-states, local tribes, and powerful nomadic confederations such as the Sarmatians.

Economic and Technological Developments

Enhanced Eurasian Trade Networks

Sarmatian control of key trade routes facilitated thriving commerce linking Central Asia, Eastern Europe, and the Mediterranean. Commodities such as precious metals, furs, and horses moved extensively through these routes, significantly enriching Sarmatian and Bosporan elites.

Continued Military Innovations

The Sarmatians further refined cavalry warfare, particularly their heavily armored horsemen (cataphracts), influencing European and Central Asian military tactics. Technological improvements in metallurgy allowed for stronger armor and weaponry, which became increasingly common among Eurasian warriors.

Cultural and Artistic Developments

Flourishing Sarmatian Art

Sarmatian artistic traditions flourished, showcasing sophisticated metalwork, intricate jewelry, and richly decorated weaponry. The fusion of steppe and Mediterranean styles became more pronounced, particularly in regions near the Bosporan Kingdom.

Intensified Hellenistic Influence

The Hellenistic cultural presence grew markedly in regions adjacent to the Bosporan Kingdom and throughout Sindica. Greek cultural and artistic elements permeated local traditions, visible in burial practices, pottery, coinage, and urban architecture.

Settlement Patterns and Urban Development

Expansion and Urbanization of Settlements

Urban centers in the Bosporan Kingdom and surrounding territories expanded significantly, serving as administrative, trade, and cultural hubs. Cities such as Panticapaeum (modern Kerch) thrived, reflecting increased economic prosperity and political stability.

Rise of the Zarubintsy and Przeworsk Cultures

The Zarubintsy and Przeworsk cultures continued to expand, demonstrating more complex settlement patterns and fortified communities. These cultures displayed enhanced socio-economic organization and interactions with surrounding Sarmatian and Hellenistic influences.

Social and Religious Developments

Reinforcement of Elite Dominance

Sarmatian society remained distinctly hierarchical, dominated by elite warriors and chieftains whose status and wealth were increasingly visible through elaborate burial sites, ornate jewelry, and ceremonial weaponry.

Deepening Religious Syncretism

Religious practices continued to reflect syncretism, integrating Greek, Iranian, and local steppe traditions. Rituals and religious iconography became increasingly eclectic, incorporating diverse symbolism from these interacting cultural spheres.

Long-Term Consequences and Historical Significance

The era from 189 to 46 BCE represented the high point of Sarmatian political and cultural influence in East Europe, closely interwoven with intensified Hellenistic expansion from the Bosporan Kingdom. These interactions contributed to enduring cultural exchanges and laid the foundations for future developments in regional trade, military strategies, and socio-political structures.

The Greeks of the Tauric Chersonese and the Cimmerian Bosporus (Crimea and Straits of Kerch), prosperous from the fourth century BCE, have maintained a free constitution of the Greek type and fought for their continued independence against the Scythians of southern Russia, against the native Tauri of the southern Crimea, and against the kings of Bosporus in the west.

They traded with Athens and cities on the Pontic coast in the early period and with Delos, Rhodes, and Delphi in the Hellenistic Age.

Having turned to Pontus for protection against the Scythians, the region is subsequently incorporated into the Pontic Empire of Mithridates VI.

Viewing Mithridates as a deliverer from their Scythian enemies, they gladly surrender their independence in about 110 BCE in return for the protection given to them by his armies.

The Sarmatians, who had emerged in a region of the steppe to the east of the Don River and south of the Ural Mountains in Eastern Europe in the seventh century BCE, have for centuries lived in relatively peaceful coexistence with their Scythian neighbors to the west.

They spill over the Don in the third century BCE to attack the Scythians on the Pontic steppe to the north of the Black Sea: they are to dominate these territories over the next five centuries.

Like the Scythians, Sarmatians are of a Caucasoid appearance, and before the arrival of the Huns (fourth century CE) it is thought that few had Asiatic or Turco-Mongol features.

Sarmatian noblemen often reach one oint seven to one point eight meters (five-feet seven inches to five feet ten inches) as measured from skeletons, and they have sturdy bones, long hair, and beards.

The Sarmatians drive their Scythian kinsmen into the delta of the Danube and the Crimea peninsula in about the second century BCE, at which point the Tauri become subject-allies of the Scythian king Skilurus and vanish from history.

Skilurus controls the ancient trade emporium of Pontic Olbia, where he mints coins.

In order to gain advantage against Chersonesos, he allies himself with the Sarmatian tribe of Rhoxolani.

In response, Chersonesos forges an alliance with Mithridates VI of Pontus.

Skilurus dies during a war against Mithridates, a decisive conflict for supremacy in the Pontic steppe.

His son Palacus succeeds him.

Soon after his death, the Scythians are defeated by by Diophantus, general of Mithridates VI, in about 108 BCE).

Diophantus is active in Mithridates' campaigns in the Bosporan Kingdom and elsewhere around the Black Sea, although their chronology is disputed.

An inscription found during the excavations in Chersonesos glorifies Diophantus as "the first foreign invader to conquer the Scythians".

During his first Crimean expedition, he relieves the siege of Chersonesos by the Scythian king Palacus and subdues his allies, the Tauri.

He finishes this campaign at Scythian Neapolis.

During the second campaign, Diophantus checks another invasion of the Scythians, who had joined their forces with the Rhoxolanoi under Tasius.

At one point during these campaigns he establishes a stronghold at Eupatorium on the eastern shore of the Crimea.

Around 107 BCE, Mithridates dispatches Diophantes to Panticapaeum with the task of persuading the Bosporan king Paerisades V to cede his kingdom to Mithridates.

While he is in the city, the Scythians, led by a certain Saumacus, revolted and kill Paerisades, while Diophantes barely manages to escape to Chersonesos.

Back in Pontus, Diophantes rallies his forces and sails to Crimea with a large fleet.

The Scythian uprising is put down and the Bosporan kingdom is reduced to a dependency of Pontus.

Either Skilurus or his son and successor Palacus are buried in a mausoleum at Scythian Neapolis, used from about 100 BCE to about 100 CE.
