Eastern Europe
Modern-day Countries in this region
Bronze Age
Eastern Europe during the Bronze Age saw the rise of early societies tied to the Pontic-Caspian Steppe, a region often credited as the homeland of Indo-European peoples. Cultures such as the Yamna (or Pit Grave) culture flourished, characterized by their use of kurgans (burial mounds), domesticated horses, and early wheeled vehicles.
To the west of the steppes, the Trzciniec culture and the Srubnaya culture emerged, showcasing advanced metallurgy and the construction of fortified settlements. These societies began using bronze tools and weapons, leading to increased agricultural productivity and more structured social hierarchies. In present-day Ukraine, the Catacomb culture developed burial practices involving underground chambers, reflecting growing complexity in religious and societal norms.
Bronze Age
Iron Age
The Cimmerians, a nomadic people from the Pontic Steppe, dominated much of the region during this period, eventually giving way to the Scythians around the 8th century BCE.
The Scythians, skilled horsemen and warriors, controlled vast territories stretching from the Black Sea to the Ural Mountains. Their sophisticated art, known as Scythian animal style, reflected their nomadic lifestyle and reverence for nature. They interacted with Greek colonies along the northern Black Sea coast, such as Olbia and Chersonesus, establishing early trade connections between the steppe and the Mediterranean world.
In the forested regions of modern Belarus and Russia, the Dnieper-Dvina culture thrived, developing early ironworking and interacting with neighboring tribes. These groups laid the foundation for later Slavic cultures.

Greek Poleis
Independent Greek poleis in the Mediterranean Basin between the 8th and 4th century BC.
Antiquity
The late Iron Age and early Antiquity saw the continuation of Scythian dominance, which was later challenged by the Sarmatians, another steppe people who migrated into the region. The northern Black Sea coast flourished as a cultural and economic hub due to the influence of Greek city-states, such as Odessos (modern Odessa) and Panticapaeum.
In the 4th century BCE, the Kingdom of Bosporus arose as a Greco-Scythian polity, blending steppe traditions with Hellenistic culture. This kingdom became an essential link in the trade of grain, fish, and slaves between the steppes and the Mediterranean.
By the late Antiquity period, the arrival of the Goths, followed by the Huns, disrupted the region's stability. The Gothic kingdoms, particularly those of the Tervings and Greuthungs, played a central role in the weakening of the Roman Empire. The Hun invasion under Attila devastated large parts of Eastern Europe, driving many tribes into Roman territories.
Slavic tribes began to emerge during this time, particularly in modern-day Belarus, Ukraine, and western Russia. These groups were the ancestors of the East Slavs and formed the cultural core of the region in subsequent centuries.

Early Middle Ages
The collapse of Roman influence and the decline of steppe empires allowed for the rise of the Slavic peoples as the dominant group in Eastern Europe. The East Slavs began to consolidate into tribal unions such as the Polyani, Drevlyani, and Krivichi, which would later form the foundations of Russian, Ukrainian, and Belarusian identities.
In the 9th century, the region witnessed the rise of Kievan Rus’, a federation of East Slavic tribes led by the Varangians (Norsemen). Founded by Rurik in Novgorod, the Rus’ expanded southward under his successors, eventually establishing Kiev as their capital.

In the 13th century, the Mongol invasion led by Batu Khan devastated Kievan Rus’. Many cities, including Kiev, were sacked, and the region came under the control of the Golden Horde, a Mongol khanate. This marked a turning point as power shifted northward to regions like Vladimir and Novgorod.

Under rulers such as Ivan I Kalita, Moscow expanded its influence, eventually becoming the center of resistance against the Mongols. The Battle of Kulikovo in 1380 symbolized the weakening of Mongol control.

In present-day Belarus and Ukraine, the Polish-Lithuanian Commonwealth dominated much of the territory. The Union of Brest (1596) sought to unify Orthodox Christians with the Catholic Church, creating the Uniate (Greek Catholic) Church, but it caused deep divisions in the region. Ukrainian Cossacks, semi-autonomous warrior communities, emerged as defenders of Orthodox Christianity and local autonomy. Their Khmelnytsky Uprising (1648) against Polish rule led to the creation of the Cossack Hetmanate, which later aligned with the Russian Tsardom under the Treaty of Pereyaslav (1654).
By the late 17th century, Russia began asserting dominance in Eastern Europe. Under Peter the Great, Russia became a major European power. Peter’s reforms modernized the military, established Saint Petersburg, and secured access to the Baltic Sea through victory in the Great Northern War (1700-1721).

The 19th century was a period of rapid change in Eastern Europe, dominated by the Russian Empire. Alexander I and his successors faced increasing pressure from nationalist movements and revolutionary ideals spreading across Europe.
In Ukraine and Belarus, Russification policies sought to suppress local languages and cultures, promoting Russian identity. The Uniate Church was outlawed in Belarus (1839) and much of Ukraine. However, national consciousness began to rise among Ukrainians and Belarusians, particularly in rural areas, where language and folk traditions persisted.
The Crimean War (1853-1856) exposed the weaknesses of the Russian Empire, leading to significant reforms under Alexander II, including the abolition of serfdom (1861). These reforms, however, failed to alleviate widespread poverty and social inequality, leading to unrest.
Industrialization began to transform parts of Ukraine, particularly in the Donbas region, where coal and steel industries emerged. This development laid the groundwork for future conflicts over the region’s resources.

In the aftermath, Ukraine declared independence in 1918 as the Ukrainian People’s Republic, while Belarus briefly proclaimed independence as the Belarusian Democratic Republic. Both states were short-lived, as the Red Army regained control and incorporated the territories into the USSR.
During the interwar period, western Ukraine and Belarus were annexed by Poland, while the rest became Soviet republics. The Holodomor (1932-1933), a man-made famine in Soviet Ukraine, caused millions of deaths and is widely regarded as an act of genocide. Collectivization and Stalinist purges devastated rural populations in both Ukraine and Belarus.
World War II was catastrophic for the region. The Nazi invasion of the USSR (Operation Barbarossa, 1941) led to the occupation of Ukraine and Belarus. Both regions suffered immense destruction, with entire cities razed and millions of civilians killed. Partisan resistance movements were active in Belarus, playing a critical role in harassing Nazi forces.
By the war’s end, Eastern Europe lay in ruins. Ukraine and Belarus, now Soviet Socialist Republics, faced the immense task of rebuilding under Stalin’s authoritarian rule.

By the late 1980s, the policies of Glasnost and Perestroika under Mikhail Gorbachev led to greater openness and demands for independence. National movements in Ukraine and Belarus gained momentum, culminating in the collapse of the Soviet Union in 1991.
