How the European Map Has Changed Over 2,400 Years
The history of Europe is breathtakingly complex. While there are rare exceptions like Andorra and Portugal, which have had remarkably static borders for hundreds of years, jurisdiction over portions of the continent’s landmass have changed hands innumerable times.
Today’s video comes to us from YouTube channel Cottereau, and it shows the evolution of European map borders starting from 400 BC. Empires rise and fall, invasions sweep across the continent, and modern countries slowly begin to take shape (with the added bonus of an extremely dramatic instrumental).
Below are nine highlights and catalysts that shifted the dividing lines of the European map:
146 BC – A Year of Conquest
146 BC was a year of conquest and expansion for the Roman Republic. The fall of Carthage left the Romans in control of territory in North Africa, and the ransack and destruction of the Greek city-state of Corinth also kickstarted an era of Roman influence in that region. These decisive victories paved the way for the Roman Empire’s eventual domination of the Mediterranean.
117 AD – Peak Roman Empire
The peak of the Roman Empire is one of the more dramatic moments shown on this animated European map. At its height, under Trajan, the Roman Empire was a colossal 1.7 million square miles (quite a feat in an era without motorized vehicles and modern communication tools). This enormous empire remained mostly intact until 395, when it was irreparably split into Eastern and Western regions.
370 AD – The Arrival of the Huns
Spurred on by severe drought conditions in Central Asia, the Huns reached Europe and found a Roman Empire weakened by currency debasement, economic instability, overspending, and increasing incursions from rivals along its borders.
The Huns waged their first attack on the Eastern Roman Empire in 395, but it was not until half a century later—under the leadership of Attila the Hun—that hordes pushed deeper into Europe, sacking and razing cities along the way. The Romans would later get their revenge when they attacked the quarreling Goths and Huns, bouncing the latter out of Central Europe.
1241 – The Mongol Invasion of Europe
In the mid-13th century, the “Golden Horde” led by grandsons of Genghis Khan, roared into Russia and Eastern Europe sacking cities along the way. Facing invasion from formidable Mongol forces, central European princes temporarily placed their regional conflicts aside to defend their territory. Though the Mongols were slowly pushed eastward, they loomed large on the fringes of Europe until almost the 16th century.
1362 – Lithuania
Today, Lithuania is one of Europe’s smallest countries, but at its peak in the middle ages, it was one of the largest states on the continent. A pivotal moment for Lithuania came after a decisive win at the Battle of Blue Waters. This victory stifled the expansion of the Golden Horde, and brought present-day Ukraine into its sphere of influence.
1648 – Kleinstaaterei
The end of the Holy Roman Empire highlights the extreme territorial fragmentation in Germany and neighboring regions, in an era referred to as Kleinstaaterei.
Even as coherent nation states formed around it, the Holy Roman Empire and its remnants wouldn’t coalesce until Germany rose from the wreckage of the Franco-Prussian War in 1871. Unification helped position Germany as a major power, and by 1900 the country had the largest economy in Europe.
1919 – The Ottoman Empire
The Ottoman Empire—a fixture in Eastern Europe for hundreds of years—was in its waning years by the beginning of the 20th century. The empire had ceded territory in two costly wars with Italy and Balkan states, and by the time the dust cleared on WWI, the borders of the newly minted nation of Turkey began at the furthest edge of continental Europe.
1942 – Expanding and Contracting Germany
At the furthest extent of Axis territory in World War II, Germany and Italy controlled a vast portion of continental Europe. The map below shows occupied land and areas of influence at the height of Germany’s territorial expansion.
After the war, Germany again became fragmented into occupation zones—this time, overseen by the United States, France, Great Britain, and the Soviet Union. Germany would not be made whole again until 1990, when a weakening Soviet Union loosened its grip on East Germany.
1991 – Soviet Dissolution
In the decades following WWII, the political boundaries of the European map remained relatively stable—that is, until the dissolution of the Soviet Union in 1991. Almost overnight, the country’s entire western border splintered into independent nations. When the dust settled, there were 15 breakaway republics, six of which were in Europe.

Visualizing Population Density Patterns in Six Countries
These maps show the population density of several countries, using 3D spikes to denote where more people live.
As of 2022, Earth has 8 billion humans. By 2050, the population is projected to grow to 10 billion.
In the last 50 years, the global population more than quadrupled. But none of this growth has been evenly spread out, including within countries.
This series of 3D maps from Terence Teo, an associate professor at Seton Hall University, renders the population density of six countries using open-source data from Kontur Population. He used popular programming language R and a path-tracing package, Rayshader, to create the maps.
France and Germany: Population Density Spikes and Troughs
Let’s take a look at how the population spreads out in different countries around the world. Click the images to explore higher-resolution versions.
France is the world’s 7th largest economy and second-most-populous country in the EU with 65 million people. But a staggering one-fifth of the French population lives in Paris and its surrounding metro—the most populous urban area in Europe.
Many residents in the Paris metropolitan area are employed in the service sector, which makes up one-third of France’s $2.78 trillion gross domestic product.
Unlike France, Germany has many dense cities and regions, with Berlin, Munich, Stuttgart, and Cologne all having over a million residents. Berlin is the most populated at 3.5 million residents in the city proper, and 6 million in the wider urban area.
That said, the relatively recent reunification of West and East Germany in 1991 meant that post-WWII growth was mostly concentrated in West Germany (and West Berlin).
Italy and Chile: Coast to Coast
In Italy, another phenomenon affects population density and urban development—a sprawling coastline.
Despite having a large population of 59 million and large metropolitan areas throughout, Italy’s population spikes are closer to the water.
The port cities of Genoa, Napoli, and Palermo all have large spikes relative to the rest of the country, as does the capital, Rome. Despite its city center located 15 miles inland from the sea, it extends to the shore through the district of Ostia, where the ancient port of Rome existed.
Meanwhile in Chile, stuck between the Andes to the east and the Pacific Ocean to the west, population spikes corroborate with its many port towns and cities.
However, the country is more concentrated than Italy, with 40% of its residents congregating around the capital of Santiago.
Turkey and Canada: Marred by Mountains and Climes
Though Chile has difficulties with terrain, it is relatively consistent. Other countries have to attempt to settle many different climes—regions defined by their climates.
Mountains to the south and east, a large, semi-arid plateau, and even a small desert leave few centers of urban growth in Türkiye.
Predictably, further west, as the elevation comes down to the Aegean and Mediterranean Seas, population spikes begin to heighten. The largest of course is the economic and cultural hub of Istanbul, though the capital Ankara is also prominent with more than 5 million residents.
In Canada, the Rocky Mountains to the west and freezing cold temperatures in the center and north account for the large country’s relative emptiness.
Though population spikes in Western Canada are growing rapidly, highly populous urban centers are noticeably concentrated along the St. Lawrence River, with the Greater Toronto Area accounting for more than one-sixth of the country’s 39 million people.
According to the World Bank, more than half of the world’s population currently lives in cities, and that trend is only growing.
By 2050, 7 out of 10 people are projected to live in cities. This congregation makes cities a beehive of productivity and innovation—with more than 80% of the world’s GDP being generated at these population centers.
It’s in this context that mapping and studying urban development becomes all the more important, particularly as policymakers try their hand at sustainable urban planning.
As Teo puts it:
“By showing where people are (and are not), they show us where political and economic power is concentrated, and perhaps where and who our governments represent.”
